TRB142 +CMS ERROR: 304 with PDU and 305 with text

I’m having trouble with m TRB142, it used to work fine until about 3 weeks ago. Short version is it appears to no longer be able to send multi part SMS or use PDU mode at all.

Current firmware TRB1_R_00.07.12.3

Previous firmware (same problem, tried updating) TRB1_R_00.07.09 i think

In full serial modem control:

PDU mode fails with +CMS ERROR: 304

Text mode fails with +CMS ERROR: 305 when trying to send multipart sms (short single part sms are sent ok)

I have tried from an application an directly from a terminal.

The failure is typically followed by a minute or so where the modem becomes unresponsive.

From the webgui (with serial control off), I can also send short messages, but when attempting 2 part length or more it takes a long time, appears to have sent, but the message does not get delivered (or sometimes shows up after an hour or 2)

Is there a known bug or some reason this has started, or has the device malfunctioned?

Hello,

Apologies for a delayed response. Could you confirm if the initially described issue is still replicable with the latest 7.13.3 firmware installed on your TRB142?

Additionally, if possible, could you test with a different SIM card to check if the same behavior occurs?

If the issue persists, we will need to contact you privately to investigate and troubleshoot it more effectively. Please let me know if the problem still exists so I can send you a form to reach out for further assistance.

Best regards,
