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.

Commit message:
update mbed-os so both NNN50 and NQ620 (as well as NQ624 module) platform are supported; Add config in mbed_app.json to fix NQ620 use internal RC issue ; remove the unused shield folder;update BLE_API;Modify SCL/SDA pin
