We are developing a device with a built-in wifi module and a system that allows you to change the settings of that device from your iPhone via wifi.
When iPhone 16.4.1 connecting to the access point of the wifi module, the connection between the terminal and the wifi module was often interrupted.
At that time, the wifi module access point is listed as "No internet Connection" on the wifi setting screen of the iPhone.
There was no interruption on devices prior to 16.4.1, and after updating to 16.4.1(a), there was no interruption.
Can anyone tell me why there was an interruption in 16.4.1, and why the interruption disappeared after updating?
