AT commands
NB (Parity)
Set or read the serial parity settings for UART communications.
Parameter range
0x00 - 0x04
Parameter
0x00
0x01
0x02
0x03
0x04
Default
0x00
RB (Packetization Threshold)
Sets or displays the character threshold value.
RF transmission begins after a device receives data in the DIN buffer and meets either of the following
criteria:
The UART receives RB characters
n
The UART receive lines detect RO character times of silence after receiving at least 1 byte of
n
data
If a device lowers PK below the value of RB, RB is automatically lowered to match the PK value.
If RO = 0, the device must receive RB bytes before beginning transmission.
RB and RO criteria only apply to the first packet of a multi-packet transmission. If data remains in the
DIN buffer after the first packet, transmissions continue in a streaming manner until there is no data
left in the DIN buffer.
Parameter range
1 - 0x100 (bytes) (Maximum value equals the current value of PK Parameter (up to 0x100 HEX (800
decimal))
Default
0xD3
RO (Packetization Timeout)
Set or read the number of character times of inter-character silence required before transmission
begins. For information on how RO works with the RB command, see
Parameter range
0 - 0xFF [x UART character times]
