AT commands
Parameter
0
1
Default
0
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.
Parameter range
0 - 0xFF (x character times)
Default
3
FT (Flow Control Threshold)
Set or display the flow control threshold.
The device de-asserts CTS and/or send XOFF when FT bytes are in the UART receive buffer. It re-
asserts CTS when less than FT-16 bytes are in the UART receive buffer.
Parameter range
0x11 - 0x16F bytes
Default
0x13F
AP (API Mode)
Set or read the API mode setting. The device can format the RF packets it receives into API frames
and send them out the serial port.
Parameter range
0 - 2
Parameter Description
Transparent mode, API mode is off. All UART input and output is raw data and the
0
device uses the RO parameter to delineate packets.
1
API Mode Without Escapes. The device packetizes all UART input and output data in API
format, without escape sequences.
