Hi,
I’m using the LTE-M cellular kit with my RPI Zero: Raspberry Pi Cellular IoT Kit (LTE-M) - Sixfab
I’m using the included Sixfab SIM as well. I followed the setup guides for Sixfab Core.
I have verified signal using AT+CSQ, and registration to a regional carrier using AT+COPS?
When I try ifconfig wwan0
, I get this as the output:
wwan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet <removed for privacy> netmask 255.255.0.0 broadcast 169.254.255.255
inet6 <removed for privacy> prefixlen 64 scopeid 0x20<link>
ether <removed for privacy> txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Sometimes, the RX and TX will show errors, like this:
wwan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet <removed for privacy> netmask 255.255.0.0 broadcast 169.254.255.255
inet6 <removed for privacy> prefixlen 64 scopeid 0x20<link>
ether <removed for privacy> txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 120 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 43 dropped 0 overruns 0 carrier 0 collisions 0
I have not been able to get my device online through LTE, and hoping these might provide some clues. On the Connect dashboard it always just says “Cellular Connection Unavailable”.
Not really sure where to go on this… Would appreciate some help for some next steps to figuring this out. Thanks!
Edit: I forgot to mention that I have also updated the firmware of the modem to the latest version following Sixfab’s guide.
