Device status is online but Cellular connection is not working

[perw]

Hi

Have just bought a Sixfab HAT for my Raspberry Pi 4 with Telit LE910C4-EU module. I’ve followed all installation instructions but I’m unable to get a connection. I assume the connection should work even if WiFi is active. My Dashboard at Sixfab says that ICCID is unknown although I’m sure I entered that correctly during installation.

Please advise.

Hi,

Could you please share the output of the commands AT+CPIN? and AT+ICCID?

@perw

I assume the connection should work even if WiFi is active

If your device has Wi-Fi, it should appear online. Did you encounter any errors during the installation? Could you please restart the CORE services using the following commands:

sudo systemctl restart core_agent.service 
sudo systemctl restart core_manager.service

Hi
Some additional info. WiFi works ok, I guess that is why SIM details is available at connect.sixfab.com.
AT commands doesn’t seem to work as expected. I’m getting a Timeout if the blue led is off and ERROR when it’s on.

perw@raspberrypi:~ $ atcom --port /dev/ttyUSB2 AT+CPIN?
[ERR]   Timeout, couldn't get response
perw@raspberrypi:~ $ atcom --port /dev/ttyUSB2 AT+CPIN?
AT+CPIN?
ERROR

perw@raspberrypi:~ $ atcom --port /dev/ttyUSB2 AT+CPIN?
AT+CPIN?
ERROR

perw@raspberrypi:~ $ atcom --port /dev/ttyUSB2 AT+ICCID?

ERROR

I did the installation some weeks ago, but can’t recall that I got any errors.

Restarting the services seemed to work ok but still no connection. sudo status core_agent.services or core_manager.services didn’t turn up any new messages.

Checking dmesg -T gives this set of messages repeated approx every minute.

If you activate the remote support setting of your device and share the support key with me, I can help you quickly. Could you PM me your remote-support token so that I can check and solve it? Thanks.

[perw]

Hi Ensar

I just discovered that the SIM card was not fully inserted.
I’ve restarted the core services.
The blue led is now blinking approx once every second.

perw@raspberrypi:/var/log $ atcom --port /dev/ttyUSB2 AT+CPIN?

+CREG: 0,5

OK

perw@raspberrypi:/var/log $ atcom --port /dev/ttyUSB2 AT+ICCID?

+CREG: 0,5

OK

Anyway, I’ve posted the remote support token

Regards,
Per

[perw]

Actually, seems like my problems might have disappeared…?
At least I’ve a normal IP-address on wwan0 and connect.sixfab.com reports Cellular Connection Available.
I’ll do some more testing tomorrow.

Cheers,

Hi

Seems I’ve been mixed up in using correct install procedure. I’ve partly followed “Setting up a data connection over QMI interface using libqmi” and partly “Setting up the PPP connection for Sixfab Shield/HAT”. I’ve also followed Twilio Setting up the PPP connection for Sixfab Shield/HAT procedure and the result is probably that I may have to do a complete reinstall.

Sorry about that.

Regards,
Per
