Can't read GPS Data

[Gringoire]

Hello everyone,
i have an OBD II data logger, but i write here since it looks like that forum has been abandoned, and no one is answering.

I try to read GPS data over BLE, but they are always all 0. Any idea on why does it happens, and how to fix it?

Thanks for the help

How did you read data via BLE? What firmware configuration do you use?
