HP (Preamble ID)

This command applies to the XTC RF Module.

Set or read the device's hopping channel number. A channel is one of three layers of filtration available to the device.

In order for devices to communicate with each other, the devices must have the same channel number since each channel uses a different hopping sequence. Devices can use different channels to prevent devices in one network from listening to transmissions of another.

When a device receives a packet it checks HP before the network ID, as it is encoded in the preamble and the network ID is encoded in the MAC header.
