Softdevice assert 151994:0

[HAFLN]

I am getting an intermittent "Softdevice assert: 151994:0" error on device initialisation or after the device has run for a period of time. I am using Light Switch Client stock example.

Nordic SDK: nRF5_SDK_15.3.0_59ac345

Nordic Mesh SDK:  nrf5_SDK_for_Mesh_v3.2.0_src

Softdevice: s140_nrf52_6.1.1_softdevice.hex

The device is custom, built on MDBT50Q. 

Sample error log output:

1. <t: 12895576>, app_error_weak.c, 96, Softdevice assert: 151994:0
2. <t: 74659>, app_error_weak.c, 96, Softdevice assert: 151994:0
3. <t: 74453>, app_error_weak.c, 96, Softdevice assert: 151994:0
4. <t: 74629>, app_error_weak.c, 96, Softdevice assert: 151994:0

Hi.

Are you able to provide any more information about the assert?

I suspect that you might have spent too much time in the radio timeslot. From the SDS, see: Ending a timeslot in time,
"The application is responsible for keeping track of timing within the Radio Timeslot and for ensuring that the application’s use of the peripherals does not last for longer than the granted timeslot length."

Best regards,
