I’m having trouble sending sms with WP7702 module.
By sending AT commands via “microcom -E /dev/ttyAT”, I encounter an error ( +CMS ERROR:350 ), but I can’t find any meaning for this error in the forums.
Here is the error : ( I can only upload one picture )
I checked also if the SMS were active :
I checked if the firmware version was up to date and it was:
Also, when I try to send a SMS with this sim from a phone, the next message appear :
“No network support for messages”
Have you any ideas about the meaning of this error and a solution ?
I work with a mangOH red
Thanks in advance !
