I use an app_timer to periodically update sensor reading in my application. There is a characteristic used to change updating rate by stopping and restarting the app_timer:
app_timer_stop(m_our_char_timer_id);
app_timer_start(m_our_char_timer_id, APP_TIMER_TICKS(1000, APP_TIMER_PRESCALER), NULL); //1000ms
It works fine with SDK11. But with SDK12, I couldn't receive any data package after stopping and restarting the app_timer. Weird thing is, usually after 5 to 6 minutes, it resumes updating again.
Any help is appreciated. Thanks.
