Got a problem with the RB912UAG-2HPnD boards, Sierra Wireless MC8780 cards and ROS 6.x.
Under ROS 6.10, every now and again, I can bring up a ppp-client interface on the MC8780, but most of the time all I get is:
The port itself is showing as invalid:
ppp-out1: resetting link... - could not acquire serial port
and there doesn't seem to be any way of resolving this - doing a
[admin@MikroTik] > /port print Flags: I - inactive # DEVICE NAME CHANNELS USED-BY BAUD-RATE 0 I 1:2 usb1 3 9600
sometimes cures it, but other times the port just shows as invalid after a reboot.
I have twelve RB912s and 12 MC8780 cards and they are all giving this error. The boards all work perfectly with Huawei EM770W cards.
Everything works perfectly under ROS 5.26 (but of course, I don't have access to the functionality I require)
If somebody can help get these working under 6.10, I would be very grateful.
