AT commands UART interface commands
Digi XBee3® 802.15.4 RF Module User Guide
100
Parameter Configuration
0 One stop bit
1 Two stop bits
Default
0
FT command
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
0x0C - 0xA2 bytes
Default
0x81
RO command
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
APcommand
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 Serial modes.
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)
