To clarify, are you saying that you couldn't connect to WiFi before you completely erased flash? Yes, exactly that's it. It seems that the esp32 development kit boards have been preflashed with an older sdk version. Thus it is necessary to erase all data in flash to get a newer app working. See htt...

After some tests I found out, that it is necessary to fully erase the flash memory by issuing the command ~/esp/esp-idf/components/esptool_py/esptool/esptool.py --port /dev/ttyUSB0 erase_flash Now make flash works properly.

I don't think this brings you up to the master (at least in the recursively fetched remote repositories).

Hi Malte,

thank you very much for your help - it works now! Originally I followed the instructions in https://github.com/espressif/esp-idf/bl ... -setup.rst
Why did nobody tell that the SDK is broken currently?

Checked out everything again and still there is no difference.

Even this very simple ssid and password does not work:
.ssid = "test",
.password = "12345678",
.bssid_set = false

Hi,

I tried WPA2 with two different access points:
- Fritz!Box 7490
- Raspi with hostapd

Further I tried an Android device (Oneplus 3 running Android 7.0) in wifi hotspot mode with and without any encryption.

All without any success.

Same results here with three modules:

- two of type 'ESP32_Core_board_V2'
- one of type 'ESP32 DEVKIT V1' by www.doit.am

connected via USB to a MacbookPro. All git-repositories are up to date. Build was done under Ubuntu 16.04.1 running in a parallels VM.

Any help is appreciated.
