Ok, but does lib_state->startStack() return, or is there some loop inside it that prevents the application from terminating?

The app_init() function uses application libirary and this lib_state->startStack() starts stack protocol and I am sure both these things don't use timer.

The softdevice will not help you with your issue, it is the BLE stack and is used for BLE stuff. I was asking, since it occupies TIMER0, and you are using TIMER0 to do the SAADC sampling in your application.

Is there some kind of loop in your program that prevents the CPU from executing random instructions after you initialize the SAADC? What happens in lib_state->startStack()? Where is App_init() called from?

hi jorgen,

_send_data() function send data to sink node.Yes I have check all function returns NRF_SUCCESS. Please tell me how softdevice will help me and how to use it.

Hi,

I'm not sure what the _send_data() function does, but do you check that all function calls return NRF_SUCCESS?

You are not using the softdevice in your application? The softdevice uses TIMER0 and blocks access to this instance from the application.

Best regards,
Jørgen
