Light switch example not working on custom board

Hi all,

I am using segger studio , i am trying to run examples of mesh alpha sdk that nordic provides. I can able to dump the code on board successfully. But if i try to dump light switch client example on my custom board, I will not be able to get it working. I have used Bluetooth Smart BLE4.1 NRF51822-A1 module from Radioland. Please help me.


Thanks in advance.

  • OK. We suspect there might be an issue with the accuracy of the crystal oscillator used in the Radioland board. We recommend that you develop with one of the official Nordic Development kits as it makes troubleshooting easier.

    However, you could try changing the required accuracy of the crystal in firmware:

    examples/nrf_mesh_sdk.c line 191
    nrf_clock_lf_cfg_t lfc_cfg = {NRF_CLOCK_LF_SRC_XTAL, 0, 0, NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}; 

    You can find the valid defines in Infocenter.
