Ro (Packetization Timeout); Api Enable; Nb (Parity); Pr (Pull-Up/Down Resistor Enable) - Digi XBee User Manual

AT commands

RO (Packetization Timeout)

Set or read the number of character times of inter-character silence required before transmission.
RF transmission starts when the device detects data in the DI (data in from host) buffer and RO
character times of silence are detected on the UART receive lines (after receiving at least 1 byte).
RF transmission also starts after 100 bytes (maximum packet size) are received in the DI buffer.
Set RO to 0 to transmit characters as they arrive instead of buffering them into one RF packet.
Parameter range
0 - 0xFF (x character times)
Default
3

API Enable

Disable or Enable API mode to operate using a frame-based API instead of using the default
Transparent (UART) mode. For more information, see
Note Minimum firmware version required: 1.x80. Firmware versions are numbered in hexadecimal
notation.
Parameter range
0 - 2
Parameter

2
Default
0

NB (Parity)

The device does not actually calculate and check the parity. It only interfaces with devices at the
configured parity and stop bit settings.
Parameter range
0x00 - 0x04
Default
0x00

PR (Pull-up/Down Resistor Enable)

The bit field that configures the internal pull-up resistor status for the I/O lines.
PR and PD only affect lines that are configured as digital inputs or disabled.
