I’m testing to send SMS over Windows hyperterminal, but facing difficulties with error code 500
This is the command that I try to sent over the terminal:
AT+CMGF=1
OK
AT+CSMS=0
+CSMS: 1,1,1
OK
AT+CNMI=2,1,3,1,1
OK
AT+CSMP=49,169,0,0
OK
AT+CMEE=1
OK
AT+CMGS=“+62817150033”
test
+CMS ERROR: 500
Lookup for error code 500: unknown error, the testing for receiving sms over terminal is success.
Any kind of help would be appreciated.
Regards
