I have read that at each connection event master will send the first packet (empty payload).
In a case where slave latency > 1, the slave will not be listening to master...
Hi devs,
It is not a real issue it is about a possible misconception about app_timer
For my application, I am using multiples timers using app_timer_create. From my understanding...
