Abstract
The invention relates to a method for wireless transmission of data between components of a blood glucose system including a master controller (i.e., “master”) and a slave device (i.e., “slave”). The master and slave each have a receiver and transmitter. The method comprises operating the slave normally in a power saving mode, activating the transmitter of the master for a transmission period and subsequently activating the receiver of the master for a response period. When the slave receives a preamble signal during a listening period the slave receiver is activated until a portion of a transmitted data frame from the master is received, switched into a communication mode to transmit a response to the master and switched from the communication mode to the power saving mode. In the power saving mode the activation frequency of the slave receiver and the transmission of the data frame are controlled to save power.
