WE just bought 10 of these devices for a project we are developing and we are having an issue connecting to our 2Ghz Wifi. When we turn on debugging we get the following

rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

flash read err, 1000

What kind of wireless security are your access points using?

The error doesn’t really tell me much but I’m wondering if you have the password wrong in the sketch or your access point is using a form of encryption the ESP32 can’t connect to.

We get the same message if the password is correct or wrong.

We use WPA/WPA2 security.

As for Access point we use:

Ubiquiti Networks Unifi 802.11ac Dual-Radio PRO Access Point (UAP-AC-PRO-US)

When we do a network scan with the device it sees our network (1st Entry) SSID and 30 others

For whatever reason, the access point is kicking the Thing off the network. I don’t know why it’s doing that but you might check your logs to see if the access point gives a reason why it’s not wanting to connect.
