jonaangelica 0:cc636f742803 1 # BLE Heart Rate Monitor
jonaangelica 0:cc636f742803 2
jonaangelica 0:cc636f742803 3 This application transmits a heart rate value using the [Bluetooth SIG Heart Rate Profile](https://developer.bluetooth.org/TechnologyOverview/Pages/HRP.aspx). 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.
jonaangelica 0:cc636f742803 4
jonaangelica 0:cc636f742803 5 Technical details are better presented [in the mbed Classic equivalent of this example](https://developer.mbed.org/teams/Bluetooth-Low-Energy/code/BLE_HeartRate/).

jonaangelica 0:cc636f742803 9 ## Requirements
jonaangelica 0:cc636f742803 10
jonaangelica 0:cc636f742803 11 To see the heart rate information on your phone, download Panobike for [iOS](https://itunes.apple.com/gb/app/panobike/id567403997?mt=8) or [Android](https://play.google.com/store/apps/details?id=com.topeak.panobike&hl=en).
jonaangelica 0:cc636f742803 12
jonaangelica 0:cc636f742803 13 You could also use a generic BLE scanners:
jonaangelica 0:cc636f742803 14
jonaangelica 0:cc636f742803 15 - [nRF Master Control Panel](https://play.google.com/store/apps/details?id=no.nordicsemi.android.mcp) for Android.
jonaangelica 0:cc636f742803 16
jonaangelica 0:cc636f742803 17 - [LightBlue](https://itunes.apple.com/gb/app/lightblue-bluetooth-low-energy/id557428110?mt=8) for iPhone.
jonaangelica 0:cc636f742803 18
jonaangelica 0:cc636f742803 19 Hardware requirements are in the [main readme](https://github.com/ARMmbed/mbed-os-example-ble/blob/master/README.md).
jonaangelica 0:cc636f742803 20
jonaangelica 0:cc636f742803 21 ## Building instructions
jonaangelica 0:cc636f742803 22
jonaangelica 0:cc636f742803 23 Building instructions for all samples are in the [main readme](https://github.com/ARMmbed/mbed-os-example-ble/blob/master/README.md).

jonaangelica 0:cc636f742803 25 ## Checking for success
jonaangelica 0:cc636f742803 26
jonaangelica 0:cc636f742803 27 **Note:** Screens captures depicted below show what is expected from this example if the scanner used is *nRF Master Control Panel* version 4.0.5. If you encounter any difficulties consider trying another scanner or another version of nRF Master Control Panel. Alternative scanners may require reference to their manuals.
jonaangelica 0:cc636f742803 28
jonaangelica 0:cc636f742803 29 1. Build the application and install it on your board as explained in the building instructions.
jonaangelica 0:cc636f742803 30 1. Open the BLE scanner on your phone.
jonaangelica 0:cc636f742803 31 1. Start a scan.
