The accelerometer values...
For a device that has APPROTECT enabled, it is required to use nrfjprog --recover to re-enable access.
What is the mechanism that nrfjprog uses to perform the --recover...
With the nRF52, is the RTT functional when APPROTECT is enabled?
I would expect not since the RTT relies on memory accesses which should be disabled with APPROTECT
Hi,
In SDK11, it was possible to call app_sched_execute() from a function that was itself called from the scheduler:
void app_sched_execute(void)
{
void * p_event_data;...
