ZRC provide a simple API for bluetooth wireless control.
Write 2 Bytes payload to ATT handle 0x26, ZRC will send out IR code as if some button been pressed.
| Index | Value | Description |
|---|---|---|
| 0 | 0x02 | Command Code |
| 1 | Button Number | 00 - Digit 0, 01 - Digit 1, ... |
Prerequisite
- ZRC been configured.
- Make sure press button can control the device.
- Disconnect from FzRemote App.
- Bluetooth peripheral can have only one connection, disconnect from FzRemote App so that Raspberry Pi can connect to it. You can take iPhone far alway from the remote control, or you can kill the App.
- Bluetooth up and running on Raspberry Pi.
- Note - Old Raspberry Pi have no build-in bluetooth, USB bluetooth 4.0 adapter required in that case.
Scan to find out mac address.
