I am looking to decode serial frames to get gps data
I am correctly connected but I can not find documentation on the protocol used to identify the data received

Hi @julien ,
If you have a uBlox M8 GPS, you can check in this datasheet.
But why are you doing that? The driver id already implemented in px4 and you can see the important GPS data with the command gps status

hi @bresch,
Thank you for your answer ,
I want to be able to retrieve the gps data for use in a program on stm32, but i dont know how are encapsulated the data in the pixhawks
