README for TestIndirect
Author/Contact: Jan Hauer <hauer@tkn.tu-berlin.de>

Description:

In this application one node takes the role of a PAN coordinator in a
beacon-enabled 802.15.4 PAN, it transmits periodic beacons and additionally in
every beacon interval it tries to transmit one DATA frame to a device using
indirect tranmission. A second node that takes the role of a device first scans
the pre-defined channel for beacons from the coordinator and once it finds a
beacon it tries to synchronize to and track all future beacons. Whenever the
coordinator has data to send (indicated in the beacon), the device extracts the
DATA frame from the coordinator.

Criteria for a successful test:

Both nodes should toggle the LED1 in unison, about once every half second. 
The coordinator should also toggle LED2 with the same frequency.


Tools: NONE

Usage: 

1. Install the coordinator:

    $ cd coordinator; make <platform> install

2. Install one device

    $ cd device; make <platform> install

You can change some of the configuration parameters in app_profile.h

Known bugs/limitations:

- Many TinyOS 2 platforms do not have a clock that satisfies the
  precision/accuracy requirements of the IEEE 802.15.4 standard (e.g. 
  62.500 Hz, +-40 ppm in the 2.4 GHz band); in this case the MAC timing 
  is not standard compliant
