Scenario is as follows: NRF52 (SDK12.1, SD3.0) works in central and peripheral mode.
What happens is that on start we create a single shot timer with 4.2second to wait for external device being activated on UART. For some reason if central->peripheral connection starts right away timeout handler doesnt get executed. If central->peripheral link gets created later the first timer event works out fine, but after connection is made all timers dont work anymore.
I also dont get any errors. Any advices where to dig? Thanks!
