Delta / Mbed OS BLE_HTS_Demo

BLE_HTS_Demo

This BLE_HTS_Demo program enables you to collect Temperature and Humidity data reading from sensor and transmit to collector device such as smartphone.

Below documents teach you how to install app that can connect and read data from our DELTA-DFCM-NNN40 development board. There are two versions, Android and iPhone.
