ESP32 Forum

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.
