Undocumented AT Response #17

Open rcsandell opened 4 years ago

rcsandell commented 4 years ago

Hello @Neutree ,

When using the AT command firmware, after approximately 8 hours of TCP/IP connection, the unsolicited AT response "+CGDMODIND:1" is issued.

The unsolicited "+CGDMODIND:1" response is not documented. What does the response mean?

After the unsolicited response, when trying to send data using "AT+CIPSEND=10", the module issues "COMMAND NO RESPONSE!" after 20 seconds.

Also "COMMAND NO RESPONSE!" is not documented.

What is the correct method to handle such responses?
