I’m using the 4G/LTE Base Hat with the Telit LE910C1-NF. I had it all working, and it was able to talk to the internet over the wwan0 interface… Then yesterday for some reason it has stopped working. I still get an IP address on wwan0 and a route to the outside via the gateway, but it can no longer communicate:
$ ping -I wwan0 google.com PING google.com (188.8.131.52) from 192.168.225.37 wwan0: 56(84) bytes of data. From 192.168.225.1 (192.168.225.1) icmp_seq=1 Destination Net Unreachable From 192.168.225.1 (192.168.225.1) icmp_seq=2 Destination Net Unreachable
According to Sixfab Core, the device is online, but the cellular connection status says “Cellular Connection Unavailable”. It says my roaming operator is AT&T.
It seems there might also be an issue with ECM initialization, though it’s not clear:
$ tail logs/cm-log 2021-03-18 18:22:27,663 --> modem.py INFO APN is up-to-date. 2021-03-18 18:22:27,665 --> modem.py INFO Checking the mode of modem... 2021-03-18 18:22:30,305 --> modem.py INFO Checking the network is ready... 2021-03-18 18:22:30,997 --> modem.py INFO SIM is ready. 2021-03-18 18:22:31,657 --> modem.py INFO Network is registered. 2021-03-18 18:22:41,669 --> modem.py INFO Checking the ECM initialization... 2021-03-18 18:22:42,354 --> modem.py INFO ECM Connection is initiating... 2021-03-18 18:22:49,167 --> cm.py ERROR initiate_ecm() -> ECM initiation failed! 2021-03-18 18:22:49,369 --> modem.py INFO Checking the ECM initialization... 2021-03-18 18:22:50,060 --> modem.py INFO ECM is already initiated.
Also when doing those ping tests that are failing, it still shows up in the sixfab dashboard as data usage which is charging me, even though the communication is failing.
How best can I get this working again? Perhaps something got goofed up and there’s a way to “factory reset”?
