I'm trying to get the ble_app_blinky example from the NRF5 Thread SDK working on the Adafruit Feather nRF52840 Sense using the S140 soft device v. 7.0.1 I'm compiling the example successfully on an Ubuntu computer and flashing it to the board successfully, but it doesn't work. I have debugging working over a serial port through a CP2104 board, but get no error or warning messages (logging is turned on for all modules at the error and warning levels in the SDK). Using my own log messages, I've determined that ble_stack_init() doesn't return. Tracing the problem down, ble_stack_init() calls nrf_sdh_ble_enable(&ram_start), which calls sd_ble_enable(p_app_ram_start), which doesn't return. Does anyone have experience with a problem like this or any idea as to what might be causing the function to not return with no error message?
