Hi JColvin - thanks for your reply.
The Wifi network is on 2.4GHZ, with a hidden SSID.
We are following the instruction for AT+CWJEAP=<ssid>,<method>,<identity>,<username>,<password>,<security>[,<jeap_timeout>]
and sending the following command (PASSWORD replaces the actual strong pwd):
AT+CWJEAP="CHRH_WIFI",1,"equinox","equinox","PASSWORD",
We immediately get this strange/undocumented error 0x0109000 which is not found under Wi-Fi AT Commands - ESP32 - — ESP-AT User Guide latest documentation (espressif.com)
Could you perhaps test on your local office enterprise WPA2? I only have it available at the customer..
Many thanks. Bart
