Send Sensor Readings to Android Phone using Arduino and NRF24L01 via BLE
In this tutorial, we will learn how to send sensor readings to an Android phone using Arduino nRF24L01+ module, and BLE. The transfer of data will be through Bluetooth Low Energy (BLE). We will use DHT22 sensor to access current temperature readings and send them to our android phone using nRF24L01+ RF module that we … Read more
