using 4 Chronos -> 1 access point

Other Parts Discussed in Thread: SIMPLICITI

 

I ve 1 chronos now and planning to get 3 chronos more. my project is collecting data from 4 chronos to 1 access point. I will design an access point circuit, before this design I actually try this configuration with an access point of chronos kit. but I need to reprogram cc1111 in order to use for 4 watchs.

I looked at smpl_config.dat, I think I should modifty it first.

I m wondering that how can I understand "from which watch is the data coming from?"

Is it possible to do this configuration? 4 watch -> 1 access point

should i also buy ccdebugger?

thanks in advance:)

 

 

 

 

 

  • I am trying to do the same but using 2 to 1 and just started to work on it this week.  If I figure it out I will let you know.

  • I purchased a CC debugger and began working today, did you make any improvements?

     

     

  • Hey Gloin,

     

    Actually no improvements yet.  I have had some issues in the office at work so I had to put the chronos aside for now.  I am hoping I can get back to playing with it this week.  I will get back to you as soon as I start.  Sorry for the delay.

  • Hi,

    I  worked with two chronos and I also look at rf2500 sample code for data hub

    I modified smpl_config.dat in cc1111 code and chronos also, I changed the linking code in cc1111, then I manage to see the two chronos datas, but I stucked how can I parse the data by chronos address, I will check rf2500 code again with two end nodes and see how the address parsing can be done.

    At this time, two chronos can link to access point, when I request data by

    0xff, 0x08, 0x07, 0x00, 0x00

    I can see acc data, but in mixed status :)

    I will work and should solve this problem.

    Any advice, idea will be appreciated.

     

     

  • Hi,

    I am trying to do a similar thing with the chronos platform. I would like to connect 2 or more ( yet to be determined ) to one access point. I was wondering if you had any progress made and if you were able to distinguish between the multiple chronos watches

  • yes, actually i found an easy solution

    in main_ed_bm.c file in chronos sports watch software,

    simpliciti_data[0]=0x01; // for chronos 1

    same thing for chronos2 as

    simpliciti_data[0]=0x02;

    and so on for the rest of two.

    then I simply change the code for the access point in order to support more than 1 end device, you may check a nice example from rf2500 kit's software.

     

     

     

  • All,

    You may also want to check out a game that uses 4 Chronos to talk to one access point (not the USB AP however): http://processors.wiki.ti.com/index.php/Electronic_Rock-Em_Sock-Em_Robots. Source code is available for IAR for this project.

  • All,

    Kind of a "stupid?" question. i have been researching reprogramming the cc1111 that comes with the watches. Is the only way to reprogram this unit with the CCdebugger? We have a possible solution for our situation. We are basically using the watches as an electronic tallying system. Our solution being when a button is pressed it initiates simpliciTi and sends its packet then stops its connection opening the access point for another watch input. We are not worried about simultaneous button presses at the moment. Is that solution possible without reprogramming the AP? 

    Thanks in advance

  • Hey Gloin,

     

    I finally am pulling these kits off the shelf.  I am now trying to get caught up and glad to see you have yours working.  How did you get to separate your data in the access point?  I think earlier you said that it was mixed.  I see where to change the address in the simpl_conf.dat file for the address but I see that you have an easier way of doing it but I can not find that main_ed_bm.c file.  I must be overlooking it.  But the main thing is that I have to change the chronos watch with a different  address for each and then make the changes to the access point to support more than one.  I will go get the rf2500 kit and look at the example.  I appreciate any help or advice you have to offer.  

     

    Also for the simpl_conf.dat for the AP I would just to change the -DNUM_CONNECTIONS= to a higher number than 1.  I don't think I can change anything else in the firmware for the AP.

     

    Thanks,
    Steve 

  • Hi Steve,

    you need to look at rf2500 development kit code, in access-point code you will see it is easy to distinguish the data because simplici ti do this for you, in your case to distinguish the data between chronoses, I just wrote 1, 2, 3 so on in first byte of the chronos simpliciti data.

    at the accespoint, I changed the request data procedure from the pc, my accespoint is now sending rs232 data as soon as rf data  comes, it is a right way to keep all data unlost.

    at that time I m away from office for a project, so my own laptop is away, but i m sure you can do it by a careful debugging. Please look at Chronos message bytes meaning on the forum, then check rf2500 code, you will do it.

    good luck,

    Gloin
