Implementation of SimpleBLE (https://github.com/OpenBluetoothToolbox/SimpleBLE) as a GDNative plugin for Godot 3.5 (WIP), is a part of GDWired (https://github.com/GDWired). Godot4 related work are in the branch godot4 (WIP).
The project works on
- macOS : Good
- Linux : Good but, if the scan is active, the connection/disconnection doesn't work well (seems not completely stable, many warnings)
- Windows : Good
Exports from Godot work for all platform except for iOS (WIP), SimpleBLE is not yet available for Android.
Dependencies:
- Godot build dependencies (https://docs.godotengine.org/en/stable/development/compiling/index.html)
- cmake
- [Linux] lib dbus devel (sudo apt install libdbus-1-dev or equivalent)
To compile it:
- Run
git clone --recurse-submodules [email protected]:GDWired/GDSimpleBLE.git - Run
scons target=releaseon the root folder.
In the "demo" folder there is a sample project, after compiling the project you can open it with Godot 3.5.1. (You can also download a precompiled version of the plugin from the asset store or in the release section of github WIP)
First line:
- Scan: start/stop the scan
- Connect/Disconnect: connect or disconnect the device (the address used is the first one on the left).
- Infos: get information about the device, manufacturer data and list of services -> characteristics -> descriptors (the address used is the first address on the left).
- Clear: clear the terminal and delete all peripherals
- Update: enable/disable the display of updates
- Advance: enable/disable the display of devices without identifiers and/or devices that cannot be connected
Second line:
- First input line (left): device address
- Second input line (middle): service address
- Third input line (right): feature address
Third line:
- Notify: try to notify the service/characteristic.
- Read: try to read the service/characteristic.
- Send: try to write in the service/characteristic.
- Last input line: data to be sent when the "Send" button is pressed
À Bloc Attaque is a cycling game that connects to, and is controlled by your smart cycling trainer. Unlike other applications focusing on the social and competitive aspects of gamified indoor training, ABA focuses on adventure, mood and solitary efforts. Set somewhere in the 1950's French countryside, your task is to literary "fight the road".
