softdevice assert fault handler

[Bert Thomas]

Hi all,

The project I am working on consists of a BLE peripheral, a BLE central and an enhanced shockburst device. I run into a problem in the code of the peripheral: the softdevice assert handler is invoked. PC = 98638 (0x1814E), id=1, info=0.

This happens rather consistently after a few seconds when the battery of the central is removed. If the central goes to sleep everything keeps working.

I suspect it has something to do with the timeslot API requirements. If I disable the ESB stuff the problem doesn't occur anymore. Can you provide me the reason for the assert?

I'm using softdevice S112 v 6.1.0 on a nrf52810.

Kind regards,

Bert

Hi Bert,

You are seeing a bug in the SoftDevice. The workaround is to change the RADIO interrupt priority to 0 in the ESB library (radio_irq_priority).
