Supported Transceivers

This adaption layer is written to be used by CC110x and CC1200 transceivers, but any transceiver using layer 2 addresses which are 1 byte in size would likely be able to use it. Keep in mind that both CC110x and CC1200 are able to transmit frames of up to 255 bytes (thus 253 bytes of payload, as the layer 2 header is 2 bytes in size). Other transceivers only supporting smaller frames may not be able to use all the upper layer protocols supported by the CC110x and CC1200 transceivers.

Field Description
Destination The layer 2 destination address
Source The layer 2 source address
Payload The payload (variable size)

Layer 2 Broadcast

This adaption layer assumes that the layer 2 address 0x00 (see CC1XXX_BCAST_ADDR) is reserved for layer 2 broadcast, which is true for CC110x and CC1200 transceivers (provided they are configured accordingly). If more users of this adaption layer are added, this behaviour might needs to be more generalized.
