Calling fds_record_update() in ISR

[beemavishnu]

Hello,

 

I am using nRF52840, SDK_16.0.0, SoftDevice S140 V7.0.1 and Segger for flashing the image. I am using ‘ble_app_blinky’.

 

Whether can I call fds_record_update() in ISR (Ex: Calling within Uart interrupt / Even handler) or do I need to set a variable in ISR and in idle_state_handle() do I need to update FDS by checking the variable set in ISR.

 

Thanks & Regards

Hi,

This depends on the interrupt priority of the ISR you want to call the FDS api, typically it will work to call FDS from interrupt priority 5, 6 and 7:

For higher ISR priorities you should use a flag in the ISR and instead call it from main() yes.
