Timer0 interrupt blocked by Radio interrupt

Guenther

Hello support team,

If a message is received while the timer0 is running and the radio interrupt is enabled, the Radio interrupt hits and disables the timer interrupt. There seams to be a conflict between these 2 interrupts.

    The ARM processor has interrupt priorities and it sounds like the radio interrupt is set to have a higher priority than timer0. You can read up on how the NVIC works on the ARM here:

    ARM NVIC doc

    Note, I am assuming that you are not running the soft device stack as it blocks timer0. The soft device stack imposes restrictions on what you can set the application interrupt priorities to. You can read more about that in the soft device stack product specification.
