ESP32 MQTT ACK Time

Postby gustavor2t » Wed Jan 08, 2020 9:01 pm

Hey guys,

I currently use a ESP8266 with AWS Mqtt. In general, wifi connection plus mqtt ack takes about 20 seconds.

I was wondering how much speed up would I get if switched to a ESP32 since its TLS/SSL authentication is faster.
Does anyone have any experience with this and can share?

Thank you,

I'm running an ESP32-based sensor which
  • awakes from deep sleeping,
  • measures e.g. temperature,
  • connects to wift,
  • connect to local MQTT server,
  • publish the data to MQTT topic,
  • disconnects MQTT and wifi,
  • goes to deep sleep.
All this takes about 2 to 2.5 seconds. Most of the time is used by the wifi connect.

I hope this helps a bit.
