Briefly summarize the issue being raised So I went through all the steps to connect the STM32L4 to the AWS Cloud although I have encountered an error with the MQTT (the error I am receiving on Tera Term is shown in the references below), how do I rectify this issue?

Can you share the policy attached to your certificate?

What version of amazon-freertos are you using?

From the logs it seems that it is failing due to the incoming packet having type 1, which is a CONNECT packet; this should not be received from the server.

@Obinex Any answers to the questions above?

AniruddhaKanhere commented 1 year ago

I agree with @archigup (with a minor correction) - I don't think that packet of type '1' is valid at all. CONNECT packet is 0x10 when printed in the logs since the 1 is shifted 4 times into the higher nibble of the byte.

Can you capture some logs using Wireshark? It will help us figure out the bug much faster.
