I tried to connect the Small BMS NG via the new Bluetooth integration on a Cerbo GX with firmware V3.80.

When I do I get a lot of random continuous alarms. If I connect to the BMS with Victron Connect from my iPhone the BMS is working fine and there are no errors.

I have tried this on two separate Cerbo GX units.

Has anyone else been successful with this connection.

Could you please make some screenshots of the errors?

Hi,

So, I have solved my issue. Looks like I had a single digit in the Encryption key typed in incorrectly. As I was copying and pasting this each time I was repeating the error in each Cerbo.

Once I set up an additional BMS and Cerbo to tests with I realized my mistake.

At least now I know what to look for if I enter an incorrect key again. :blush:
