Designing router using multiple transceivers

Other Parts Discussed in Thread: CC2520, CC2530

Hi,

I want to design a router having 2 transceivers. I am planning to use CC2530 + CC2520 (connected at SPI port P1_2 to P1_5 of CC2530), which port I shall use for CC2520 interrupts?

Looking forward to your guidelines, which we shall consider while designing.

Thanks and regards,

Praveen

    Hi,

    as you know CC2530 and CC2520 have the same radio, except that the CC2530 has also an integrated micro-controller.

    May I ask why you need to transceiver in your design?

    If it is to run a dual PAN based stacks, then i don't think you should drive the CC2520 radio with a CC2530.

    Dual PAN requires dual network base information and you would basically have to time multiplex the stack usage between the two PANs.

    While the CC2530 is capable of driving a transceiver like CC2520 (you could in theory use port 0 to handle interrupts from CC2520), I don't think you will be able to effectively host a dual PAN system on the CC2530.

    How about using for this purpose two CC2530? It would be a much cleaner solution and the stack could really run independently.

    Thanks,

    Thanks for your response.

    The scenario is, I have to support 1000s of sensor devices under single PAN Id spread over 100s of meters, which can randomly transmit their data. It will form a tree topology. So, I want at router 1 transceiver to be continuously ON on a particular channel to receive the sensor data, packetize it and then transmit it to next level router on another channel.

    Since the sensor devices are in range of 2000 - 3000, which can transmit data anytime and we shall not loose it, we shall have one transceiver continuous ON. If I uses 2 CC2530 then how shall I send the collected sensor data to other CC2530 to transmit it to next level router?

    Looking forward to your suggestion.

    Thanks and regards,

    Praveen, 

    What software are you planning to use? To me, I think if you have multiple networks running it is going to be much easier having 2 CC2530, this gives you two processors that you can then connect using a high level UART type link.

    Hi,

    Thanks for the response.

    I have developed my own version of protocol stack based on my IP. I shall be modifying the same to support multiple transceivers.

    If it is based on 2 CC2530, then will we have to program each CC2530 separately? Will it be possible to debug?

    Thanks and regards,

    Praveen
