Hello,
I'm trying to connect to my JiKong BMS PB1A16S10P via bluetooth from raspberry pi, but it doesn't seem to work.
I'm able to connect from the mobile app and read all the data there, but I would also like to have access to my BMS when I'm away.

Here is my output

`(jkbms-monitoring) pi@raspberrypi3:~ $ jkbms -p C8:XX:XX:XX:XX:XX -P JK02 -c getInfo
2024-12-14 20:28:51,632:WARNING:jkbleio:ble_connect@67: Cannot connect to mac C8:XX:XX:XX:XX:XX - exceeded 3 attempts
2024-12-14 20:28:51,632:ERROR:jkbleio:send_and_receive@46: Failed to connect to C8:XX:XX:XX:XX:XX
Command: getInfo - BLE Device Information inquiry

Parameter Value Unit
validity_check Error: Response was empty

`

Any idea what might be wrong?

could be that the bluetooth stack has errored (often happens with the library Im using)
try a sudo systemctl restart bluetooth
also add debug flag to command -D and post the output

still not connecting the device's mac.. is anything else connected at the same time?
try sudo hcitool lescan
or use bluetoothctl to see what the system is reporting for devices

I can see my BMS in the list of available devices. Both hcitool lescan and bluetoothctl scan can see it

can you try installing powermon and running
powermon-cli --bleScan --details --advData --getChars --address <mac address>
this uses a different BLE library (more modern) compared to mpp-solar and does a detailed query - so will show what the newer python lib can see

getting this error when trying to run powermon-cli
