Jk Jk-b2a24s20p disconnection issues..
Catchmydrift opened this issue · 5 comments
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.
this shouldve been fixed in the meanwhile
