What makes you think that the module has built-in support for MQTT? :thinking:

download (1)
I used this development board for MQTT and tested, so now we used module only with atmega2560

5

So why can't you just do the same as whatever you did with that dev board? :thinking:

Please give a link to that dev board.

Does that module have the same firmware as whatever was in the module on your unknown dev board?

What's that?

It's nothing like what you posted in post #4!

Sorry i have moved to another project, so some delay in testing this.
I have updated the firmware to the following

at version:release/V4.18_P2.29.2
sdk version:amebad_v6.2C
firmware version:release/V4.18_P5.6.4

I have connected with my MQTT server and able to publish message to server. but i cant able to read / receive the subscribed (new) message. How to get the message.

At commands - MQTT AT 命令集 — 安信可科技 documentation

Above is the AT Command list im using.

whenever i publish from the server i got the publish packet msg in UART_LOG

[AI_MqttKeepalive()-1341]send mqtt req
[AI_MqttDataHandle()-1555]Read packet type is PINGRESP
[AI_MqttDataHandle()-1555]Read packet type is PUBLISH
[AI_MqttKeepalive()-1341]send mqtt req
[AI_MqttDataHandle()-1555]Read packet type is PINGRESP

But no response in the UART. So i cant able to read the message.
