A method for wireless transmission of data between components of a blood glucose system including a master controller having a receiver and a transmitter and a slave device having a receiver and a transmitter, the method comprises the steps of: setting a sniff interval for the slave device to a first sniff interval; determining whether a preamble data transmission is received within a first interval; in the event the determining step is true, evaluating whether a remainder of the data frame is a communication initiation data frame and deciding whether an address portion of the data frame includes an address of the slave device; in the event the evaluating step or the determining step is false, deactivating the receiver of the slave; and in the event the deciding step is true, deactivating the receiver of the slave device and switching the slave device to a communication mode such that the transmitter of the slave device is activated to transmit a response to the master controller and then the receiver of the slave device is again activated to wait for further data frames from the master controller.
