Hello @FrancineMatos thanks for the PR. Did you find it any more stable than the original version in your testing?

Hello @FrancineMatos thanks for the PR. Did you find it any more stable than the original version in your testing?

To be honest i never faced some connection problems after its connect only when tring to connect, my Raspberry Pi 4 is about 1 meter from the BT-1 Bluetooth probability its helps a lot.

I mean at start, when i restart the Py it's take a while to connect, i solved that creating a service to start the script example.py, so when the connection fails the script just restart and keep trying to connect.

But one time it's connected it's keep alive for a long time. Maybe it's disconnect some time but like i told the service do the trink and just restart the script, so i not even notice the disconnection and i have some automations that relay on pv power readings and everything goes well.

One thing that i can say is that every time that i faced a disconnection it's faster restart the bluetooth service from the Py to reconnect faster, it's looks like that even the python can't connect properly the bluetooth connection with the BT-1 keeps anchored, so when you restart the bluetooth the BT-1 appears to properly disconnect and accept new connections more easily, considering it only accepts one connection at a time.

I have a battery monitor for my BMS on the same system and it also uses bluethoot for this, sometimes I face the same problem with it, so when I identify that one of the two readings has dropped, I just restart raspbery py's bluethoot and the the trick with the service takes care of the reconnection.
