# 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 library is used to simplify access to the Bluetooth Low-Energy
|
||
|
|
hardware. If you need to re-compile the Blessed library for any reason, you
|
||
|
|
can use `go generate` from the `depjars` directory. To do that, you will need
|
||
|
|
to have `gradle`, an Android SDK, and who knows what else installed on your
|
||
|
|
machine.
|
||
|
|
|
||
|
|
## 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
|
||
|
|
```
