Trouble with AT-command terminal.

[Eric592]

I’m new to this custom router stuff! I built a router using a raspberry pi 3 b and a SIERRA WIRELESS module MC7455 LTE 4G module I’m connected to the internet and was able to use my at commands before but now when I try to type a command it just disappears while typing it. is there something I’m doing wrong?

I've seen this with the latest version of GoldenOrb. Is that what you're running?

I recall too that some users have to put there modem in QMI or MBIM mode for this to work as well. I have a MC7455 that I run in MBIM mode just fine, but on a older version of GoldenOrb (from last year).

I figured it out finally i got it up and going now. I found a few post on how to reset the modem and stuff back to oem and just redid the at commands works fine now!
