RPC for AdvaBoard RPi1 / Raspberry Pi RPC

To access the AdvaBoard RPi1 or the Raspberry Pi remotely over a network, RPC (remote procedure call) can be used. This directory contains such a simple example, using the lightweight JSON-RPC.

Server:

The server must be started on a Raspberry Pi.
The example-server can be started by:
```
sudo ./am_rpi_rpc-server.py PORT
```
PORT can be any port, but usually port > 1000 should be used.
All communication is stored in the logfile am_rpi_rpc-server.log, and errors are stored in am_rpi_rpc-server.err. You can use the following commands to start the server and watch the logfile:
```
sudo ./am_rpi_rpc-server.py PORT &
tail -f am_rpi_rpc-server.log
```
Note that the example-server does not use any authentification or encryption, and so should only be used in trusted networks, since anyone on the network can access the Raspberry Pi/AdvaBoard RPi1.

For production use, authentification, encryption and some kind of rights-management-system should be added. Please contact support@advamation.de if you need support for this task.

Client:

The client can be started on any computer, which has a network-connection to the Raspberry Pi, by.

The example-client can be started by:

./am_rpi_rpc-client-example.py IP PORT

where IP must be the IP-address of the Raspberry Pi, and PORT must be the port of the server.

If working correctly, this should print something like:

Connecting to RPC-server on 192.168.178.96:31415...

and the AdvaBoard RPi1-LED should blink afterwards.

Another client is the graphical user-interface, which can be found at ../am_rpi_gui/.
