No responses to AT+ commands

[DazWilkin]

I'm able to send values to the TTLtoWiFi and see these reproduced on the serial device connection.

I don't receive responses to the AT commands documented in the manual.

What am I doing wrong?

telnet> open 192.168.4.1 9000
Trying 192.168.4.1...
Connected to 192.168.4.1.
Escape character is '^]'.
Test
AT+STAINFO
AT+STASTATUS
Test

And, on the serial connection:

Test
AT+STAINFO
AT+STASTATUS
Test

I expect responses to the AT+ commands but don't appear to be receiving anything.

I had the same issue. Switching to “no line ending“ solved the issue for me.

@m-sja thank you! I'll try it today

[SmartArduino]

please try to use the AT command at serial port, Note NET interface.

If you send [LF] and or [CR] after the AT-Command the Module passes it through from MCU to NET instead of responding to the Command back to MCU. I would call this a Bug as this is not documented.

Thank you both for your help.

I am able successfully to issue AT commands via the serial connection suggested by @SmartArduino and using @m-sja suggested "no line ending" (e.g. AT+STAINFO, AT+STASTATUS) and receive the expected responses.

I am unable to use screen and PuTTY for the serial comms but this works with the Arduino IDE Serial Monitor.

Hello! I connect the DT-06 through the 2 motor & 16 servo board. When I send the AT + STAINFO command through the Port Monitor, there is no response. The sketch is written in Arduino:

String inString; int inChar;

SoftwareSerial portOne (3, 2);

void setup () {     Serial.begin (9600);     while (! Serial) {       ;     }     portOne.begin (9600); }

void loop () {     portOne.listen ();     while (portOne.available ()> 0) {       inChar = portOne.read ();       inString + = (char) inChar;       if (inChar == '\ n') {         Serial.print (inString);       }       inString = "";     } } I send the command through the terminal: echo AT> /dev/tcp/192.168.4.1/9000 How to make DT-06 execute AT commands?
