RB (Packetization Threshold)

This command applies to the XTC RF Module.

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
• The UART receive lines detect RO character times of silence after receiving at least 1 byte of 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.
