As the title says. I can receive, but I cannot send messages. It always gives me this -32602 error code.
Everything is up to date and the firmware version is 4.8.3 beta. Modem version: EM060KGLAAR01A12M2GA.
Hi, it seems to be related to the encoding format of the text message or the characters. Does your text message contain any special characters?
Could you PM me the complete text of the message to verify the issue?
No matter what the message contains it will won't send it. The message was "Test".
Meanwhile I did some research and it looks like the modem use a different mode. The modem can support PDU and TEXT mode. But no matter if I force TEXT mode (AT+CMGF=1) it will stay in PDU mode (AT+CMGF=0). As I understand the GUI tries to send messages in TEXT mode and it doesn't convert it before. This is what might cause the conflict.
The SMS encoding mode is PDU by default and cannot be changed. Router cannot send SMS seems to to due to IMS status. Now it should work. Could you try it again?
Now I can confirm that SMS sending is working.
