Yesterday I tried made a little test on mesh networking, how it works,
what the ranges are, etc. I basically used the MultihopOscillator sample
for this, as I understand that uses the Collection feature (TEP 119)
I had a very minimalistic setup:
mote 0 - the 'base station', connected to my laptop via USB
mote 1 & mote 2 - two sensor motes
the setup I tried to achieve was that I'd measure the wireless range of
a mote, and then make it so that mote 0 and 1 are within range, mote 1
and 2 are also in range, but mote 0 and 2 are not:
|--------range---------|
|--------range---------|
mote0 mote1 mote2
the rationale is that this way, the mesh-networking feature has to kick
in, and mote2 should send readings to mote0 via mote1
unfortunately, this is not what happened. as I moved mote2 out of range
from mote0, basically mote0 readings were not received anymore. when
looking at it, mote2 started to show error (the red led started to turn
on, and MultihopOscilliscope is written in the way that this signals an
error)
was my assumption bad? is this not the way things should work? am I
missing something?
