Future Electronics / Mbed OS sequana-ble-HeartRate

This is a fork of mbed-os-example-ble-HeartRate maintained for Sequana compatibility. This application transmits a heart rate value using the Bluetooth SIG Heart Rate Profile. The heart rate value is provided by the application itself, not by a sensor, so that you don't have to get a sensor just to run the example. The canonical source for this example lives at https://github.com/ARMmbed/mbed-os-example-ble/tree/master/BLE_HeartRate
