Understanding The MQTT Protocol Packet Structure

[@emddom]

I liked this video a lot (and the others, as well). However, around 4:00 there is an extra 0 to the right of the 1 (i.e. you have a 9-bit byte :) ), this would be dec 128

Hi Thank you for the feedback I will try to add a comment to the video to point it out Rgds Steve

Hi, do you know how i can make a benchmark to the MQTT broker? I want to simulate certain amount of connections and measure the times they take to connect, subscribe and publish, with and without SSL. Thanks.

Thanks for the response. I did read this link before watching the video. I understood that there are 2 bytes reserved for the client id length. I am currently trying to connect to a MQTT broker via SIM800L module. When i send a CONNECT packet, i don't recieve a proper CONNECTACK. If you want to help me, i can share further details. Thanks
