Using Bluetooth to read direct values

Hello everyone!!

Does VE offer an API or a method to via Bluetooth read direct values outside of the app, for example, to store current data into MySQL or a CSV etc?

Victron has in the past said that they would not publish the Bluetooth API as it's a moving target, and would require direct support from developers.

IMO, the world has moved on a bit since then, and GATT servers are pretty well understood at this point. I haven't spent any time on it since I was able to get the data I needed over the serial interface, but since I now have a BMS with bluetooth (and no UART), I'm motivated to start poking at it.

Ahh, Yes, I have no problem with reading UART data, I just figured this would be encrypted, do you know of any good GIT projects that parse the serial data from VE devices and is most of the data that comes out from MTTP these days standard in terms of format and schema?


Thanks BTW!

Hook up to the serial port, I think you'll be pleasantly surprised. The default configuration of my MPPT 75/15 was to emit human-readable and easy to parse data on the serial port. But if you want the full protocol, start here:
