Startup and WiFi connection are more fast in ESP8266 than ESP32-C3

[agi63_ita]

Hi all,
I'm working with ESP32-C3 with uart AT-commands mode. I use it to connect at WiFi AP as a client.
If I have WiFi network configured, and AUTOCONN enabled, when power-up modem sequence is:

boot --> "ready"

and than URC:

WIFI CONNECT
WIFI GOT IP

Problem is the delay from "ready" to WIFI CONNECT:

in the ESP8266 about 1s
in the ESP32-C3 about 3s

What could be the problem?
I noticed that (in the ESP8266) going from version 2.1.0.0 to 2.2.1.0 the same thing happens!
My device is battery powered and and more time WiFi ON means more consumption!

A big thank you to anyone who can help me, otherwise I will continue to use ESP8266.

bye
Andrea

Hello, have you tried the v3.3.0.0 firmware: https://docs.espressif.com/projects/esp ... aries.html

in my test, it seems work well every time, see the attachment.

Could you please check your firmware version.

thanks for your reply, I use the same version of modem firmware as you.
In my WiFi connection I use DHPC mode, is it the same in your test ?
Thanks
Andrea

yes, dhcp is enabled by default. Otherwise, it will obtain an IP address (actually, use the static ip address) more quickly.
