I try to integrate the ble peripheral uart example and the beaconing mesh example. It build completed. But when i build and debug on nrf52 board. I have some errors about funtion "SVCALL(SD_BLE_CFG_SET, uint32_t, sd_ble_cfg_set(uint32_t cfg_id, ble_cfg_t const * p_cfg, uint32_t app_ram_base));" return "Unknow error".
Anyone has the solution to this problem? please help me. Thanks all!
