I have a custom application running on a RAK5010 and have a couple dozen devices out in the field that are functional. What I’m experiencing is that a device will no longer be able to connect to the cellular network.
I have a device that was running for over 3 days that just stopped connecting to cellular. I booted it into debug mode where have have a AT console and tried to manually connect.
AT+COPS=? returns a list of possible operators, but no matter which one I select I get ERROR 30.
I’ve tried with a couple different SIMs and have tried various Antennas (signal on all are really good).
So I don’t know where to look. Could this be an issue on the network side? I changed SIMs but is there an ID of the device that might be getting block regardless of SIM?
Is it possible that this RAK5010 has failed for some reason? (I have 4 devices over the last few months all have the same issue).
I’ve tried different power - USB, Battery, combination, etc. I’ve rebooted numerous times.
I need to find out where to look and a solution to this. I’m not sure if it is at the SIM provider side (Telnyx) or if its local operators (AT&T and T-Mobile) or if it’s Hardware (RAK5010 or BG96).
Thanks in advance.
