I we are trying to use the fx30s/wp7702 and it seems the radio disconnects after a random period of time (1-8 hours) and never reconnects, I waited for over an hour:
Power: ON
Current Network Operator:
Current RAT: Module not registered on network, RAT not available
Status: Not registered but currently searching for a new operator (LE_MRC_REG_SEARCHING)
Signal: No signal strength (0)
PS: Packet Switched Registered, home network (LE_MRC_REG_HOME)
If I simply do “cm radio off” and “cm radio on” it reconnects immediately and things are fine again:
Power: ON
Current Network Operator: TELUS
Current RAT: LTE network (LE_MRC_RAT_LTE)
Status: Registered, home network (LE_MRC_REG_HOME)
Signal: Very strong signal strength (5)
PS: Packet Switched Registered, home network (LE_MRC_REG_HOME)
I loaded FX30_WP77xx_full_R14.1.1.002-generic-SWI9X06Y_02.36.06.00 and we are using a non sierra sim. I made sure to set the rat to just LTE disabling GSM but it didnt help. Not sure whats going on with the modem. Why cant it reconnect and why is it looking for a new operator?
I have been reading posts about SIM connector issues? Its a 3 piece sim and some others have reported they can disconnect randomly. This is a known issue?
The fact that the network operator is blank when it disconnect sort of makes me think this is happening.
It could always register however it would disconnect randomly and stay disconnected for more than an hour. I thought I had the sim set to external with cm sim but that obviously didnt work. I will try to reproduce overnight.
Hi, Well the problem hasnt been fixed. The radio still disconnects and never comes back unless I manually cycle it. Here is are the at commands when it is stuck in the off state. I can easily fix it manually by cycling the radio. Not sure why it cant reattach by itself:
AT!UIMS?
!UIMS: 0
OK
AT+CPIN?
+CPIN: READY
OK
at!IMPREF?

The next time the issue occurs, could you please try the following commands:
AT!ICCID?
shell:
cm sim info
logread
This will dump out the syslog, and some sim state information, hopefully we can determine if the SIM is being disconnected.
Another thing to try would be to reproduce the issue, then pop the SIM out and reinsert, issue the ICCID command and cm sim and see if you can connect.
Some progress, nb was still enabled, I thought it was disabled. After enabling only catm the fx30 no longer disconnects forever. It still disconnects ~6 times a day but reconnects after a few minutes of down time. I dont know why this happens and is still not ideal.
I attached a log of this but its not very detailed. The other question I have is my sku is 1103882 the release notes dont list this sku as being supported. Is it supported by the latest release?
