Hi everyone,
I need to read a GPS from a RobOvero through its UART. However, in Python client examples there is not information about changing baud rate and other UART parameters. I've seen that it may be done from C, but isn't there any way to do it from Python directly?
Thanks and regards,

I've removed the networkmanager, but the network interface takes longer a long period to get working, after that I have to ifup wlan1 manually (do not know why it is renaming from wlan0 yet) to get an ip.
