Hello,  
Im using BW16 RTL8720DN Wifi Module and firmware version is

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](https://aithinker-combo-guide.readthedocs.io/en/latest/docs/command-set/MQTT_AT_Commands.html)

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.

Hello @mssiva1 ,

Thank you providing the sdk information and log.

Unfortunately, we are not maintaining for [MQTT AT 命令集 — 安信可科技 documentation](https://aithinker-combo-guide.readthedocs.io/en/latest/docs/command-set/MQTT_AT_Commands.html) from AI-Thinker. Ameba IoT only supports Arduino SDK and Standard SDK Realtek’s AT command on [GitHub](https://github.com/ambiot). Therefore, you should raise this question to AI-Thinker’s channel instead of here.
