RE: Fast Advertising Timeout Units

Hello,

I got distracted for a while by other things, but in finally swinging back to this effort, I tried your suggested ble_app_hrs example without also upgrading the SDK and the fast advertising internal seems much more accurate. So the issue appears to be in my application. I will poke around with that and see what I can find.

Thank you!

Hi Mkruger,
I just did a test here with the nRF52840 with ble_app_hrs in SDK v15.3.

The example configured ble_adv_fast_timeout =18000 and it seems the timeout was right. I observed that it stopped after 3 minutes sharp. The device enter SystemOFF mode after that.

Could you try to test with the sample (and SDK v15.3)? Please make sure the advertising was not restarted for example because of other central connect to it.
Has the difference consistent ? There could be a chance that the LFCLK was drifting. But it doesn't explain how the ble_adv_slow_timeout still correct. From what I can see in the code it's identical how the ble_adv_slow_timeout and ble_adv_fast_timeout is used.
