This example duplicates the functionalities of the SDK example - soc-btmesh-switch with NCP mode, instead of controlling the light by the push buttons on the WSTK, it implements a lightweight console, so that you can use the CLI to control the lights in the network. For more information about the ncp mode and ncp host and target, please go through KBA_BT_1602: NCP Host Implementation and Example.

Hardware & SDK Requirements

• IDE – Simplicity Studio 4
• SDK – Bluetooth Mesh SDK 1.4.0 GA or newer, the latest version is always recommended.
• NCP target – At least 1 Bluetooth Mesh compatible boards - EFR32xG12, EFR32xG13 or EFR32xG21 (x= M, B) based, SLWRB4104A and SLWRB4103A are recommended.
• NCP host - POSIX compatible machine to run the host application. Running the application on Windows needs some porting afford, this has only been tested with Linux and Cygwin.

How to Use It

The NCP mode requires both the host and target to work.

Supported Commands

A simple console is implemented to receive commands from user. Users can add any customized command by adding an new item to CMDs array in app.c.

Generate NCP target

1. Create "NCP - Mesh Empty Target" project based on the attached board and the latest Bluetooth Mesh SDK.
2. Open the ${projectname}.isc file, add "Light Lightness Client", "Generic Power OnOff Client" and "Light CTL Client" models to the Bluetooth SIG Models section. It's recommended to delete "Configuration Client" and "Generic OnOff Server" models from it. Modify the _Features Bitmask to 0x000b, then click "Generate" button.
3. If the NCP target needs to sleep, you need to make step 4-5 changes to the project. The provided example DOESN'T enable the sleep mode.
4. Add below code right before while(1) in main.c:

#if defined(_SILICON_LABS_32B_SERIES_1_CONFIG_3)
  /* xG13 devices have two RTCCs, one for the stack and another for the application.
     * The clock for RTCC needs to be enabled in application code. In xG12 RTCC init
     * is handled by the stack */
  CMU_ClockEnable(cmuClock_RTCC, true);
#endif

1. Open the hal-config.h file and define the symbol NCP_DEEP_SLEEP_ENABLED. After that, you need to specify the wake up pin location to the symbols NCP_WAKEUP_PORT, NCP_WAKEUP_PIN and NCP_WAKEUP_POLARITY. The same rule applies to the symbol NCP_HOST_WAKEUP_ENABLED if you want the NCP target could wakeup the host.
2. Erase the attached board, then build and program to it.

Run the example

• Download the attachment and extract it.
• cd to the foler and run "make SDK_DIR=xxx", where xxx is the real directory of your BT Mesh SDK. Assuming it builds without errors.
• The executable takes 2 parameters - serial port and baud rate. Run it as "sudo ./exe/switch /dev/ttyACM2 115200"
• If the shell starts normally, type "h" to get usage example
• Find a provisioner and light node to test it.
