Xdrip + G6 + OmniPod5: bluetooth settings

[phjund]

technical details: Xdrip version (fe9ec2e-2024.11.03) + OnePlus 12R A15 + Omnipod 5 3.1.2-p001 + Dexcom G6
Hi,
I'm a user of AAPS but was proposed to test the Omnipod5 algorithm for 3 months.
My sensor is the Dexcom G6 which I still start using Xdrip+ because I like it and it seemed to work (in the beginning).
The problem I encounter now is that for long periods of time during day and night the Omnipod5 PDM (the "collector") doesn't receive the BGs from the sensor even though I see no signal interruption on Xdrip.
I started looking for answers and I found that a Bluetooth conflict created by Xdrip could be at the origin of this problem. I removed most of the "aggressive" Bluetooth options in Xdrip and I enabled the "engineering mode" because I read that I could fix the BT channel that way.
I started this yesterday morning by fixing the BT channel in Xdrip to 1. The whole day I didn't get any signal interruption on the PDM. But last night at 1am exactly the PDM ceased to receive the BGs. I had alarms the whole night :-( and this morning I disabled Xdrip and then the signal on the PDM came back. Nevertheless when I turned Xdrip back on I didn't get anymore the BGs on Xdrip. But when I changed the BT channel to 2 everything came back to normal and is still running OK as I'm writing.
I have several questions: is it Xdrip that changed it's BT channel from 1 to 2 at 1am or is it the PDM ? If it's Xdrip, is there a way to avoid this change ? Do you have specific recommendations for the BT parameters of Xdrip in order for it to come second (after the PDM) when the sensor broadcasts the BGs ? For the Omnipod5 loop to work, it is important the PDM gets continuously the BGs and has priority over Xdrip and this is what I would like to achieve but I need some help from experts on Xdrip for that...
Thanks in advance for any help.

Anything that is behind engineering mode is there for developers only.
If it was meant to be used by the users, it wouldn't be locked behind engineering mode.

You say that the pod disconnects. Do you by any chance also have a Dexcom G6 receiver? That could interfere with your pump.

[Navid200]

No, I would use the official Dexcom app.

I have no idea what's going on. One possibility is that something is wrong with your G6 transmitter. If that is the case and you contact Dexcom or Omnipod for support, they will expect you to be using the official Dexcom app.

If you switch xDrip with Dexcom app and Dexcom app and Omnipod both coexist with no problem, we will know the problem is xDrip. But, you mentioned that when using xDrip, it doesn't stop working right away. So, you should give it a chance and use it for a while.

In the meantime, you will not be able to use AAPS. I am sorry. I have no other ideas I am sorry.

The fact is that you are the only one who has reported this. A question comes up why everyone else who is doing something similar is not having any problems. So, I am hoping that we can identify something specific about your setup that is the case of the problem.

Unfortunately, I cannot think of a fix we can apply that would immediately solve your problem.

Actually, if you can use BYODA with AAPS, that's not a bad idea for the troubleshooting. Go for it.

I will do the test with Dexcom and report back here. I know that without Xdrip life won't be that "fun" !
I attach two pictures I sent this morning to my healthcare supplier that illustrate my problem (I should have done this in my first message).

[phjund]

Yes that was the idea with BYODA: continue to use AAPS.

Hi,
So I did two days of testing with BYODA and then switched back to two days with Xdrip.
I had also interruptions with BYODA but less frequent and shorter ones. When I switched back to Xdrip at first everything was fine but then again during the second day long interruptions followed by automatic reconnections (no human intervention necessary).
Concerning what is illustrated in the last figure I believe this is due to the "engineering mode", so that's on me !
To sum up I think BYODA broadcasting to Xdrip and AAPS provides a more stable G6-O5 connection than using directly Xdrip to control the G6.
That's my personal experience and can be linked to my settings on the phone or on Xdrip.
Thanks to @Navid200 for showing me the ways to easily switch between Xdrip and BYODA !
