Note: I looked in the “gatt_explorer1.txt” output file and it was blank, so I attached the terminal output.

To speed up the integration please see if you are able to capture the Bluetooth traffic while using the vendor app with the battery.
Note: I do not have an Android phone and dig some digging to try to perform the same on iOS and came across https://novelbits.io/debugging-sniffing-secure-ble-ios/ which appears to have the equivalent instructions on how to capture Bluetooth traffic on an iOS device using MacOS hardware. I have attached the file to this request as an exported “BTSnoop” format, which I can confirm can be opened in Wireshark.

Again,
Thank you so much for your work!

Hi @JohnsonDanielsHA! Perfect input, you provided everything I needed. It's even simpler than anticipated, they use a JBD BMS which is already supported. My tests using your captured traffic passed, so you can try the version on the linked branch (see right column of this issue). If you need install instructions, have a look at how to install manually. Let me know if it also works for you!

Hi @patman15

I appreciate the quick turn around and work!

I have added the linked branch and can confirm everything is working!

Thank you again!
