i can see the lisr of available wifi networks in serial monitor.
then i try to connect to my home wifi in 2.4g but it wont work.
i also tried to connect to a phone hotspot just next to the module. (even without any security.. no password)
the monitors tells me all the time the following :
Starting WiFi connection...
Scanning for WiFi networks...
Available Networks:
1: Redmi (Signal: -24 dBm) (Open)

Is there anything im doing wrong, im basically doing the wifi connection as in the video transmission example :
https://wiki.dfrobot.com/SKU_DFR1154_ESP32_S3_AI_CAM#target_7
or more verbose helped by chat GPT but doing the same.
Any ideas ?
I have done some more testing and can confirm that I can establish the connection (as a station to the access point) with WLAN channel less than 11 (with and without password). But the connection doesn't seem stable! Once the connection and URL are displayed in the serial monitor, access in the browser (or via CURL) isn't possible. Further tests have shown that the WLAN connection is interrupted (at different times). When the ESP is operated as an access point, the WLAN connections are more stable.
Lupin It is the same issue for me, too! I have tried to connect to different Wi-Fi 2.4G - no success.
Peter.Usov Same issue for me! I followed all steps on Wiki (https://wiki.dfrobot.com/SKU_DFR1154_ESP32_S3_AI_CAM) and tried with different AP's (Router and iPhone Hotspot) … the only output on serial is: WiFi connecting ………..
