We wish to add some form of remote control interface to LIAM.
Modularity is important. This should in no way be required for normal operation.
We want a simple interface with remote modules plugging in to the "bluetooth" port of the top shield to handle the external communication. This requires a serial interface.
The interface(s) should be able to:
Report status (Battery, operation mode, errors)
Change the operation mode of the mower
Be human readable (to an extent - e.g. B:11998;M:2;E:0 is ok, binary data is not)
