Bluetooth Low Energy / Mbed 2 deprecated BLE_Thermometer Featured

BLE demo for the Health-Thermometer service.

Dependencies:   BLE_API mbed nRF51822 X_NUCLEO_IDB0XA1

This example demonstrates how to use the Health Thermometer Service. The Health Thermometer service reports two pieces of information, Temperature and Sensor Location.

API

Import library
BLE_API - HealthThermometerService Class Reference

Public Types

enum SensorLocation_t {
LOCATION_ARMPIT = 1, LOCATION_BODY , LOCATION_EAR , LOCATION_FINGER ,

}

Public Member Functions

HealthThermometerService ( BLE &_ble, float initialTemp, uint8_t _location)
Add the Health Thermometer Service to an existing BLE object, initialize with temperature and location.
void updateTemperature (float temperature)
