Hi
I am trying to use the serial library with IRQ and callback function, but the event NRF_SERIAL_EVENT_RX_DATA is never triggered. No other event than NRF_SERIAL_EVENT_TX_DONE is passed to the callback function. I'm aware of a similar case, https://devzone.nordicsemi.com/f/nordic-q-a/37270/nrf_serial_event_rx_data-never-triggered, but reducing the amount of code in the interrupt handler didn't work for me.
I'm using SDK15.2
this is the setup:
and the initialization:
and the callback function:
Setting a breakpoint at line 6 or line 13 never triggers.
Data sent (blue) and received (red) look fine
Any suggestion on how to proceed?
