esp32s3 wifi

[Afzal H. Khan]

Dear Experts ,
Recently we have been working with esp32s3 ( FREENOVE ESP32-S3-WROOM ) where esp32s3 is creating wifi ( ap ) network and android/iPhone is getting connected to that network. iPhone/android is supposed to get data from esp32s3 through wifi network and use cellular data for internet . The issue is , in case of iPhone , after getting connected to esp32s3 wifi , it does not switch to cellular for internet automatically .
Please help us to know if any wifi configuration is missing at esp32s3 end which causes this issue .
We are using ESP-IDF v5.2.1 and soft AP for wifi .
Thanks in advance .

On the iPhone, check the network settings to see if it's set to automatically switch to cellular data when the WiFi network has no internet access.

It helps to adjust your DHCP server (running on the ESP32) to not hand out a gateway. iPhone will then instantaneously understand that there is no internet connectivity towards this AP and will use cellular for every communication not targetted at your AP's subnet.
