Hello,

I am using module MC7710 in our device for connection to LTE. When I use !SELRAT=0(automatic selection) LTE connection works well. But when I use !SELRAT=6 (LTE only) module cannot attach to network. EMM state is still “Deregistered” and “Attach needed”

!GSTATUS:  
Current Time: 2220 Temperature: 38  
Bootup Time: 1 Mode: ONLINE  
System mode: LTE PS state: Not attached  
LTE band: B20 LTE bw: 10 MHz  
LTE Rx chan: 6400 LTE Tx chan: 24400  
EMM state: Deregistered Attach Needed  
EMM connection:RRC Idle

RSSI (dBm): -68 Tx Power: 0  
RSRP (dBm): -93 TAC: 57ED (22509)  
RSRQ (dB): -8 Cell ID: 01CE8900 (30312704)  
SINR (dB): 24.6

Have you ever seen this problem?

Regards

Jan
