XBee‐PRO® XSC OEM RF Modules
2.2. Modes of Operation
2.2.1. Idle Mode
2.2.2. Transmit Mode
XBee-PRO® XSC RF Modules operate in five modes.
Figure 2‐04. Modes of Operation
When not receiving or transmitting data, the RF module is in Idle Mode. The module shifts into the
other modes of operation under the following conditions:
When the first byte of serial data is received from the UART in the DI buffer, the module attempts
to shift to Transmit Mode and initiate an RF connection with other modules.
Figure 2‐05. Transmission of Data
Once in Transmit Mode, the module initializes a communications channel. Channel initialization is
the process of sending an RF initializer that synchronizes receiving modules with the transmitting
module. When streaming multiple RF packets, the RF Initializer is only sent in front of the first
packet. During channel initialization, incoming serial data accumulates in the DI buffer.
After the channel is initialized, data in the DI buffer is grouped into packets (up to 64 bytes in each
packet) and is transmitted. The module continues to transmit data packets until the DI buffer is
empty. Once transmission is finished, the module returns to Idle Mode. This progression is shown
in Figure 2-05.
As the transmitting module nears the end of the transmission, it inspects the DI buffer to see if
more data exists to be transmitted. This could be the case if more bytes arrived from the host
after the transmission began. If more data is pending, the transmitting module assembles a
subsequent packet for transmission.
