Connecting multiple(up to 9) ESP32 with a andriod phone via bluetooth and wi-fi

I need an experienced programmer in ESP32, bluetooth and RTOS for connecting 6-9 ESP32 devices to android and iphone simultaneously via bluetooth and Wi-fi. The devices should connect seamlessly just like headphone connect to our phone.

Data to be sent and received after connection is established:

1. From phone to ESP32s: ON command (make a digital pin High to turn on a relay connected at the end of it)

2. From ESP devices: From ESP devices, once ON command is received, a timer will start. There is a OFF switch connected to one of the GPIOs which will turn off the timer and send timer value to the mobile.

The application running on phone does not need to have high level GUI. a basic one will also do. Functionality is more important.

I would prefer someone who can come down to Pune at our office in Kothrud. But if you are good enough,

The hardware will be available for remote access if it is possible.

Kĩ năng: Android, Bluetooth ít năng lượng (BLE) , Embedded Systems, Phần mềm cài sẵn, Internet of Things (IoT)
