wayne roberts / Mbed OS lora-file-transfer-example

transfer files from mbed-os block device (i.e. SD card) over LoRa radio.

Dependencies:   sx12xx_hal

radio chip selection

Radio chip driver is not included, allowing choice of radio device.
If you're using SX1272 or SX1276, then import sx127x driver into your program.
if you're using SX1261 or SX1262, then import sx126x driver into your program.
if you're using SX1280, then import sx1280 driver into your program.
If you're using NAmote72 or Murata discovery, then you must import only sx127x driver.

This program uses mbed serial terminal at 115200 8N1.
Files (on SD Card) are transferred between two LoRa devices.
Use ? question mark to see available commands on serial terminal.
Send file to other side using send /fs/somefile, then use cmp /fs/somefile to compare the file on the other side of radio link with local file with same name.
Use cmp to test radio link.

rm command to delete files must not include /fs/ directory prefix, filename only.
send and cmp require /fs/ directory.

SD Card

SD card driver must be enabled in mbed_app.json with the line "target.components_add": ["SD"]
Pins for SD card connection can be overridden as shown in mbed_app.json.
The default pin configuration for SD card is found in mbed_lib.json in mbed-os/components/storage/blockdevice/COMPONENT_SD/.
If no pin configuration exists in this mbed_lib.json, or needs to be changed, the included mbed_app.json is example pin declaration for SD card.

FAT filesystem is only used in this project for demonstration purpose; for easily copying files to SD card.
However, for production projects, LittleFileSystem needs to be used instead for reliability and wear leveling.

Platforms such as K64F have SD card slot already.
See all boards with arduino shield connector and SD card here. (arduino connector needed for LoRa radio board)
