My kit is a nRF52840 PDK, i've installed SDK_14.2.0 and succesfully built and flashed the ble_app_hrs example project, but i'm not able to work as expected with the debugger.
Below the details on my setup,
Any help is welcome!

If I set a breakpoint, for example:
b ble_stack_init
I have two cases:
Case 1
(gdb) b ble_stack_init
Breakpoint 1 at 0x286fa: file ../../../main.c, line 863.
(gdb) c
Continuing.
Program received signal SIGTRAP, Trace/breakpoint trap.

What is it needed to go ahead?
