As the title says I am not able to send data to my MQTT. I am able to Open the MQTT and get the desired responses. I am able to get response “OK” after sending the payload. But it is now getting reflected in MQTT explorer.
I am using the following command for sending the payload.
“AT+QMTPUB=0,0,0,0,"test.mosquitto.org/device/av/amazon/1","{\"Hello MQTT Explorer\"}"”.
Is there anything wrong am I doing ?
If yes, what is the correct frame ?
If no, what must be the reason ?
Your responses are crucial, thanks in advance for your time and efforts.
hello, could you tell us your module type or firmware version? thanks~
Hello,
The I am using Quectel EC200U-CN. I am using STM32 controller to send AT commands. I have put check for the responses and I am able to get standard responses but not able to send data.
Hi @goks2303
Can you try to publish a message using the AT+QMTPUBEX command? The command format is as shown below.
No, I am not able to send message via using the AT+QMTPUBEX. I am not getting “>” as a response.
(“AT+QMTPUBEX=0,0,0,0,\device/av/message,1”) this command is giving me an ERROR as an response.
