    Hi I'm trying to implement AES encryption by software on a CC1101. As you know, there's not an AES co-processor in this chip, so I'm trying do this by software. In one of the overview presentations about SimpliciTI (see here: http://www.csupomona.edu/~rfsmith/ECE499%20MSP430/SimpliciTI...

    Ok. I can understand this. It's a bit different from my initial idea, but I can understand it. Thanks you a lot of. But, to continue learning, I'm going to complicate it a bit. We're going to suposse that we have the next two star networks: Star Network 1: Join Token = A -AP1 -ED1 -ED2...

    Yeah!!! It would be easier, but not funnier!!! Seriously: It wouldn't be very difficult, and at least it would be very instructive for me. I'm not asking for very complicated concepts or utilities. Only set the join and link token on-the-fly, and init and restart the interface radio, although...

    Hi I've learned how change the join token and the address on-the-fly (but before SMPL_init) of the APs and EDs. My question now: what happens if I change the join token after SMPL_init? This is when I have already several devices connected. What happens? If I have understood your explanation, the...

    Thanks you a lot of. But don't worry: finally monday afternoon I was able to run without problems the example "AP as data hub". The solution was simply execute "clean" when changing from ED to AP. A very silly problem. I'm trying to know how SimpliciTI runs. And it's...

  • Forum Post: Re: Help please! Basic questions about LINK TOKEN

    ardoster
    Well, my idea was that if I change the LINK token in my AP, this wouldn't accept/receive more messages from all ED, except from one specific ED using the new LINK token. In other words: I want receive messages only from one specific ED, and don't accept messages from the others. I thought that...

  • Forum Post: Re: Help please! Basic questions about LINK TOKEN

    ardoster
    Ups!!!! I didn't know that. I thought the first communication was with the JOIN token, and after, communications were realised using the LINK token. So, do you have any idea to avoid receive message from certains ED??? Ideally when using Auto_ack mode. Or I must modify SimpliciTI to implement this...
