TCP AT+CIPSEND +CIPERROR: 4 #121

Open ALEEF02 opened 3 years ago

ALEEF02 commented 3 years ago

Hey guys,

I've got an incoming TCP stream to work on the SIM7600E and I'm trying to reply to it. Using AT+CIPSEND I get the error

-> +CIPERROR: 4
-> 
-> ERROR
-> 
-> ERROR

Using the manual here, page 270 informs me that the error is "Operation not supported". Am I doing something wrong, or can we truly not send an outbound TCP stream with the SIM7600E?

Thanks!
