11/11/16 - Signal a device
We’ve added the ability to “signal” a device in the Web IDE, under the device details view for any Particle device. Clicking the
Signal button will trigger a rainbow LED pattern on the selected device. You can deactivate the LED pattern once the device is identified by clicking the
Stop signaling button. Note that you can only signal devices that are currently online (breathing cyan dot next to the device name).
This is useful when you want to flash firmware to a particular device that you have forgotten the name of, or testing if a device is responding to incoming messages despite it showing the cyan RGB led (online).
