An event-based Python library for TCP communication between multiple devices.
The goal of this was to be easy to use, reliable and applicable to different computers.
The library has been reliably tested with 3 Unix devices in the pipeline
- PC acting as the server
- Raspberry Pi 3 as a client issuing commands
- Lego Mindstorm EV3 receiving commands and controlling a robot
This is implimented via 2 different calsses - TCPServer and TCPClient. There always must be at least one server, but you can have multiple clients. Actions are triggered on state changes when given a callback function. Naturally, the server must be started first before any other clients
For simplicity the library was chosen to be event-based with 4 differnt events:
LISTENING- waiting for another device to connectCONNECTED- another device has successfully connected.MESSAGE- a message has been receivedDISCONNECTED- all devices have been disconnected
The library itself is contained in the tcpcom.py and there are 2 examples usages in server.py and client.py.
** The library also impliments a useful debug mode which can be enabled via the isVerbose flag on class initlisation. **
