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. |

0:7d5ec759888b | 48 | |
mbed_official | 76:29e676124b6c | 49 | ### Mesh |
mbed_official | 76:29e676124b6c | 50 | |
mbed_official | 77:e0618756b84e | 51 | There are example settings under the configs directory, which provide the easiest way to start with the applications. |
mbed_official | 77:e0618756b84e | 52 | The [mbed-mesh-api](https://github.com/ARMmbed/mbed-os/tree/master/features/nanostack/FEATURE_NANOSTACK/mbed-mesh-api/mbed_lib.json) |

Yogesh Pande |
0:7d5ec759888b | 61 | |
mbed_official | 76:29e676124b6c | 62 | First, you need to select the RF driver to be used by the 6LoWPAN/Thread stack. |
mbed_official | 76:29e676124b6c | 63 | |
mbed_official | 76:29e676124b6c | 64 | This example supports these shields: |
Yogesh Pande |
0:7d5ec759888b | 65 | |
mbed_official | 76:29e676124b6c | 66 | * [AT86RF233/212B](https://github.com/ARMmbed/atmel-rf-driver) |
mbed_official | 76:29e676124b6c | 67 | * [NXP-MCR20a](https://github.com/ARMmbed/mcr20a-rf-driver) |
mbed_official | 76:29e676124b6c | 68 | * [X-NUCLEO-IDS01A4](https://github.com/ARMmbed/stm-spirit1-rf-driver) (*a.k.a.* Spirit1) radio shields. Check instructions for compilation [here](#compile-configuration-for-spirit1) |
Yogesh Pande |
0:7d5ec759888b | 69 | |
mbed_official | 76:29e676124b6c | 70 | To select the radio shield make sure that the `mbed_app.json` file points to the correct radio driver type: |
Yogesh Pande |
1:e06e899acba6 | 71 | |
mbed_official | 21:b88cdeb5b302 | 72 | ```json |
mbed_official | 21:b88cdeb5b302 | 73 | "mesh_radio_type": { |
mbed_official | 76:29e676124b6c | 74 | "help": "options are ATMEL, MCR20, SPIRIT1", |
mbed_official | 76:29e676124b6c | 75 | "value": "ATMEL" |
mbed_official | 21:b88cdeb5b302 | 76 | }, |
mbed_official | 21:b88cdeb5b302 | 77 | ``` |
Yogesh Pande |
1:e06e899acba6 | 78 | |
mbed_official | 21:b88cdeb5b302 | 79 | 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 | 80 | |
Yogesh Pande |
1:e06e899acba6 | 81 | ``` |
mbed_official | 21:b88cdeb5b302 | 82 | "target.features_add": ["NANOSTACK", "LOWPAN_ROUTER", "COMMON_PAL"], |
mbed_official | 21:b88cdeb5b302 | 83 | ``` |
mbed_official | 21:b88cdeb5b302 | 84 | |
mbed_official | 76:29e676124b6c | 85 | If your connection type is `MESH_THREAD` then you may want to use the `THREAD_ROUTER` configuration: |
mbed_official | 21:b88cdeb5b302 | 86 | |
mbed_official | 21:b88cdeb5b302 | 87 | ``` |
mbed_official | 21:b88cdeb5b302 | 88 | "target.features_add": ["NANOSTACK", "THREAD_ROUTER", "COMMON_PAL"], |
Yogesh Pande |
1:e06e899acba6 | 89 | ``` |
Yogesh Pande |
1:e06e899acba6 | 90 | |
mbed_official | 76:29e676124b6c | 91 | Since 6LoWPAN ND and Thread use IPv6 for connectivity, you need to verify first that you have a working IPv6 connection. |
mbed_official | 76:29e676124b6c | 92 | To do that, ping the Connector IPv6 address `2607:f0d0:2601:52::20` from your network. |

mbed_official | 76:29e676124b6c | 94 | #### Compile configuration for Spirit1 |
mbed_official | 76:29e676124b6c | 95 | |
mbed_official | 76:29e676124b6c | 96 | <span class="notes">**Note:** In case you want to use the STM Spirit1 Sub-1 GHz RF expansion board (X-NUCLEO-IDS01A4), you also need to configure its MAC address in the `mbed_app.json` file, for example:</span> |
mbed_official | 72:d0c254f237c4 | 97 | |
mbed_official | 72:d0c254f237c4 | 98 | ```json |

mbed_official | 72:d0c254f237c4 | 103 | } |
mbed_official | 72:d0c254f237c4 | 104 | ``` |
mbed_official | 72:d0c254f237c4 | 105 | |
mbed_official | 77:e0618756b84e | 106 | #### Channel settings |
mbed_official | 77:e0618756b84e | 107 | |
mbed_official | 91:60ecc29f2ba1 | 108 | The default 2.4GHz channel settings are already defined by the [mbed-mesh-api](https://github.com/ARMmbed/mbed-os/tree/master/features/nanostack/FEATURE_NANOSTACK/mbed-mesh-api) to match the Border Router settings. The application can override these settings by adding them to the `.json` file. For example: |
mbed_official | 77:e0618756b84e | 109 | |
mbed_official | 77:e0618756b84e | 110 | ```json |
mbed_official | 77:e0618756b84e | 111 | "target_overrides": { |

mbed_official | 77:e0618756b84e | 118 | } |
mbed_official | 77:e0618756b84e | 119 | ``` |
mbed_official | 77:e0618756b84e | 120 | |
mbed_official | 77:e0618756b84e | 121 | For sub-GHz shields ([Spirit1](https://github.com/ARMmbed/stm-spirit1-rf-driver) or AT86RF212B) use the following overrides, **6LoWPAN ND only**: |
mbed_official | 77:e0618756b84e | 122 | |
mbed_official | 77:e0618756b84e | 123 | ```json |
mbed_official | 77:e0618756b84e | 124 | "mbed-mesh-api.6lowpan-nd-channel-page": 2, |
mbed_official | 77:e0618756b84e | 125 | "mbed-mesh-api.6lowpan-nd-channel": 1 |

mbed_official | 76:29e676124b6c | 202 | #### Compile configuration for ODIN WiFi |
mbed_official | 76:29e676124b6c | 203 | |
mbed_official | 76:29e676124b6c | 204 | To compile ODIN WiFi configuration, 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 | 76:29e676124b6c | 205 | |
mbed_official | 76:29e676124b6c | 206 | This should resolve the issue: |
mbed_official | 76:29e676124b6c | 207 | |
mbed_official | 76:29e676124b6c | 208 | ``` |
mbed_official | 76:29e676124b6c | 209 | cp configs/eth-wifi-mbedignore ./.mbedignore |

mbed_official | 76:29e676124b6c | 211 | |
mbed_official | 76:29e676124b6c | 212 | ### Non listed board support |
mbed_official | 76:29e676124b6c | 213 | |
mbed_official | 76:29e676124b6c | 214 | Apart from the listed configurations, 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. On devices where hardware entropy is not present, TLS is disabled by default. This would result in compile time failures or linking failures. |
mbed_official | 76:29e676124b6c | 215 | |
mbed_official | 76:29e676124b6c | 216 | To learn why entropy is required, read the [TLS Porting guide](https://docs.mbed.com/docs/mbed-os-handbook/en/5.2/advanced/tls_porting/). |
mbed_official | 76:29e676124b6c | 217 | |
mbed_official | 76:29e676124b6c | 218 | Also, the complete example configuration of mbed Client, the selected network interface and mbed OS components must fit into hardware's given memory size (Flash size and RAM size). |

Yogesh Pande |
0:7d5ec759888b | 234 | |
mbed_official | 68:1a8e13b21e7e | 235 | 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 by changing the `mbed_app.json` you make: |
mbed_official | 76:29e676124b6c | 236 | |
mbed_official | 45:b150e0aa009c | 237 | ``` |
mbed_official | 45:b150e0aa009c | 238 | "target_overrides": { |
mbed_official | 45:b150e0aa009c | 239 | "*": { |

mbed_official | 45:b150e0aa009c | 242 | "lwip.ipv6-enabled": true, |
mbed_official | 45:b150e0aa009c | 243 | "mbed-trace.enable": 0 |
mbed_official | 45:b150e0aa009c | 244 | } |
mbed_official | 45:b150e0aa009c | 245 | ``` |
mbed_official | 76:29e676124b6c | 246 | |
mbed_official | 68:1a8e13b21e7e | 247 | by modifying the `ipv4-enabled` or `ipv6-enabled` to `true/false`. Only one should be true. |
mbed_official | 45:b150e0aa009c | 248 | |
mbed_official | 45:b150e0aa009c | 249 | The example program should automatically get an IP address from the router when connected over Ethernet or WiFi. |
