7.2.2.9
Get PAN Scan (0x08)
Returns a list of PAN-Descriptor structures for every PAN Coordinator discovered during a scan of all
channels.
Energy scan may not detect adjacent 802.15.4 networks that are configured for beacon-less operation.
PAN scan broadcasts a beacon request on all enabled channels and generates a list of PAN-Descriptors
for every PAN Coordinator that responds. During network commissioning, the Host CPU can use the
PAN-Descriptor list to identify a suitable channel for the new PAN.
The format of the PAN-Descriptor structure is a subset of the full TIMAC descriptor.
Returns Acknowledge = zero(0) (NAK) in its Command Byte and Length = 0 if radio busy scanning.
Length = 1 indicates PAN scan completed, but no PAN Coordinators detected.
