Hello everyone i have a project on stm32f411 nucleo board 64 i ve done the C coding i am looking for someone familiar with stm projects as soon as possible

We have some existing code which we are using for prototyping some IoT devices. At the moment the code is compiled using Arduino IDE with WiFi credentials hard coded into the ESP32. We require the code modified to allow the WiFi credentials to be modified by using a mobile phone after the code is compiled.

I need some body expert in Esp32 and App inventor. I any has this this experience chat please
