SDK UART coexistence example

The mesh part of this example implements the Light Switch Client example in nRF5 SDK for Mesh.

The BLE part of the example is identical to the ble_app_uart example in the nRF5 SDK except for the following changes:

• The BSP events SLEEP, DISCONNECT and WHITELIST_OFF are ignored. This makes the board buttons only control the mesh part of the application.
• The advertising interval is increased to allow more time for the mesh stack.
• The Light Switch servers can be controlled both over BLE and UART by sending the Light Switch Client button number to be simulated.

The example is intended to replace the Light Switch Client when running the Light Switch example.

Setting up the example

• Copy the ble_app_uart_coexist folder into your nRF5 SDK installation's examples\ble_peripheral folder
• Open the Segger Embedded Studio project at ble_app_uart_coexist\pca10040\s132\ses\ble_app_uart_pca10040_s132.emProject.
• Add MESH_ROOT to your Segger Embedded Studio global macro list. — From SES menu bar, click 'Tools' -> 'Options...' — In left column, click 'Building' — In right column, double click 'Global macros' — Add your mesh root directory on a new line. MESH_ROOT=<path to your mesh installation>

Running the example

• Program the Light Switch example devices as described in the Light switch demo, except for replacing the Light Switch Client with examples\ble_peripheral\ble_app_uart_coexist\pca10040\s132\ses\Output\Release\Exe\ble_app_uart_pca10040_s132.hex.
• Run the two coexisting examples in parallel or in sequence:
  • Run the Light Switch example as described in Light switch demo.
  • Run the ble_app_uart example as described in the nRF5 SDK documentation.
    • Write the hexadecimal ascii codes equivalent to one of the digits (1, 2, 3, or 4) in the UART RX characteristic to simulate a button press.
