*Duty cycle is a function of the number of bytes in the RF packet and the data rate
**Maximum number of bytes in RF packet to comply with 30% duty cycle limit
Power Modes
The module can be set to sleep mode to reduce the power consumption. Sleep mode can be enabled by driving CONFIG low and sending
a “Z” command. The module is woken up when CONFIG is driven high.
