PK (Maximum RF Packet Size)

This command applies to the XTC RF Module.

Sets or displays the maximum size of RF packets that a device in Transparent operating mode (AP = 0) transmits. You can use the maximum packet size along with the RB and RO parameters to implicitly set the channel dwell time.

If you set PK above 256 and subsequently change BR to 0, PK lowers to 256 and issues a warning. For more information, see BR (RF Data Rate) and WN (Warning Data).

Changes to the PK parameter may have a secondary effect on the RB (Packetization Threshold) parameter. RB must always be less than or equal to PK. If you change PK to a value that is less than the current value of RB, the RB value lowers to be equal to PK.
