+LoRa concentrator HAL user manual
+============================
+
+1. Introduction
+---------------
+
+The LoRa concentrator Hardware Abstraction Layer is a C library that allow you
+to use a Semtech concentrator chip through a reduced number of high level C
+functions to configure the hardware, send and receive packets.
+
+The Semtech LoRa concentrator is a digital multi-channel multi-standard packet
+radio used to send and receive packets wirelessly using LoRa or FSK modulations.
+
+2. Components of the library
+----------------------------
+
+The library is composed of 6 modules:
+
+* loragw_hal
+* loragw_reg
+* loragw_mcu
+* loragw_com
+* loragw_aux
+* loragw_radio
+
+The library also contains basic test programs to demonstrate code use and check
+functionality.

+This is the main module and contains the high level functions to configure and
+use the LoRa concentrator:
+
+* lgw_board_setconf, to set the configuration of the concentrator
+* lgw_rxrf_setconf, to set the configuration of the radio channels
+* lgw_rxif_setconf, to set the configuration of the IF+modem channels
+* lgw_txgain_setconf, to set the configuration of the concentrator gain table
+* lgw_start, to apply the set configuration to the hardware and start it
+* lgw_stop, to stop the hardware
+* lgw_receive, to fetch packets if any was received
+* lgw_send, to send a single packet (non-blocking, see warning in usage section)
+* lgw_status, to check when a packet has effectively been sent
+
+For an standard application, include only this module.
+The use of this module is detailed on the usage section.
+
+/!\ When sending a packet, there is a 1.5 ms delay for the analog circuitry to
+start and be stable (TX_START_DELAY).
+
+In 'timestamp' mode, this is transparent: the modem is started 1.5ms before the
+user-set timestamp value is reached, the preamble of the packet start right when
+the internal timestamp counter reach target value.
+
+In 'immediate' mode, the packet is emitted as soon as possible: transferring the
+packet (and its parameters) from the host to the concentrator takes some time,
+then there is the TX_START_DELAY, then the packet is emitted.
+
+In 'triggered' mode (aka PPS/GPS mode), the packet, typically a beacon, is
+emitted 1.5ms after a rising edge of the trigger signal. Because there is no
+way to anticipate the triggering event and start the analog circuitry
+beforehand, that delay must be taken into account in the protocol.
+
+### 2.2. loragw_mcu ###
+
+This module wraps the HAL functions into commands to be sent to the concentrator
+MCU.
+
+The HAL structures are serialized in a byte array and sent over the COM/USB
+interface.
+
+* board configuration
+* send/receive packets
+* ...
+
+### 2.3. loragw_reg ###
+
+This module is used to access to the LoRa concentrator registers by name instead
+of by address:
+
+* lgw_connect, to initialise and check the connection with the hardware
+* lgw_disconnect, to disconnect the hardware
+* lgw_soft_reset, to reset the whole hardware by resetting the register array
+* lgw_reg_check, to check all registers vs. their default value and output the
+result to a file
+* lgw_reg_r, read a named register
+* lgw_reg_w, write a named register
+* lgw_reg_rb, read a name register in burst
+* lgw_reg_wb, write a named register in burst
+
+This module handles pagination, read-only registers protection, multi-byte
+registers management, signed registers management, read-modify-write routines
+for sub-byte registers and read/write burst fragmentation to respect SPI
+maximum burst length constraints.
+
+It make the code much easier to read and to debug.
+Moreover, if registers are relocated between different hardware revisions but
+keep the same function, the code written using register names can be reused "as
+is".
+
+If you need access to all the registers, include this module in your
+application.
+
+**/!\ Warning** please be sure to have a good understanding of the LoRa
+concentrator inner working before accessing the internal registers directly.
+
+### 2.4. loragw_com ###
+
+This module contains the functions to access the LoRa concentrator register
+array through the USB/UART interface:
+
+* lgw_com_r to read one byte
+* lgw_com_w to write one byte
+* lgw_com_rb to read two bytes or more
+* lgw_com_wb to write two bytes or more
+
+Please *do not* include that module directly into your application.
+
+**/!\ Warning** Accessing the LoRa concentrator register array without the
+checks and safety provided by the functions in loragw_reg is not recommended.
+
+### 2.5. loragw_aux ###
+
+This module contains a single host-dependant function wait_ms to pause for a
+defined amount of milliseconds.
+
+The procedure to start and configure the LoRa concentrator hardware contained in
+the loragw_hal module requires to wait for several milliseconds at certain
+steps, typically to allow for supply voltages or clocks to stabilize after been
+switched on.
+
+An accuracy of 1 ms or less is ideal.
+If your system does not allow that level of accuracy, make sure that the actual
+delay is *longer* that the time specified when the function is called (ie.
+wait_ms(X) **MUST NOT** before X milliseconds under any circumstance).
+
+If the minimum delays are not guaranteed during the configuration and start
+procedure, the hardware might not work at nominal performance.
+Most likely, it will not work at all.
+
+### 2.6. loragw_radio ###
+
+This module contains functions to handle the configuration of SX125x radios.
+
+
+3. Software build process
+--------------------------
+
+### 3.1. Details of the software ###
+
+The library is written following ANSI C conventions but using C99 explicit
+length data type for all data exchanges with hardware and for parameters.
+
+The loragw_aux module contains POSIX dependant functions for millisecond
+accuracy pause.
+For embedded platforms, the function could be rewritten using hardware timers.
+
+### 3.2. Building options ###
+
+All modules use a fprintf(stderr,...) function to display debug diagnostic
+messages if the DEBUG_xxx is set to 1 in library.cfg
+
+### 3.3. Building procedures ###
+
+For cross-compilation set the ARCH and CROSS_COMPILE variables in the Makefile,
+or in your shell environment, with the correct toolchain name and path.
+ex:
+export PATH=/home/foo/rpi-toolchain/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin:$PATH
+export ARCH=arm
+export CROSS_COMPILE=arm-linux-gnueabihf-
+
+The Makefile in the libloragw directory will parse the library.cfg file and
+generate a config.h C header file containing #define options.
+Those options enables and disables sections of code in the loragw_xxx.h files
+and the *.c source files.
+
+The library.cfg is also used directly to select the proper set of dynamic
+libraries to be linked with.
+
+### 3.4. Export ###
+
+Once build, to use that library on another system, you need to export the
+following files :
+
+* libloragw/library.cfg -> root configuration file
+* libloragw/libloragw.a -> static library, to be linked with a program
+* libloragw/readme.md -> required for license compliance
+* libloragw/inc/config.h -> C configuration flags, derived from library.cfg
+* libloragw/inc/loragw_*.h -> take only the ones you need (eg. _hal and _gps)
+
+After statically linking the library to your application, only the license
+is required to be kept or copied inside your program documentation.
+
+4. Hardware dependencies
+------------------------
+
+### 4.1. Hardware revision ###
+
+The loragw_reg and loragw_hal are written for a specific version on the Semtech
+hardware (IP and/or silicon revision).
+
+This code has been written for:
+
+* Semtech SX1301 chip
+* Semtech SX1257 or SX1255 I/Q transceivers
+
+The library will not work if there is a mismatch between the hardware version
+and the library version. You can use the test program test_loragw_reg to check
+if the hardware registers match their software declaration.
+
+### 4.2. USB/UART communication ###
+
+loragw_com contains 4 functions (read, write, burst read, burst write) that are
+platform-dependant.
+The functions must be rewritten depending on the communication bridge you use:
+
+* USB/UART over linux tty port (provided)
+
+You can use the test program test_loragw_com to check that the USB communication
+is working.
+
+
+5. Usage
+--------
+
+### 5.1. Setting the software environment ###
+
+For a typical application you need to:
+
+* include loragw_hal.h in your program source
+* link to the libloragw.a static library during compilation
+* link to the librt library due to loragw_aux dependencies (timing functions)
+
+For an application that will also access the concentrator configuration
+registers directly (eg. for advanced configuration) you also need to:
+
+* include loragw_reg.h in your program source
+
+### 5.2. Using the software API ###
+
+To use the HAL in your application, you must follow some basic rules:
+
+* configure the radios path and IF+modem path before starting the radio
+* the configuration is only transferred to hardware when you call the *start*
+ function
+* you cannot receive packets until one (or +) radio is enabled AND one (or +)
+ IF+modem part is enabled AND the concentrator is started
+* you cannot send packets until one (or +) radio is enabled AND the concentrator
+ is started
+* you must stop the concentrator before changing the configuration
+
+A typical application flow for using the HAL is the following:
+
+ <configure the radios and IF+modems>
+ <start the LoRa concentrator>
+ loop {
+ <fetch packets that were received by the concentrator>
+ <process, store and/or forward received packets>
+ <send packets through the concentrator>
+ }
+ <stop the concentrator>
+
+**/!\ Warning** The lgw_send function is non-blocking and returns while the
+LoRa concentrator is still sending the packet, or even before the packet has
+started to be transmitted if the packet is triggered on a future event.
+While a packet is emitted, no packet can be received (limitation intrinsic to
+most radio frequency systems).
+
+Your application *must* take into account the time it takes to send a packet or
+check the status (using lgw_status) before attempting to send another packet.
+
+Trying to send a packet while the previous packet has not finished being send
+will result in the previous packet not being sent or being sent only partially
+(resulting in a CRC error in the receiver).
+
+### 5.3. Debugging mode ###
+
+To debug your application, it might help to compile the loragw_hal function
+with the debug messages activated (set DEBUG_HAL=1 in library.cfg).
+It then send a lot of details, including detailed error messages to *stderr*.

Core library: libloragw +----------------------------- + +This directory contains the sources of the library to build a LoRa Picocell +Gateway based on a Semtech LoRa multi-channel RF receiver (a.k.a. concentrator). +Once compiled all the code is contained in the libloragw.a file that will be +statically linked (ie. integrated in the final executable). +The library implements the communication with the concentrator embedded MCU +through a serial port. + +The library also comes with a bunch of basic tests programs that are used to +test the different sub-modules of the library. + +## 2. Helper programs +--------------------- + +Those programs are included in the project to provide examples on how to use +the HAL library, and to help the system builder test different parts of it. + +### 2.1. util_pkt_logger ### + +This software is used to set up a LoRa concentrator using a JSON configuration +file and then record all the packets received in a log file, indefinitely, until +the user stops the application. + +### 2.2. util_com_stress ### + +This software is used to check the reliability of the link between the host +platform (on which the program is run) and the LoRa concentrator register file +that is the interface through which all interaction with the LoRa concentrator +happens. + +### 2.3. util_tx_test ### + +This software is used to send test packets with a LoRa concentrator. The packets +contain little information, on no protocol (ie. MAC address) information but +can be used to assess the functionality of a gateway downlink using other +gateways as receivers. + +### 2.4. util_tx_continuous ### + +This software is used to set LoRa concentrator in Tx continuous mode, +for spectral measurement. + +### 2.5. util_boot ### + +This software is used to jump to the PicoCell Gateway bootloader for programming +the MCU with a new firmware. +Please refer to the readme of picoGW_mcu repository for more information about +MCU flash programming. + +### 2.6. util_chip_id ### + +This software is used to obtain the unique id of the PicoCell gateway (the +64 bits unique id extracted from the STM32 unique id registers). + +## 4. User Guide +---------------- + +[A detailed PicoCell GW user guide is available here](http://www.semtech.com/images/datasheet/picocell_gateway_user_guide.pdf) + +## 5. Changelog +--------------- + +### v0.2.2 ### + +* HAL: updated MCU firmware version to match with picoGW_mcu V0.2.1 release. + +### v0.2.1 ### + +* HAL: Fixed bug in lgw_mcu_receive() which was preventing from fetching more +than 2 packets simultaneously. + +### v0.2.0 ### + +* HAL: reverted AGC FW to version 4, as v5 was necessary to fix a HW bug which +has been fixed since rev V02A of the picoCell reference design. +* HAL: fixed a bug lgw_com_send_command() function to prevent from hanging when +writing on the COM link was not possible. +* HAL: fixed memory alignment on FSK syncword configuration. + +### v0.1.2 ### + +* HAL: fixed a wrong copy size and position of MCU unique ID in lgw_mcu_get_unique_id(). +* HAL: disabled some logs. + +### v0.1.1 ### + +* HAL: fixed MCU command wrong size in lgw_mcu_commit_radio_calibration(). +* HAL: fixed MCU reset sequence to wait for MCU to complete reset and reinit +the communication bridge before exiting. This is to avoid issues when restarting +the concentrator after exit. + +### v0.1.0 ### + +* HAL: code clean-up/refactoring +* HAL: serial port configuration to handle both USB or UART communication with +mcu. +* util_boot: only used to jump to the MCU bootloader. +* util_chip_id: no more command line parameter, just print the PicoCell GW +unique ID on the console. +* HAL/util_*: added a parameter to lgw_connect() function to specify the COM +device path to be used to communicate with the concentrator board (tty...). + +### v0.0.1 ### + +* Initial release + + +## 6.

Introduction +---------------- + +This software is used to set up a LoRa concentrator using a JSON configuration +file and then record all the packets received in a log file, indefinitely, until +the user stops the application. +No filtering is done and all packets that are LoRa packets with the correct RF +parameters (frequency, datarate, bandwidth) should appear in the log. + +2. Dependencies +---------------- + +This program uses the Parson library (http://kgabis.github.com/parson/) by +Krzysztof Gabis for JSON parsing. +Many thanks to him for that very practical and well written library. + +This program is a typical example of LoRa concentrator HAL usage for receiving +packets. + +Only high-level functions are used (the ones contained in loragw_hal) so there +is no hardware dependencies assuming the HAL is matched with the proper version +of the hardware. +Data structures of the received packets are accessed by name (ie. not at a +binary level) so new functionalities can be added to the API without affecting +that program at all. + +It was tested with v1.3.0 of the libloragw library, and should be compatible +with any later version of the library assuming the API is downward-compatible. + +3. Usage +--------- + +To stop the application, press Ctrl+C. + +The only optional parameter when launching the application is the log rotation +time (in seconds). + +The way the program takes configuration files into account is the following: + * if there is a debug_conf.json parse it, others are ignored + * if there is a global_conf.json parse it and look for the next file + * if there is a local_conf.json parse it +If some parameters are defined in both global and local configuration files, the +local definition overwrites the global definition. + +The global configuration file should be exactly the same throughout your +network, contain all global parameters (parameters for "sensor" radio channels) +and preferably default "safe" values for parameters that are specific for each +gateway (eg. specify a default MAC address). + +If you have build the libloragw library for a specific radio band (eg. ETSI +868 MHz band) a ready-to-use global_conf.json file is generated by the Makefile +with a set of channels typical for a 'LoRa MAC' network application. +If you don't specify a radio band, an empty global_conf.json is generated and +must be filled with the settings you need. + +The local configuration file should contain parameters that are specific to each +gateway (eg. MAC address, frequency for backhaul radio channels). + +In each configuration file, the program looks for a JSON object named +"SX1301_conf" that should contain the parameters for the LoRa concentrator board +(RF channels definition, modem parameters, etc) and another JSON object called +"gateway_conf" that should contain the gateway parameters (gateway MAC address, +IP address of the LoRa MAC controller, network authentication parameters, etc). + +To learn more about the JSON configuration format, read the provided JSON files +and the API documentation. A dedicated document will be available later on. + +The received packets are put in a CSV file whose name include the MAC address of +the gateway in hexadecimal format and a UTC timestamp of log starting time in +ISO 8601 recommended compact format: +yyyymmddThhmmssZ (eg. 20131009T172345Z for October 9th, 2013 at 5:23:45PM UTC) + +To able continuous monitoring, the current log file is closed is closed and a +new one is opened every hour (by default, rotation interval is settable by the +user using -r command line option). +No packet is lost during that rotation of log file. +Every log file but the current one can then be modified, uploaded and/or deleted +without any consequence for the program execution. + +4.

Introduction +---------------- + +This software is used to send test packets with a LoRa concentrator. The packets +contain little information, on no protocol (ie. MAC address) information but +can be used to assess the functionality of a gateway downlink using other +gateways as receivers. + +2. Dependencies +---------------- + +This program is a typical example of LoRa concentrator HAL usage for sending +packets. + +Only high-level functions are used (the ones contained in loragw_hal) so there +is no hardware dependencies assuming the HAL is matched with the proper version +of the hardware. +Data structures of the sent packets are accessed by name (ie. not at a +binary level) so new functionalities can be added to the API without affecting +that program at all. + +3. Usage +--------- + +The application runs until the specified number of packets have been sent. +Press Ctrl+C to stop the application before that. + +Use the -h to get help and details about available options. + +The payload content is: +[T][E][S][T][packet counter MSB][packet counter LSB] followed by ASCII padding. + +All LoRa data is scrambled and whitened, so the padding has no influence +whatsoever on the packet error rate. + +4.
