How for the the nrf53 application processor to verify the network processor is active on BLE?

[Jordan Archer]

I have some odd cases where an nrf53 based device just disappears from BLE.  It's no longer connected, and not advertising.

I'm looking for a method for the application processor to verify that the network processor is running.  And it's current BLE state.

Hi

I just wanted to let you know that I have asked internally on what this could be and if it's possible to monitor the network core somehow and I'm waiting for a reply. If you have any more details on what's happening when the device disappears that might help us narrowing down the issue as well. Does it only happen when the device is advertising or only when it is connected, or can it happen in any state for example?

Best regards,

Simon
