Hi, having connection issues with JK bmses 2 x Jk-b2a24s20p. They connect initially, but for only about 1 minute, then disconnect. They will reconnect a few minutes later, then the cycle repeats.. Any clues from the code below?

Thanks 👍

(it was all working fine untill i had to upgrade home assistant due to putting it onto ssd instead of sd card.. Wasnt ever going to upgrade, but was forced too..)

There is a bug which causes the batmon process to exit, specifically

await asyncio.wait(loops, return_when='FIRST_COMPLETED')

returns with global variable shutdown being False. I have no idea why this is happening on a disconnect

When BLE connecting is closed by disabling the bluetooth hardware, the process doesn't exit.
Seems to be related with bleak and/or asyncio. Very weird

I have two of the jk bmses, one will usually connect reasonably reliably, but the second one will never stay connected for very long unfortunately. The bmses are the same model.
