Event data that is sent from Amarino is structured so that it can be
easily identified and parsed by Arduinos. Each event type is
associated with a single alphanumeric character that uniquely
identifies the event. For example, the Battery Level event is
associated with the character ‘J’. Event data packages contain the
identifier character followed by the relevant event data. A
Battery Level event, for example, would consist of the character
‘J’ followed by a number from 0-100 that indicates the phone’s
current battery level.
