Health Thermometer API#

API for the Health Thermometer GATT service This is a Low-Code component. At start, the temperature sensor has to be initialized. Once the BLE connection is established, the sl_bt_ht_temperature_measurement_indication_changed_cb() function will be called where either a single measurement can be done, or a timer started. A reference implementation for this function can be found in Bluetooth - SoC Thermometer example, in app.c file. The result of the measurement can be send using sl_bt_ht_temperature_measurement_indicate() function.
