Didn't work with ESP32 C3 version

[Skywalkerf34]

Hi,

I just try advanced and OTA version form your sample. I did compile and run Serial give me AP and SSID ESP-xxxxx and a password But this device is not really on air ????

I just got a C3 to try it on myself.

Worked good on my esp32 C3. Using devkitc-02
I haven't tried the advanced or OTA eg yet.

I purposely put in the wrong pass for the chosen SSID for that test.

@Sys64736

Compliation was working fine for me too, the thing is I didn't find the device I setUp on air with sniffer.....did you have this "on air" ? then I will check again. As I am using original example, something maybe wrong in my environment /setup then

[Sys64736]

No, it's not. I thought it was connected, as it states in the serial but I was actually seeing my other C3 listed in the router. Debug states an IP of 255.255.255.255 so somethings off. I'm going to look at it a little closer tomorrow and see if I can figure it out.

[Sys64736]

@Skywalkerf34 It's working for me now and getting a valid IP.

Comment out the line below in WiFiSettings.cpp Line:469 WiFi.config(INADDR_NONE, INADDR_NONE, INADDR_NONE); // arduino-esp32 #2537

That line disables the DHCP on the router from handing out an IP. I think it was an issue from a while ago in regards to hostnames and router leases with multiple ESP32's connected. Hoping it's fixed now with the latest IDF

[Skywalkerf34]

OK, so This was exactly what I get myself....everything seem running on debug (serial) but nothing "on air"

[Skywalkerf34]

@Sys64736 Thanks Marc, I will try your patch soon and let you know what results on my side

[Sys64736]

Ok Francis, sounds good.

[Skywalkerf34]

@Sys64736

I comment the line 469 as you suggest then I try both basic and OTA example with same result : compile good with no warning, serial give SSID but still cannot find this "on air"

[Sys64736]

I don't know why you can't see the access point. Did you try another phone or computer with a WiFi radio. It does show up "on air" but sometimes you have to wait for a network list to update from a scan... usually 20-30 seconds but depends on the device.

[Skywalkerf34]

@Sys64736 Yes I check on my computer and on my phone with Swiffer scanner....same ???? I will try later same code with a "real" ESP32 to compare thanks for your kind help

[Skywalkerf34]

@Sys64736 Happy new year ! I try with an ESP32WROOM with basic example and it works great! Witch mean that this is ESPC3 issue is it because single core ???
