ESP32 wont connect to WiFi

[sommerper]

Basic Infos

Hardware

WiFimanager Branch/Release: v2.0.10-beta #9182622

Esp32:

Hardware: ESP Wroom 32

Description

After connecting to the AP created by the ESP32 I select my network and enter the password. WiFiManager tries to connect 4 times and fails.

[tablatronix]

how is that the same issue?

[tablatronix]

@sommerper change this to true and see if it connects, also enable esp debugging this sounds like a known esp issue

[MythicalForce]

how is that the same issue?

it was the wrong issue xD

[sommerper]

@tablatronix I've been pulling my hair out for several days now. Tried 4 different routers and set up an openwrt network on my pi to see if it was the network somehow.

Turns out something is interfering with the esp32 wifi when connected to an external power source.

If I'm powering the esp32 with USB only there is no problem. If I'm powering the esp32 with USB and a 5V laboratory power source it doesn't work.

I can't pinpoint what it is but at this point I'm pretty sure it has nothing to do with this library and I'm sorry for taking your time. If I find the reason for this error I will update the thread but I think we can close the issue.

Thanks! (for an awesome library)

Interesting, I know analog read breaks wifi makes me wonder if it has something to do with wifi calibration and vref

HELP MEE PLEASE?????

What versions you using ? 'class WiFiClass' has no member named 'softAP'

Wifimanager can not connect to Wlan same here. Using ESP32 Wroom 30 pin both of them will not connect with Wlan saved credetial as the monitor text below shows

The same sketch did work with ESP8266 and an othe ESP32 wroom 38pin type I have tried al i could think of and on a friends PC with his IDE old IDE 1.8x or new 2.04 no clue yet awaiting an other mini ESP32 and hope it connects

serial monitor shows:

connectTimeout not set that is the complain... could that be our common issue? I did not have to set anything extra at WifiManager
but only manager autoconnect("ESP32_AP , "password" )

question how to set this "connectTimeout ? is it Wifimanager.set connecttimeout=5 ore anything like that? where are those hidden pameters documented?
