Integrate easy-connect, fix serial, fix warning (#176)
Integrate easy-connect
- we can remove all the external RF-drivers from main folder
- get easy-connect into use
- remove all the complicated network stuff
Fix serial - we don't need raw serial and we don't need to initialize it
if we set the right stuff to mbed_app.json (added). Plain printf() works
and it even does type checking now. (Points to Kevin Bracey on this).
Start the thread in a non-deprecated way using callback to remove one compiler
warning (again, points to Kevin Bracey).
Easy-connect ESP8266 TX/RX pins in different defines.
mbed-os-example-client has NEVER used 2 sets of WiFi pins, so need
to add a define to hack them into one set - otherwise it will not compile.
The cp command would not have worked if one would have changed
the compiler. Add UBLOX ODIN ETH config to be built as well,
now that we have figured out how to make the the ethernet work
on it.
Change also the WIFI to work with easy-connect. Easy-connect has 2 separate WIFIs,
so you have to choose between ESP8266 vs. ODIN. Thus, 2 config files are also needed,
one for ESP8266 and one for ODIN.

Yogesh Pande |
0:7d5ec759888b | 2 | |
Yogesh Pande |
0:7d5ec759888b | 3 | This is the mbed Client example for mbed OS (we also have one for [Linux](https://github.com/ARMmbed/mbed-client-linux-example)). It demonstrates how to register a device with mbed Device Connector, how to read and write values, and how to deregister. If you are unfamiliar with mbed Device Connector, we recommend that you read [the introduction to the data model](https://docs.mbed.com/docs/mbed-device-connector-web-interfaces/en/latest/#the-mbed-device-connector-data-model) first. |

mbed_official | 22:e39e09d79a63 | 21 | ## Supported Target hardware configurations |
mbed_official | 22:e39e09d79a63 | 22 | |
mbed_official | 22:e39e09d79a63 | 23 | This example has been tested in following configuration |
mbed_official | 22:e39e09d79a63 | 24 | * K64F + NXP MCR20 15.4 shield (mesh `NANOSTACK_FULL` mode) |
mbed_official | 22:e39e09d79a63 | 25 | * NUCLEO_F429ZI + ATMEL AT233 15.4 shield (mesh `LOWPAN_ROUTER` mode) |
mbed_official | 22:e39e09d79a63 | 26 | * K64F (Ethernet) |
mbed_official | 22:e39e09d79a63 | 27 | * NUCLEO_F429ZI (Ethernet) |
mbed_official | 62:077cbce2bd10 | 28 | * UBLOX_EVK_ODIN_W2 (WiFi & Ethernet - use the supplied `configs/eth_v4.json` for Ethernet) |
mbed_official | 22:e39e09d79a63 | 29 | * K64F + GROVE SEEED shield (Wifi) |
mbed_official | 22:e39e09d79a63 | 30 | * NUCLEO_F429ZI + GROVE SEEED shield (Wifi) |
mbed_official | 22:e39e09d79a63 | 31 | |
mbed_official | 22:e39e09d79a63 | 32 | Apart from this, this example can work on other mbed OS supported hardware boards which support any of the given network interface including Ethernet, WiFi, Mesh (6LoWPAN) or Thread, provided the configuration fulfills condition that the target hardware has TLS entropy implemented for it and the complete example configuration of mbed Client, selected network interface and mbed OS components fits into hardware's given memory size (Flash size and RAM size). |
mbed_official | 22:e39e09d79a63 | 33 | |
mbed_official | 62:077cbce2bd10 | 34 | To see how different targets are built please see the supplied `build_all.sh script`. |
mbed_official | 62:077cbce2bd10 | 35 | |
mbed_official | 21:b88cdeb5b302 | 36 | ## Requirements for non-K64F boards |
mbed_official | 21:b88cdeb5b302 | 37 | |
mbed_official | 21:b88cdeb5b302 | 38 | * This example requires TLS functionality to be enabled on mbed TLS. |
mbed_official | 21:b88cdeb5b302 | 39 | On devices where hardware entropy is not present, TLS is disabled by default. |
mbed_official | 21:b88cdeb5b302 | 40 | This would result in compile time failures or linking failures. |
mbed_official | 7:9a1ee269650b | 41 | |
mbed_official | 21:b88cdeb5b302 | 42 | To learn why entropy is required, read the |
mbed_official | 21:b88cdeb5b302 | 43 | [TLS Porting guide](https://docs.mbed.com/docs/mbed-os-handbook/en/5.2/advanced/tls_porting/). |
mbed_official | 21:b88cdeb5b302 | 44 | |
mbed_official | 21:b88cdeb5b302 | 45 | * On non-K64F boards, there is no unregistration functionality and |
mbed_official | 21:b88cdeb5b302 | 46 | button presses are simulated through timer ticks incrementing every 15 seconds. |
mbed_official | 7:9a1ee269650b | 47 | |

0:7d5ec759888b | 54 | ## Application setup |
Yogesh Pande |
0:7d5ec759888b | 55 | |
mbed_official | 21:b88cdeb5b302 | 56 | To configure the example application: |
Yogesh Pande |
0:7d5ec759888b | 57 | |
Yogesh Pande |
0:7d5ec759888b | 58 | 1. [Select the connection type](#connection-type). |
Yogesh Pande |

Yogesh Pande |
0:7d5ec759888b | 65 | |
Yogesh Pande |
0:7d5ec759888b | 66 | ### Connection type |
Yogesh Pande |
0:7d5ec759888b | 67 | |
Yogesh Pande |
0:7d5ec759888b | 68 | The application uses Ethernet as the default connection type. To change the connection type, set one of them in `mbed_app.json`. For example, to enable 6LoWPAN ND mode: |
Yogesh Pande |
0:7d5ec759888b | 69 | |
Yogesh Pande |
0:7d5ec759888b | 70 | ```json |
Yogesh Pande |
0:7d5ec759888b | 71 | "network-interface": { |
Yogesh Pande |
0:7d5ec759888b | 72 | "help": "options are ETHERNET,WIFI,MESH_LOWPAN_ND,MESH_THREAD.", |
Yogesh Pande |
0:7d5ec759888b | 73 | "value": "MESH_LOWPAN_ND" |
Yogesh Pande |
0:7d5ec759888b | 74 | } |
Yogesh Pande |
0:7d5ec759888b | 75 | ``` |
Yogesh Pande |
0:7d5ec759888b | 76 | |
Yogesh Pande |
0:7d5ec759888b | 77 | ### Client credentials |
Yogesh Pande |
0:7d5ec759888b | 78 | |
mbed_official | 21:b88cdeb5b302 | 79 | To register the application with the Connector service, you need to create and set the client side certificate. |
Yogesh Pande |
0:7d5ec759888b | 80 | |
Yogesh Pande |
0:7d5ec759888b | 81 | 1. Go to [mbed Device Connector](https://connector.mbed.com) and log in with your mbed account. |
mbed_official | 21:b88cdeb5b302 | 82 | 1. On mbed Device Connector, go to [My Devices > Security credentials](https://connector.mbed.com/#credentials) and click the **Get my device security credentials** to get new credentials for your device. |
mbed_official | 21:b88cdeb5b302 | 83 | 1. Replace the contents in the `security.h` file of this project's directory with the content copied above. |
Yogesh Pande |
0:7d5ec759888b | 84 | |
Yogesh Pande |
0:7d5ec759888b | 85 | ### 6LoWPAN ND and Thread settings |
Yogesh Pande |
0:7d5ec759888b | 86 | |
mbed_official | 21:b88cdeb5b302 | 87 | First, you need to select the RF driver to be used by the 6LoWPAN/Thread stack. This example supports [AT86RF233/212B](https://github.com/ARMmbed/atmel-rf-driver) and [NXP-MCR20a](https://github.com/ARMmbed/mcr20a-rf-driver) radio shields. |
Yogesh Pande |
1:e06e899acba6 | 88 | |
mbed_official | 21:b88cdeb5b302 | 89 | To add the Atmel driver to you application from command line, call: `mbed add https://github.com/ARMmbed/atmel-rf-driver`. |
mbed_official | 21:b88cdeb5b302 | 90 | Please make sure that the `mbed_app.json` file points to the correct radio driver type: |
Yogesh Pande |
1:e06e899acba6 | 91 | |
mbed_official | 21:b88cdeb5b302 | 92 | ```json |
mbed_official | 21:b88cdeb5b302 | 93 | "mesh_radio_type": { |
mbed_official | 21:b88cdeb5b302 | 94 | "help": "options are ATMEL, MCR20", |
mbed_official | 21:b88cdeb5b302 | 95 | "value": "ATMEL" |
mbed_official | 21:b88cdeb5b302 | 96 | }, |
mbed_official | 21:b88cdeb5b302 | 97 | ``` |
Yogesh Pande |
1:e06e899acba6 | 98 | |
mbed_official | 21:b88cdeb5b302 | 99 | Then you need to enable ARM IPv6/6LoWPAN stack. Edit the `mbed_app.json` file to add `NANOSTACK` feature with the particular configuration of the stack: |
Yogesh Pande |
1:e06e899acba6 | 100 | |
Yogesh Pande |
1:e06e899acba6 | 101 | ``` |
mbed_official | 21:b88cdeb5b302 | 102 | "target.features_add": ["NANOSTACK", "LOWPAN_ROUTER", "COMMON_PAL"], |
mbed_official | 21:b88cdeb5b302 | 103 | ``` |
mbed_official | 21:b88cdeb5b302 | 104 | |
mbed_official | 21:b88cdeb5b302 | 105 | If your connection type is `MESH_THREAD` then you may want to use the THREAD_ROUTER configuration: |
mbed_official | 21:b88cdeb5b302 | 106 | |
mbed_official | 21:b88cdeb5b302 | 107 | ``` |
mbed_official | 21:b88cdeb5b302 | 108 | "target.features_add": ["NANOSTACK", "THREAD_ROUTER", "COMMON_PAL"], |
Yogesh Pande |
1:e06e899acba6 | 109 | ``` |
Yogesh Pande |
1:e06e899acba6 | 110 | |
Yogesh Pande |
0:7d5ec759888b | 111 | 6LoWPAN ND and Thread use IPv6 for connectivity. Therefore, you need to verify first that you have a working IPv6 connection. To do that, ping the Connector IPv6 address `2607:f0d0:2601:52::20` from your network. |
Yogesh Pande |
0:7d5ec759888b | 112 | |
mbed_official | 21:b88cdeb5b302 | 113 | <span class="notes">**Note:** If you are using the [k64f-border-router](https://github.com/ARMmbed/k64f-border-router) (that can be used only as a 6LoWPAN BR and only with FRDM-K64F), you need to enable another security feature. By default, the `k64f-border-router` uses `PSK` as security.</span> |
mbed_official | 21:b88cdeb5b302 | 114 | |
mbed_official | 21:b88cdeb5b302 | 115 | You can enable the security here on your mbed-os-example-client application, for example: |
mbed_official | 6:8fff223f3f84 | 116 | |
mbed_official | 6:8fff223f3f84 | 117 | ```json |
mbed_official | 6:8fff223f3f84 | 118 | "target_overrides": { |
mbed_official | 6:8fff223f3f84 | 119 | "*": { |
mbed_official | 6:8fff223f3f84 | 120 | "mbed-mesh-api.6lowpan-nd-security-mode": "PSK", |
mbed_official | 6:8fff223f3f84 | 121 | } |
mbed_official | 6:8fff223f3f84 | 122 | } |
mbed_official | 6:8fff223f3f84 | 123 | ``` |
mbed_official | 21:b88cdeb5b302 | 124 | |
mbed_official | 21:b88cdeb5b302 | 125 | Alternatively, you can remove the link layer security from the `k64f-border-router`. To do that, change the [mbed_app.json](https://github.com/ARMmbed/k64f-border-router/blob/master/mbed_app.json) fetched from the `k64f-border-router` repository, for example: |
mbed_official | 6:8fff223f3f84 | 126 | |
mbed_official | 6:8fff223f3f84 | 127 | ```json |
mbed_official | 6:8fff223f3f84 | 128 | "config": { |
mbed_official | 6:8fff223f3f84 | 129 | "security-mode": "NONE", |
mbed_official | 6:8fff223f3f84 | 130 | } |
mbed_official | 6:8fff223f3f84 | 131 | ``` |

0:7d5ec759888b | 133 | #### mbed gateway |
Yogesh Pande |
0:7d5ec759888b | 134 | |
Yogesh Pande |
0:7d5ec759888b | 135 | To connect the example application in 6LoWPAN ND or Thread mode to Connector, you need to set up an mbed 6LoWPAN gateway router as follows: |
Yogesh Pande |
0:7d5ec759888b | 136 | |
Yogesh Pande |
0:7d5ec759888b | 137 | 1. Use an Ethernet cable to connect the mbed 6LoWPAN gateway router to the internet. |
Yogesh Pande |
0:7d5ec759888b | 138 | 2. Use a micro-USB cable to connect the mbed 6LoWPAN gateway router to your computer. The computer will list the router as removable storage. |
Yogesh Pande |
0:7d5ec759888b | 139 | 3. The firmware for the gateway is located in the `GW_Binary` folder in the root of this example. Select the binary matching your application bootstrap mode: |
Yogesh Pande |
0:7d5ec759888b | 140 | |
Yogesh Pande |
0:7d5ec759888b | 141 | * For the **6LoWPAN ND** bootstrap, use `gateway6LoWPANDynamic.bin`. |
Yogesh Pande |
0:7d5ec759888b | 142 | * For the **Thread** bootstrap, use `gatewayThreadDynamic.bin`. |
Yogesh Pande |
0:7d5ec759888b | 143 | |
Yogesh Pande |
0:7d5ec759888b | 144 | The dynamic binaries use IPv6 autoconfiguration and enable the client to connect to the Connector service. The static binaries create a site-local IPv6 network and packets cannot be routed outside. |
Yogesh Pande |
0:7d5ec759888b | 145 | |
Yogesh Pande |
0:7d5ec759888b | 146 | 4. Copy the gateway binary file to the mbed 6LoWPAN gateway router to flash the device. The device reboots automatically after flashing. If that does not happen, press the **Reset** button on the board. |
Yogesh Pande |
0:7d5ec759888b | 147 | |
Yogesh Pande |
0:7d5ec759888b | 148 | You can view debug traces from the gateway with a serial port monitor. The gateway uses baud rate 460800. The gateway IPv6 address is correctly configured when the following trace is visible: `Eth bootstrap ready, IP=XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX`. |
Yogesh Pande |
0:7d5ec759888b | 149 | |
Yogesh Pande |
0:7d5ec759888b | 150 | #### Channel settings |
Yogesh Pande |
0:7d5ec759888b | 151 | |
Yogesh Pande |
0:7d5ec759888b | 152 | The default 2.4GHz channel settings are already defined by the [mbed-mesh-api](https://github.com/ARMmbed/mbed-mesh-api) to match the mbed gateway settings. The application can override these settings by adding them to the `mbed_app.json` file in the main project directory. For example: |
Yogesh Pande |
0:7d5ec759888b | 153 | |
Yogesh Pande |
0:7d5ec759888b | 154 | ```json |
Yogesh Pande |
0:7d5ec759888b | 155 | "target_overrides": { |

Yogesh Pande |
0:7d5ec759888b | 164 | |
Yogesh Pande |
0:7d5ec759888b | 165 | For sub-GHz shields (AT86RF212B) use the following overrides, **6LoWPAN ND only**: |
Yogesh Pande |
0:7d5ec759888b | 166 | |
Yogesh Pande |

Yogesh Pande |
0:7d5ec759888b | 236 | |
mbed_official | 45:b150e0aa009c | 237 | This example uses IPv4 to communicate with the [mbed Device Connector Server](https://api.connector.mbed.com) except for 6LoWPAN ND and Thread. However, you can easily change it to IPv6 |
mbed_official | 45:b150e0aa009c | 238 | by changing the mbed_app.json you make: |
mbed_official | 45:b150e0aa009c | 239 | ``` |
mbed_official | 45:b150e0aa009c | 240 | "target_overrides": { |
mbed_official | 45:b150e0aa009c | 241 | "*": { |

mbed_official | 45:b150e0aa009c | 246 | } |
mbed_official | 45:b150e0aa009c | 247 | ``` |
mbed_official | 45:b150e0aa009c | 248 | by modifying the ipv4-enable or ipv6-enable to true/false. Only one should be true. |
mbed_official | 45:b150e0aa009c | 249 | |
mbed_official | 45:b150e0aa009c | 250 | The example program should automatically get an IP address from the router when connected over Ethernet or WiFi. |

mbed_official | 53:2e40e7d6aed6 | 405 | You probably have the LWIP stack in use with Ethernet or WiFi and you have the mesh RF stacks in the root of this example. You need to tell mbed NOT to compile the related files. To do that, set up a `.mbedignore` file. An example file is available in the `configs` folder. |
mbed_official | 53:2e40e7d6aed6 | 406 | |
mbed_official | 53:2e40e7d6aed6 | 407 | This should resolve the issue: |
mbed_official | 53:2e40e7d6aed6 | 408 | |
mbed_official | 52:957eff5f0ee9 | 409 | ``` |
mbed_official | 52:957eff5f0ee9 | 410 | cp configs/eth-wifi-mbedignore ./.mbedignore |
mbed_official | 52:957eff5f0ee9 | 411 | ``` |
