Error when using raspberry pi 4

[dawson-friesenhahn]

I've been using your repo on a very old raspberry pi model B v 2.0 running Linux raspberry pi 6.1.21+ with great success. I had to use a USB dongle for Bluetooth, but it worked without a hitch.

I recently upgraded to a raspberry pi model 4B running Linux raspberrypi 6.1.0-rpi6-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.58-1+rpt2, and I cant for the life of me get connected. The error message comes from gatt I believe, and isn't very helpful:

(.venv) pi@raspberrypi:~/renogy-bt $ python example.py INFO:root:Init RoverClient: BT-TH-774B0D88 => f4:60:77:4b:0d:88 INFO:root:Adapter status - Powered: True INFO:root:Starting discovery... INFO:root:Devices found: 16 INFO:root:Found matching device BT-TH-774B0D88 => [f4:60:77:4b:0d:88] ERROR:root:Connection failed: le-connection-abort-by-local

I've tried using both the pi 4's native Bluetooth hardware and the old functioning Bluetooth dongle with similar results. bluetooth, bluez, and gatt are all the most recent versions.

Also tried:

1. Upgraded power supply to 20 watts
2. Pasted identical Bluetooth config files from functioning raspberry pi
3. Apt updated everything
4. Reflashed
5. Rebooted the Bluetooth controller of the renergy Rover charge controller

Any advice in terms of avenues I should pursue for further debugging?

I haven't really tested it on Pi4 hardware. What does your etc/bluetooth/main.conf say? Have you tried using an older version of bluez (like 5.5)?

[emresaglam]

I created a docker container for renogy-bt for linux/arm/v8 and I'm using it with my Rpi4. If interested I can throw a quick write up. It might help you @dawson-friesenhahn

[dawson-friesenhahn]

That would be fantastic. I've put this project on the back burner for now, but that write-up could prove very useful once I'm able to pick it up again. Thanks!

On a Pi5, experiencing the same error. ERROR:root:Connection failed: le-connection-abort-by-local - The only thing I would add is that occasionally it does connect; if you retry the script 30-40 times or such... Once connected it is quite stable however.

[matthewcobb]

I'm not sure if this is useful, but running btmon whilst trying to connect brings up some logs. I have manged to capture both the failed and occasional successful connection. Is there potentially some sort of timeout issue, and only occasionally it manages to connect in the allotted time? Forgive me, this bluetooth debugging is new territory!

Just an update, I rewrote the bluetooth management side of this for my own purposes to connect using Bleak. https://github.com/hbldh/bleak and it is now working great on Raspberry Pi 5. It also seems to provide a much simpler way of managing device connections and callbacks.

@matthewcobb Feel free to raise a PR against the bleak branch.

Experimental bleak branch is now available
