Hi, trying to run the code after compiling against latest pull of libgatt, no success. have the same issue on ubuntu and on debian buster :

I apologize I was not notified that you made this report

I dont have this particular BT adapter; I'll see if I can pick one up to test with

Getting a similar error with my 16s JBD 100A bms with Bluetooth module.

Also getting the above error on debian bullseye amd64. Is there a fix/workaround for this problem?

I just got a JBD bluetooth adapter so I'll finally be able to test using it.

I know for a fact it works with one of these:

MLT-BT05

Give me a few days to mess with it.

Also, I dont use blutooth at all on the JBDs in my powerwall - all of my packs use a Wifi adapter:

@sshoecraft thank you for looking into this! If you need someone to test stuff, let me know.

RoySalisbury commented 2 years ago

Any update on this? I get the same connection error using BT.

mav- commented 2 years ago

Couldn't get this to work, spend too much time on it already. However, for what its worth, this did work for me:

Install https://github.com/Jakeler/ble-serial with pip install ble-serial. Run ble-scan to identify BMS:

$ ble-scan
Started BLE scan

A4:C1:38:19:9A:A2 (RSSI=-54): 16S10AH-LIGHT
A4:C1:38:F0:86:0D (RSSI=-91): 16S20AH50A

then run:

$ ble-serial -d A4:C1:38:F0:86:0D

Should get the following output:

21:34:19.750 | INFO | linux_pty.py: Slave created on /tmp/ttyBLE -> /dev/pts/0
21:34:19.750 | INFO | ble_interface.py: Receiver set up
21:34:19.913 | INFO | ble_interface.py: Trying to connect with A4:C1:38:F0:86:0D: 16S20AH50A
21:34:22.252 | INFO | ble_interface.py: Device A4:C1:38:F0:86:0D connected
21:34:22.253 | INFO | ble_interface.py: Found write characteristic 0000ff02-0000-1000-8000-00805f9b34fb (H. 20)

21:34:22.622 | INFO | main.py: Running main loop!

Now you can use jbdtool to connect to the serial port mentioned:

ok now thats cool. I'll check out ble-serial!

I finally got a JBD BT adapter and will start testing it in the next couple of weeks.

DeltaLima commented 6 months ago

I can confirm, that the solution from @mav- with https://github.com/Jakeler/ble-serial works fine. builtin bt support with libgatt does not work for me , i get the same error as posted above (debian 12 amd64).

But with ble-serial i am fine :)
