ble_advertising_advdata_update() giving error when called inside radio notification

[Ameer Usman]

I am calling my advertising update inside:

void SWI1_IRQHandler(bool radio_evt)
{
.....


}

And my advertising update gives an error, otherwise if I use inside a timer it works fine.

Hi,

Have you changed the default interrupt priority for the SWI1_IRQn? It's '6'/APP_IRQ_PRIORITY_LOW by default.

[Ameer Usman]

No I did not change it. Should I change it to another value? If yes then from where can I do that.

[Vidar Berg]

It's recommended to use the default interrupt priority. The reason I asked about the interrupt priority is that SD APIs will lead to a hardfault exception if called from an interrupt with higher priority than the SVC itself. Can you post the code you used to set up radio notifications? Also, are you able to describe what the error is?

[Ameer Usman]

I believe the issue lied within the interrupt priority, so I raised a flag in the SWI1_IRQHandler() and in the while loop which would perform the advertising update and it works fine.
