Softdevice S140 and SWI2 interrupt handing

Thanks for your answer. I agree with your suggestion to use the SoftDevice Hanlder library, however I could not get it to work. Now I've found out, that our application overwrites the vector-table and I forgot to add the correct irq-handler (provided by nrf_soh.h) to the SWI2. Now, after configuring it correctly it works perfectly.

Hello,

I would recommand that you use the SoftDevice Handler library (nrf_sdh.c, nrf_sdh_ble.c, nrf_sdh_soc.c ) like in our BLE example instead of polling and propagating the events yourself. The main problem with declaring your own SD_EVT_IRQHandler is that you will have implement a mechanism to forward SoC and BLE events to other SDK modules.

Best regards,
