Digital radio communication
First Claim
1. A method of digital radio communication between a first device and a second device, each comprising a radio transmitter and a radio receiver, the method comprising:
- a) said first and second devices establishing a connection using a predetermined protocol having at least one predefined message format;
b) if said connection is subsequently broken, said second device transmitting an advertising message at a first data rate indicating a desire to reconnect;
c) if a reconnection is not established, said second device transmitting a further advertising message at a second data rate indicating a desire to reconnect, wherein said second data rate is lower than the first data rate; and
d) the first and second devices conducting subsequent communication at a data rate applied to the advertisement message received by the first device in order to establish the reconnection.
