WE826 + MC7455 Issues
Posted: Thu Dec 26, 2019 7:12 pm
Hello All,
I have built 3-4 of these setups with an mc7455 and a we826. However, this particular one is giving me a headache. Ive tried so many different things including everything on the troubleshooting page. So im curious if anyone can help point me in the right direction. The Debug Information constantly repeats the same thing over and over(after it runs through the initial info of modem info, sim info etc) the message it gives me is:
From the information ive read this has something to do with SMS an im not sure if its the actual cause of my issue or not. When running at!gstatus? I get a few statuses that are concerning, one is the PS State: Not Attached, EMM State: Deregistered. Also there is no values in the PCC RxM nor PCC RxD. This leads me to believe that its not getting a signal. Ive used it in this location in the past without any issues. So then I thought maybe it was the u,fl connections to the modem to antenna. I have checked them numerous times. One of the connections does feel looser than normally with a u.fl connector but they both still make a decent connection. Ive also tried using different antennas with a different u.fl cable going to the modem with no luck.
Can anyone point me in the right direction of how i can narrow down the issue? Below is some of the information I have gathered trying to get it to work. Any help is greatly appreciated!
