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
