Communication between devices using a wireless communication protocol

A method for wireless communication between first and second communication devices during connection intervals having a length agreed upon by the first and second communication devices, the method comprising:

• using the first communication device to generate application data;
• using the first communication device to encapsulate the application data in data packets;
• and
• using an antenna of the first communication device to transmit two or more of the data packets during each of one or more of the connection intervals.

A first communication device for communicating wirelessly with a second communication device over a wireless link between the first and second communication devices, the first communication device comprising:

• an application controller configured to generate application data;
• an antenna;
• and
• a wireless communication integrated circuit (IC) configured to (i) receive application data from the application controller, (ii) encapsulate the received application data in data packets, (iii) use the antenna to transmit the data packets, and (iv) during periods when there is no application data to encapsulate and transmit to the second communication device, use the antenna to transmit a message to the second communication device, wherein transmitting the message keeps the wireless link between the first and second communication devices active.
