Medtronic 722 Version 2.2A Orange Pro fails to connect.

[haiweiaaa]

After updating to the new version 3.4.0.0 on a XIAOMI 14 phone, the Orange Pro Link app is unable to connect to the Medtronic 722 Version 2.2A insulin pump. After the first successful connection, the basal rate can be read, and the pump's time and settings can be retrieved. However, during subsequent connection attempts, the pump status shows a connection failure. It is impossible to connect to the pump to deliver bolus insulin or adjust the basal rate. Version 3.3.2.1 functions properly without these issues.

Did you run both AAPS versions on the same phone, or did you switch phones together with AAPS versions... Medtronic code hasn't change in quite a while now. Did you update Orange Pro Link too?

Are there any error logs with this problem? Try to recreate this and send the logs, maybe we can see something there that is relevant to this... In log settings enable all pump options (I think there are 3)...

Thank you for your response. I tested two versions of AAPS on two separate phones. Both can connect on version 3.3.2.1. For version 3.4.0.0, it shows a successful connection on the first attempt, but the pump status then displays "unreachable" and cannot connect again afterward.

Ok. We need to find out what is going on... Can you please supply the logs?

Hello, the log file from the phone has been sent to your email.

You need to reproduce the error and give me timestamp when error happens... Its hard to look through 30 log files, while error might not be even shown...

Hello, I have reproduced the error and sent a new email with the log.

I got logs from @haiweiaaa (will attach here)... From what I can see, soon after start we are starting to get back invalid pump responses. As I remember there was some change, when someone removed 500 ms delays from RileyLink communication... That could be the problem, why responses that come back are unrecognized. I currently don't have time to look into this. I would recommend that RL change gets reverted or at least configurable. But maybe I am wrong and this has some other reason...

I have reconfigured the RileyLink file and changed the setting to 100 ms，The connection and communication are now working properly，Thank you!
