hello,
How can we read data from the pipe /run/mpa/vvpx4_sys_status/request in python in order to read the battery data (voltage,charge,current)

We do not provide a python integration. Reading from named PIPEs is really straight-forward but you would have to implement the request portion, etc as well.

See stackoverflow here: https://stackoverflow.com/questions/39089776/python-read-named-pipe

You can find the format how to read from autopilot_sys_status here:

https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-battery.c

It may be more straight forward to modify voxl-inspect-battery in C to publish the data in a format your Python code can easily ingest
