For situation 2 above you should configure the SPOT as a dedicated mesh router, using the
command:
ant selectmeshrouter
When the SPOT is reset (by pressing the attention button or by an
ant run
command) it will begin
acting as a dedicated router. A SPOT set in this configuration does not need the
spot.mesh.enable
property to be set.
Trace route
A SPOT can optionally run a trace route server. If a SPOT is running the trace route server it can
participate in route tracing requests. The default is for the server not to run. To enable the server set
the system property
spot.mesh.traceroute.enable
to true, like this:
ant set-system-property –Dkey=spot.mesh.traceroute.enable –Dvalue=true
You should then see the server indicate its presence at start-up, like this:
[TraceRouteServer] starting
If you have a number of SPOTs running the trace route server you can issue trace route requests,
like this:
ant tracert -DremoteId=
0014.4F01.0000.0006
which will trace the current route to the specified SPOT.
Logging
As a diagnostic aid, you can enable display of all network route discovery and route management
activity. To do that, set the system property
spot.mesh.route.logging
to true, like this:
ant set-system-property –Dkey=spot.mesh.route.logging –Dvalue=true
To see the same diagnostics for host applications, use:
ant host-run –Dspot.mesh.route.logging=true
See also the section below “Adjusting Log Output” for information on controlling whether opening
and closing connections will be logged.
Hardware configurations and USB power
The SPOTs in the development kit come in two configurations:
SPOT + battery + demo sensor board
SPOT only
The SPOT-only package is intended for use as a radio base station, and operates on USB-supplied
power. Apart from the lack of battery and sensor board the base station SPOT is identical to other
SPOTs.
SPOTs are expected to work in a battery-less configuration (powered by USB power) if they do not
have any other boards (such as the demo sensor board) fitted. If other boards are fitted the power
consumption may exceed the maximum permitted by the USB specification. This is especially
