i'm trying to get RB433UAH with ROS 4.3 working with two USB 3G modem (Huawei E220).
Both modem work regularly alone, but I I try to use both of them i'm able to see on a port (usb2) so I cannot start second ppp-client connection.
Any idea abot how to get them working?
I need two modem to sum prepaid traffic of two sims (20G+20G or 300h+300h).
I'm trying to write a script to bring down connection with exhausted traffic ad bring second one up (any suggestion is appreciated).
