[edg2411]

Board

esp32 wroom

Device Description

it is a custom board but uses the esp32 wroom 32e

Hardware Configuration

nothing strange

Version

latest master (checkout manually)

IDE Name

platformio

Operating System

windows 10

Flash frequency

40mhz

PSRAM enabled

yes

Upload speed

115200

Description

the provisioning example provided in the arduino libraries dont find networks by scanning or not scanning at all i dont know. The esp-idf version of the example works just fine im using the android provisioning app.
I see other issues but no one seems to help me

Sketch

it is the example without modifications, im using softap but same problem happens with bt

Debug Message

cant see any message, just not finding it in the app

Hi @edg2411 , could you please send a link to an exact example?
Please try to change the debug level to verbose, compile & flash again and post the serial output.
Can you please tell me something about the WiFis you expect to be found?

Hi thank you for replying

https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFiProv/examples/WiFiProv/WiFiProv.ino
it is the example that offers arduino ide
i did some debug and it is scanning the networks that are available just wifis from routers and common APs like my home network..
As I said when using the same example but from the idf sdk which use the same libraries i think it works just fine.. the networks appear in the app.
https://github.com/espressif/esp-idf/tree/master/examples/provisioning this is the idf example that its working for me
https://github.com/espressif/esp-idf-provisioning-android and this is the app that im using for both examples..
I will do some debug with verbose level tomorrow if i can

I changed the compiler option to verbose and now its scanning and showing the networks

I dont understand what its going on but it is working..

Hello, I can confirm that the Arduino version is not working while the IDF does.
I will take a look into this and try to fix it.
