Hello
I'm working on SDK v17, and I'm using the nRF52832 custom board.
I use several APP_TIMERs. One of those timers doesn't seem to be working properly. Timer calls are being made, but the LED is not output.
This timer will be toggled repeatedly during Bluetooth advertising. When Bluetooth is paired, the timer must be shut down and the LED should be on.
Firmware test completed successfully with nRF52DK. And through the example of Blinky, I have confirmed that the LED is working.
Debugging also does not print errors.

It's my first time use with a custom board, so it's hard to find a problem. Is this a possible hardware issue?
Thank you.
