Power Management
The module can be set in SLEEP mode in order to reduce the power consumption.
The low power SLEEP mode is entered by using the SLEEP command ‘Z’. In sleep mode the
module will not receive or detect incoming data, neither from the host (UART port) nor from
the RF transceiver. The module is awakened from the SLEEP mode by sending a wake-up
byte on the UART RXD line. The wake up byte should be FFh. After the module has awaken
(see Timing Information) it is ready to receive data on the UART or from the RF transceiver.
All configuration settings and RAM values are retained during Sleep.
If the module is shut completely off, all configuration settings in non-volatile memory is
restored, but values in RAM are overwritten with default settings.
