Description:

BaseStation is an application that acts as a simple Active Message bridge between the serial and radio links. It replaces the GenericBase of TinyOS 1.0 and the TOSBase of TinyOS 1.1.

On the serial link, BaseStation sends and receives simple active messages (not particular radio packets): on the radio link, it sends radio active messages, whose format depends on the network stack being used. BaseStation will copy its compiled-in group ID to messages moving from the serial link to the radio, and will filter out incoming radio messages that do not contain that group ID.

BaseStation includes queues in both directions, with a guarantee that once a message enters a queue, it will eventually leave on the other interface. The queues allow the BaseStation to handle load spikes more gracefully.

BaseStation acknowledges a message arriving over the serial link only if that message was successfully enqueued for delivery to the radio link.

The LEDS are programmed to toggle as follows:

RED Toggle - Message bridged from serial to radio GREEN Toggle - Message bridged from radio to serial YELLOW/BLUE Toggle - Dropped message due to queue overflow in either direction

When using a CC2420 radio, several default preprocessor configurations are defined in the Makefile:

  • CC2420_NO_ACKNOWLEDGEMENTS
    • Prevents the base station from falsly acknowledging packets
  • CC2420_NO_ADDRESS_RECOGNITION
    • Allows the base station to sniff packets from any transmitter

Other combinations can be defined to meet your application's needs:

  • CC2420_NO_ADDRESS_RECOGNITION only

    • Sniff all packets, but acknowledge packets only if they are sent to the base station's address
  • Removing all preprocessor definitions in the Makefile

    • Only accept packets destined for the base station's address, and acknowledge those packets
