Hi everyone
I use EC200U module and i have problem with non-english USSD services.
response is in ucs2 format but return null.
i pretty sure service works. (tested with another gsm module)
the command i use:
AT+CUSD=1,"*780*2*1#",15
+CUSD: 1, "" ,72
>
even with these settings:
AT+CSCS: "HEX"/"IRA"/etc
AT+cgmf=0
and:
AT+CUSD=1,"*780*2*1# in hex format", 15 // return Error
what should i do?
is Firmware Update available for this issue?
