Dear Tiny OS Profs,
following situation using tinyos 2.0 (one of the old release):
One sender and two receivers are placed very close to each other (~0.5
meter).
Sender transmit packets. Both receivers read rssi values. In general
values are ok and correlate, but sometimes and it is not a singular case
following happens:
one receiver read ~240 the other ~6.
The RSSI is represented in 2's complement:

240 and 6 are not that far apart in this representation.
