# HRM

|
An example heart rate monitor app for Android and MacOS using [git.wow.st/gmp/ble](https://git.wow.st/gmp/ble) and [Gio](https://gioui.org).
|
||
|
|
|
||
|
|
The MacOS implementation uses a Core Bluetooth binding created by
|
||
|
|
[NSWrap](https://git.wow.st/gmp/nswrap). On Android, Martijn van Welie's
|
||
|
|
[Blessed](https://github.com/weliem/blessed-android) library is used to
|
||
|
|
simplify access to the Bluetooth Low-Energy hardware.
|
||
|
|
|
||
|
|
## MacOS:
|
||
|
|
|
||
|
|
```
|
||
|
|
git clone https://git.wow.st/gmp/hrm
|
||
|
|
cd hrm/hrm
|
||
|
|
go build
|
||
|
|
./hrm
|
||
|
|
```
|
||
|
|
|
||
|
|
## Android:
|
||
|
|
|
||
|
|
The `gogio` command from `gioui.org/cmd/gogio` must be installed to build
|
||
|
|
an Android APK.
|
||
|
|
|
||
|
|
```
|
||
|
|
git clone https://git.wow.st/gmp/hrm
|
||
|
|
cd hrm/hrm
|
||
|
|
gogio -target android .
|
||
|
|
adb install -r hrm.apk
|
||
|
|
```
|
||
|
|
|
||
|
|
The compiled Java code for the Android implementation is pre-packaged in
|
||
|
|
jar files. If you want to, you can re-compile these dependencies by running
|
||
|
|
`go generate` from the `depjars` directory. You will need to have `gradle`,
|
||
|
|
an Android SDK, and who knows what else installed on your machine.
