3. Frame Format

TinyOS has two 802.15.4 frame formats. The first format, the T-Frame, is for TinyOS networks which do not share their channel with other wireless -networking archtiectures. This frame format assumes that TinyOS can use +networking architectures. This frame format assumes that TinyOS can use every bit of the packet and does not need to state that it is a TinyOS packet. T-Frame stands for "TinyOS Frame."

The TinyOS 802.15.4 T-frame format is as follows:

AM type is the same as in a T-frame. 6lowpan is the IANA-assigned code -to identify this as a TinyOS packet. At this time, the exact value of -this code has not been determined. To inform 6lowpan that this is not -a 6lowpan packet, the code used MUST be in the range of 192-55.

The AM type 6lowpan is reserved. A TinyOS program MUST NOT use it.

AM type is the same as in a T-frame. 6lowpan is the NALP code to identify +this as a TinyOS packet. NALP codes must be in the range of 0-63. +TinyOS uses code 63.

The AM type 63 is reserved for both T-Frames and I-Frames. A TinyOS +program MUST NOT use it.

4. Implementation

An implementation of the T-Frame can be found in tinyos-2.x/tos/chips/cc2420.

An implementation of the I-Frame will soon be found in -tinyos-2.x/tos/chips/cc2420.
