Password JKBMS Bluetooth

[testarz]

Thankfully i can connect my Raspberry Pi to my JKBMS over Bluetooth with the dbus-serialbattery. This unfortunately only works, when the password is set to 1234 in the JK Software. Is there a possibility to change the password?

Thanks for suggestions

Just read the notes after you install the driver...

dbus-serialbattery/etc/dbus-serialbattery/reinstall-local.sh

Lines 523 to 535 in ac892a1

	echo "BLUETOOTH battery connection: There are a few more steps to complete installation."
	echo
	echo " 1. Add your Bluetooth BMS to the config file \"/data/etc/dbus-serialbattery/config.ini\"."
	echo " Check the default config file \"/data/etc/dbus-serialbattery/config.default.ini\" for more informations."
	echo " If your Bluetooth BMS are nearby you can show the MAC address with \"bluetoothctl devices\"."
	echo
	echo " 2. Make sure to disable Bluetooth in \"Settings -> Bluetooth\" in the remote console/GUI to prevent reconnects every minute."
	echo
	echo " 3. Re-run \"/data/etc/dbus-serialbattery/reinstall-local.sh\", if the Bluetooth BMS were not added to the \"config.ini\" before."
	echo
	echo " ATTENTION!"
	echo " If you changed the default connection PIN of your BMS, then you have to pair the BMS first using OS tools like the \"bluetoothctl\"."
	echo " See https://wiki.debian.org/BluetoothUser#Using_bluetoothctl for more details."

Thank you for the suggestion, i tried it first with my changed code and it didn´t work. then i found exatly these notes and changed the code siply back to 1234. After that, the connection worked immideatly. but when i change it now to something else again, the pi won´t connect anymore an the driver starts again and again

Does someone know where/how the default pin is set in the install setup? Tried some simple grep'ing but didn't find a 1234 reference. I could not get my jkbms to connect via the debian directions linked in the install notes (https://wiki.debian.org/BluetoothUser#Pairing_using_CLI) but it works just fine if I edit the config for dbus-serialbattery and do the re-install after changing to the default '1234' pin. I know it's a bit of a dirty approach to the issue but could also be nice if there was a way to set the new PIN somewhere in code/config as the install script already sets up bluetooth cleanly.
