A system and method for processing instructions sent wirelessly between a control master unit and a slave device comprising a slave device memory is disclosed. The control master unit transmits an instruction to the slave device. The slave device writes the received instruction to the slave device memory; reads a stored instruction, corresponding to the instruction written to the memory, from the memory; and transmits the stored instruction to the control master unit. The control master unit compares the stored instruction to the instruction and, if the stored instruction is the same as the instruction, enables a process instruction to be sent to the slave device. In response to receiving the process instruction, the slave device processes the stored instruction.
