Certain data packets for transmission between a first device and a second device may have an importance that changes depending on different circumstances. After the data packet is initially communicated from the first device to the second device, if an acknowledgement is not received at the first device, the first device may retransmit the data packet. If no acknowledgement is received after a certain period of time, communication of the data packet may be considered to have a lower importance, and so additional retransmissions bay be delayed until a retransmission trigger is identified. Examples of such a trigger may be powering on of an antenna for a second different data packet transmission, or identification that a subsequent data packet was successfully received by the second device.
