bluetooth supervision timeout help

[jon]

Is there a way to get the supervision timeout counter from the peripheral side? I am currently working with nRF5X modules and starting with the nordic uart example from the SDK. I currently have a log for the connection parameters, but would like to have a log to show this timer value somehow.

Supervision timeout is feature of BLE stack (Link Layer), it has nothing to do with module or HW. So you should speak about stack you use first. Assuming that it's Nordic Soft Device then the answer is no, it doesn't provide such internal details of LL through the API to higher layers. If you insist on it then you need to go with other stack which either has it or is open source and you can write this little feature to it. Or develop your won stack of course (but I guess that's not how you want to spend next year of your life;).
