hi to the community. Looking to setup a small project for my self. I want to give to a small board project power between 10-32V and be able to transmit that power readout from battery as data value as notifications to a mobile or tablet through a local wifi network as bluetooth is not so strong. Not into electronics but i want to try and test my self.
suggest ESP32 which has onboard WiFi, Bluetooth Classic and BLE
you could connect to the Smartphone using Bluetooth Classic (simplest) or BLE
also you would have the ability to connect to local WiFi if every required (note cannot use Bluetooth and WiFi at the same time)
