2.1.2. Transparent Operation
By default, XBee/XBee-PRO RF Modules operate in Transparent Mode. When operating in this
mode, the modules act as a serial line replacement - all UART data received through the DI pin is
queued up for RF transmission. When RF data is received, the data is sent out the DO pin.
Serial-to-RF Packetization
Data is buffered in the DI buffer until one of the following causes the data to be packetized and
transmitted:
If the module cannot immediately transmit (for instance, if it is already receiving RF data), the
serial data is stored in the DI Buffer. The data is packetized and sent at any RO timeout or when
100 bytes (maximum packet size) are received.
If the DI buffer becomes full, hardware or software flow control must be implemented in order to
prevent overflow (loss of data between the host and module).
2.1.3. API Operation
API (Application Programming Interface) Operation is an alternative to the default Transparent
Operation. The frame-based API extends the level to which a host application can interact with the
networking capabilities of the module.
When in API mode, all data entering and leaving the module is contained in frames that define
operations or events within the module.
Transmit Data Frames (received through the DI pin (pin 3)) include:
" RF Transmit Data Frame
" Command Frame (equivalent to AT commands)
Receive Data Frames (sent out the DO pin (pin 2)) include:
" RF-received data frame
" Command response
" Event notifications such as reset, associate, disassociate, etc.
The API provides alternative means of configuring modules and routing data at the host applica-
tion layer. A host application can send data frames to the module that contain address and payload
information instead of using command mode to modify addresses. The module will send data
frames to the application containing status packets; as well as source, RSSI and payload informa-
tion from received data packets.
The API operation option facilitates many operations such as the examples cited below:
To implement API operations, refer to API sections [p54].
1. No serial characters are received for the amount of time determined by the RO (Packetiza-
tion Timeout) parameter. If RO = 0, packetization begins when a character is received.
2. The maximum number of characters that will fit in an RF packet (100) is received.
3. The Command Mode Sequence (GT + CC + GT) is received. Any character buffered in the
DI buffer before the sequence is transmitted.
-> Transmitting data to multiple destinations without entering Command Mode
-> Receive success/failure status of each transmitted RF packet
-> Identify the source address of each received packet
