mbed_official 21:b88cdeb5b302 21 ## Requirements for non-K64F boards
mbed_official 21:b88cdeb5b302 22
mbed_official 21:b88cdeb5b302 23 * This example requires TLS functionality to be enabled on mbed TLS.
mbed_official 21:b88cdeb5b302 24 On devices where hardware entropy is not present, TLS is disabled by default.
mbed_official 21:b88cdeb5b302 25 This would result in compile time failures or linking failures.
mbed_official 7:9a1ee269650b 26
mbed_official 21:b88cdeb5b302 27 To learn why entropy is required, read the
mbed_official 21:b88cdeb5b302 28 [TLS Porting guide](https://docs.mbed.com/docs/mbed-os-handbook/en/5.2/advanced/tls_porting/).
mbed_official 21:b88cdeb5b302 29
mbed_official 21:b88cdeb5b302 30 * On non-K64F boards, there is no unregistration functionality and
mbed_official 21:b88cdeb5b302 31 button presses are simulated through timer ticks incrementing every 15 seconds.
mbed_official 7:9a1ee269650b 32
Yogesh Pande 0:7d5ec759888b 33 ## Required software
Yogesh Pande 0:7d5ec759888b 34
Yogesh Pande 0:7d5ec759888b 35 * [ARM mbed account](https://developer.mbed.org/account/login/?next=/).
Yogesh Pande 0:7d5ec759888b 36 * [mbed-cli](https://github.com/ARMmbed/mbed-cli) - to build the example programs. To learn how to build mbed OS applications with mbed-cli, see [the user guide](https://github.com/ARMmbed/mbed-cli/blob/master/README.md).
Yogesh Pande 0:7d5ec759888b 37 * [Serial port monitor](https://developer.mbed.org/handbook/SerialPC#host-interface-and-terminal-applications).
Yogesh Pande 0:7d5ec759888b 38
Yogesh Pande 0:7d5ec759888b 39 ## Application setup
Yogesh Pande 0:7d5ec759888b 40
mbed_official 21:b88cdeb5b302 41 To configure the example application:
Yogesh Pande 0:7d5ec759888b 42
Yogesh Pande 0:7d5ec759888b 43 1. [Select the connection type](#connection-type).
Yogesh Pande 0:7d5ec759888b 44 1. [Set the client credentials](#client-credentials).
Yogesh Pande 0:7d5ec759888b 45 1. [Change 6LoWPAN ND & Thread settings](#6lowpan-nd-and-thread-settings).

Yogesh Pande 0:7d5ec759888b 48 1. [Set up an IP address](#ip-address-setup). This step is optional.
Yogesh Pande 0:7d5ec759888b 49 1. [Change the socket type](#changing-socket-type). This step is optional.
Yogesh Pande 0:7d5ec759888b 50
Yogesh Pande 0:7d5ec759888b 51 ### Connection type
Yogesh Pande 0:7d5ec759888b 52
Yogesh Pande 0:7d5ec759888b 53 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 54
Yogesh Pande 0:7d5ec759888b 55 ```json
Yogesh Pande 0:7d5ec759888b 56 "network-interface": {
Yogesh Pande 0:7d5ec759888b 57 "help": "options are ETHERNET,WIFI,MESH_LOWPAN_ND,MESH_THREAD.",
Yogesh Pande 0:7d5ec759888b 58 "value": "MESH_LOWPAN_ND"
Yogesh Pande 0:7d5ec759888b 59 }
Yogesh Pande 0:7d5ec759888b 60 ```
Yogesh Pande 0:7d5ec759888b 61
Yogesh Pande 0:7d5ec759888b 62 ### Client credentials
Yogesh Pande 0:7d5ec759888b 63
mbed_official 21:b88cdeb5b302 64 To register the application with the Connector service, you need to create and set the client side certificate.
Yogesh Pande 0:7d5ec759888b 65
Yogesh Pande 0:7d5ec759888b 66 1. Go to [mbed Device Connector](https://connector.mbed.com) and log in with your mbed account.
mbed_official 21:b88cdeb5b302 67 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 68 1. Replace the contents in the `security.h` file of this project's directory with the content copied above.
Yogesh Pande 0:7d5ec759888b 69
Yogesh Pande 0:7d5ec759888b 70 ### 6LoWPAN ND and Thread settings
Yogesh Pande 0:7d5ec759888b 71
mbed_official 21:b88cdeb5b302 72 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 73
mbed_official 21:b88cdeb5b302 74 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 75 Please make sure that the `mbed_app.json` file points to the correct radio driver type:
Yogesh Pande 1:e06e899acba6 76
mbed_official 21:b88cdeb5b302 77 ```json
mbed_official 21:b88cdeb5b302 78 "mesh_radio_type": {
mbed_official 21:b88cdeb5b302 79 "help": "options are ATMEL, MCR20",
mbed_official 21:b88cdeb5b302 80 "value": "ATMEL"
mbed_official 21:b88cdeb5b302 81 },
mbed_official 21:b88cdeb5b302 82 ```
Yogesh Pande 1:e06e899acba6 83
mbed_official 21:b88cdeb5b302 84 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 85
Yogesh Pande 1:e06e899acba6 86 ```
mbed_official 21:b88cdeb5b302 87 "target.features_add": ["NANOSTACK", "LOWPAN_ROUTER", "COMMON_PAL"],
mbed_official 21:b88cdeb5b302 88 ```
mbed_official 21:b88cdeb5b302 89
mbed_official 21:b88cdeb5b302 90 If your connection type is `MESH_THREAD` then you may want to use the THREAD_ROUTER configuration:
mbed_official 21:b88cdeb5b302 91
mbed_official 21:b88cdeb5b302 92 ```
mbed_official 21:b88cdeb5b302 93 "target.features_add": ["NANOSTACK", "THREAD_ROUTER", "COMMON_PAL"],
Yogesh Pande 1:e06e899acba6 94 ```
Yogesh Pande 1:e06e899acba6 95
Yogesh Pande 0:7d5ec759888b 96 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 97
mbed_official 21:b88cdeb5b302 98 <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 99
mbed_official 21:b88cdeb5b302 100 You can enable the security here on your mbed-os-example-client application, for example:
mbed_official 6:8fff223f3f84 101
mbed_official 6:8fff223f3f84 102 ```json
mbed_official 6:8fff223f3f84 103 "target_overrides": {
mbed_official 6:8fff223f3f84 104 "*": {
mbed_official 6:8fff223f3f84 105 "mbed-mesh-api.6lowpan-nd-security-mode": "PSK",
mbed_official 6:8fff223f3f84 106 }
mbed_official 6:8fff223f3f84 107 }
mbed_official 6:8fff223f3f84 108 ```
mbed_official 21:b88cdeb5b302 109
mbed_official 21:b88cdeb5b302 110 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 111
mbed_official 6:8fff223f3f84 112 ```json
mbed_official 6:8fff223f3f84 113 "config": {
mbed_official 6:8fff223f3f84 114 "security-mode": "NONE",
mbed_official 6:8fff223f3f84 115 }
mbed_official 6:8fff223f3f84 116 ```
mbed_official 21:b88cdeb5b302 117
Yogesh Pande 0:7d5ec759888b 118 #### mbed gateway
Yogesh Pande 0:7d5ec759888b 119
Yogesh Pande 0:7d5ec759888b 120 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 121
Yogesh Pande 0:7d5ec759888b 122 1. Use an Ethernet cable to connect the mbed 6LoWPAN gateway router to the internet.
Yogesh Pande 0:7d5ec759888b 123 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 124 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 125
Yogesh Pande 0:7d5ec759888b 126 * For the **6LoWPAN ND** bootstrap, use `gateway6LoWPANDynamic.bin`.
Yogesh Pande 0:7d5ec759888b 127 * For the **Thread** bootstrap, use `gatewayThreadDynamic.bin`.
Yogesh Pande 0:7d5ec759888b 128
Yogesh Pande 0:7d5ec759888b 129 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 130
Yogesh Pande 0:7d5ec759888b 131 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 132
Yogesh Pande 0:7d5ec759888b 133 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 134
Yogesh Pande 0:7d5ec759888b 135 #### Channel settings
Yogesh Pande 0:7d5ec759888b 136
Yogesh Pande 0:7d5ec759888b 137 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 138
Yogesh Pande 0:7d5ec759888b 139 ```json
Yogesh Pande 0:7d5ec759888b 140 "target_overrides": {
Yogesh Pande 0:7d5ec759888b 141 "*": {
Yogesh Pande 0:7d5ec759888b 142 "mbed-mesh-api.6lowpan-nd-channel-page": 0,
Yogesh Pande 0:7d5ec759888b 143 "mbed-mesh-api.6lowpan-nd-channel": 12,
Yogesh Pande 0:7d5ec759888b 144 "mbed-mesh-api.thread-config-channel-page": 0,
Yogesh Pande 0:7d5ec759888b 145 "mbed-mesh-api.thread-config-channel": 12
Yogesh Pande 0:7d5ec759888b 146 }
Yogesh Pande 0:7d5ec759888b 147 }
Yogesh Pande 0:7d5ec759888b 148 ```
Yogesh Pande 0:7d5ec759888b 149
Yogesh Pande 0:7d5ec759888b 150 For sub-GHz shields (AT86RF212B) use the following overrides, **6LoWPAN ND only**:
Yogesh Pande 0:7d5ec759888b 151
Yogesh Pande 0:7d5ec759888b 152 ```json
Yogesh Pande 0:7d5ec759888b 153 "mbed-mesh-api.6lowpan-nd-channel-page": 2,
Yogesh Pande 0:7d5ec759888b 154 "mbed-mesh-api.6lowpan-nd-channel": 1
Yogesh Pande 0:7d5ec759888b 155 ```
Yogesh Pande 0:7d5ec759888b 156
mbed_official 21:b88cdeb5b302 157 For more information about the radio shields, see [the related documentation](docs/radio_module_identify.md). All configurable settings can be found in the `mbed-os-example-client/mbed-os/features/FEATURE_IPV6/mbed-mesh-api/mbed_lib.json` file.
Yogesh Pande 0:7d5ec759888b 158
Yogesh Pande 0:7d5ec759888b 159 #### Thread-specific settings
Yogesh Pande 0:7d5ec759888b 160
Yogesh Pande 0:7d5ec759888b 161 With Thread, you can change the operating mode of the client from the default router mode to a sleepy end device by adding the following override to the `mbed_app.json` file:
Yogesh Pande 0:7d5ec759888b 162
Yogesh Pande 0:7d5ec759888b 163 ```json
Yogesh Pande 0:7d5ec759888b 164 "mbed-mesh-api.thread-device-type": "MESH_DEVICE_TYPE_THREAD_SLEEPY_END_DEVICE"
Yogesh Pande 0:7d5ec759888b 165 ```
Yogesh Pande 0:7d5ec759888b 166
Yogesh Pande 0:7d5ec759888b 167 ### Ethernet settings

Yogesh Pande 0:7d5ec759888b 221
Yogesh Pande 0:7d5ec759888b 222 This example uses IPv4 to communicate with the [mbed Device Connector Server](https://api.connector.mbed.com) except for 6LoWPAN ND and Thread. The example program should automatically get an IPv4 address from the router when connected over Ethernet.
Yogesh Pande 0:7d5ec759888b 223
Yogesh Pande 0:7d5ec759888b 224 If your network does not have DHCP enabled, you have to manually assign a static IP address to the board. We recommend having DHCP enabled to make everything run smoothly.
