RF Transceiver Application Guide
Some typical applications are described in this section to help user gains more understanding of the operation of the
RF Transceiver.
RF Transceiver Hardware Connection
A typical application connection is shown in Application Circuit section. The MCU host serves as a master role, and the
RF Transceiver serves as a slave role. For more information, refer to the Application Circuit section.
RF Transceiver Initialization
After the RF Transceiver is powered up, some registers need to be configured before the data transmission or recep-
tion. The procedure is described as below.
