When I get the SD Assertion at address 0x25252 (SD140 V6.1.0 SDK 15.2.0)

Hi,

can you please tell me in what cases I get this assertion?

SOFTDEVICE: ASSERTION FAILED, PCxxx: 0x25252

For background:
 using the timeslot API works for about 50 times which end a wanted sequence.
When I want to request the first timeslot for the next sequence some ms later I got once or twice a response 15 (NRF_ERROR_FORBIDDEN)
and 2 ms later I got the assertion. Since I didn't got a positive response I didn't use the timeslot at that time.

With SD V6.1.1 the assertion address is: 0x251ba

Thank you in advance

I can find that this assert occurs if the application used too much time in the callback handler. Softdevice timing may be thrown off.

Hi Kenneth,

thank you for your fast answer.

That is possible, but I have to look a little deeper in it, and will close the ticket if it is the case.

Best regards,

Hi Kenneth,

this was the thing, too  much debug outputs in the callback handler to find out another problem.

Thank you again,

Dirk
