I am trying to work on a project for which I need to connect the Pixhawk Cube’s Here2 or 3 GPS module in order to access some parameters. But I am unsure of how to do so and couldn’t find a resource of it as well.
Please help! Thanks in advance.
What parameters do you want to change? There is a change that PX4 will (or can) change them on your behalf.
That being said, have you checked these instructions?
I actually want to access the log files maintained by the GPS receiver
uBlox stores logfiles? Have you checked the link I provided above?
