Digi XBee® 3 802.15.4 RF Module User Guide
149
Parameter
Configuration
0
One stop bit
1
Two stop bits
Default
0
FT (Flow Control Threshold)
Set or display the flow control threshold.
The device de-asserts CTS when
FT
bytes are in the UART receive buffer. It re-asserts CTS when less
than
FT
bytes are in the UART receive buffer.
Parameter range
0x20 - 0x1B0 bytes
Default
0x158
RO (Packetization Timeout)
Set or read the number of character times of inter-character silence required before transmission
begins when operating in Transparent mode.
Set
RO
to 0 to transmit characters as they arrive instead of buffering them into one RF packet.
The
RO
command only applies to Transparent mode, it does not apply to API mode.
Parameter range
0 - 0xFF (x character times)
Default
3
AP (API Enable)
Set or read the API mode setting. The device can format the RF packets it receives into API frames
and sends them out the serial port.
For more information, see
When you enable API, you must format the serial data as API frames because Transparent operating
mode is disabled.
Parameter range
0 - 2
Parameter
Description
0
API disabled (operate in Transparent mode)
