Overview#
This application implements the central role. It:
Scans for the health_care_iot_peripheral device or the health_care_iot_hub device.
Connects to it
Pairs with it
Enables temperature indications
Prints the reported temperature each time an indication is received
Running the demo#
The central app will now autonomously scan.
The central app will only connect to nearby devices with a RSSI value > PROXIMITY_RSSI_THRESHOLD
Once a connection is set up with a nearby device, pairing procedure is automatically initiated
The output of the central app looks like:
