DanaRS pump: Re-pair needed after change from 26.02.2023

[Alamo04]

Before that change I only needed to pair my DanaRS once, after I get the pump over one year ago.

Now I had to re-pair my pump two times in 5 days again, last time this morning while sleeping.

Please remove this change, its annoying: https://github.com/nightscout/AndroidAPS/commit/1fa2cb937095647843ef9febdc344b26fb6133a9

I can confirm that I had that too a couple of times. But not as often as on your setup. But it happened to me. During that time I had no pump replacement or so, it just happened during normal operation.

@MilosKozak Re-pairing was as followed:

[Alamo04]

Done, will report if it comes up again.

Will test it for a week, because I had that issue twice in 5 days.

@MilosKozak Just now happend again on workplace.

[MilosKozak]

provide logs

Think, a better way will be to deactivate Bluetooth wait 5 seconds and activate BT again. Normaly the pump connects again then and no new pairing is needed. My display on the pump has some scratches, so its hard to read all characters if new pairing is needed. Especially in darker environment.

[MilosKozak]

turning off BT adapter is not possible with Android 13 already. The code will be removed

[MilosKozak]

sorry, but the problem is between phone and pump. On your place I'd try different phone first Sadly Dana pumps don't have a way to check if encryptions keys are ok. Pump simply doesn't respond. Thus reaction of AAPS to not responding pump (after some attempts) is clearing the encryption keys

[Alamo04]

The system works fine before that change, only sometimes (after 5 days today) the connection was lost and then I got an alarm, restart BT and everything was fine again.

Can't we stay with that ? Don't need a new pairing in that case, ist's a lot faster to de-/activate BT.

Pixel5, DanaRS, AAPS latest, Boyda

[MilosKozak]

previous solution had another issues

[Alamo04]

Changed to Dana-i (don't like that pump) and no re-pair comes up for the lat 7 days. Also, if a re-pair was needed, the pairing code is mutch shorter.

So I have to use that pump now, instead of my lovely DanaRS. :(

[wootmasterslick]

Seems like I just had this problem with dana-i. Does this screen look familiar?

[Alamo04]

No, it isn't a pairing window.

Your screen shows only that your pump wasn't connected in AAPS. Perhaps empty battery?
