Response definition of %XMONITOR

[Siyou]

Hi 

We are using %XMONITOR to get the network status and parameters, but we cannot understand some of its response:

1), sometimes, the PLMN may be "FFFFFF" and TAC may be "FFFE" even the reg_status is 1(Registered), what's meaning of them? when they are "FFFFFF" and "FFFE", the network data transfer will be not available

[2020-04-27 14:56:23.934 R]%XMONITOR: 1,"xxxx Network","xxxx","FFFFFF","FFFE",7,0,"FFFFFFFF",,,,,"0010","00011110","10000011"
OK

2), Even the device is attached to network(reg_status is 1), sometimes the response has not the rsrp and snr values, why the modem has not these signal quality values when it is in network?

Hello, 

What do you get if you use the +CEREG command? Can you provide full output from the AT Client Sample?

Kind regards,

+CEREG: 1,"FFFE","FFFFFFFF",7,,,"00011110","10000011"

Thank you! Can you please provide AT client sample output? If that also shows the same, then we would also need a modem trace. Can you please try to follow this guide on that topic? And attach the .bin file.

Thank you!

Kind regards,
Øyvind
