2 Basic Functionality
The figure below shows a simplified block diagram of the module:

– Block diagram
The host use the UART Interface to send and receive data. The UART packet content, like the addition of RSSI,
CRC and start/stop bytes, can be changed in the configuration mode.
When the module receives a packet with correct destination address over RF it will send the packet over the UART
interface on the TXD line. When the host MCU wants to transmit a packet over the RF, it must send the packet
through the UART interface on the RXD line.

The addressing scheme provide point to opint and point to multipoint (broadcast) options.
