eZ430 Chronos - Two watches simultaniously?

Other Parts Discussed in Thread: SIMPLICITI

Hi everybody,

is it possible to distinguish two (or more) eZ430 Chronos watches, which a sending at the same time on the same frequency? Is there some kind of serial number, which is transmitted by the watch, which would make it possible to distinguish different watches on the receiving side?

Best Regards,

Stefan

    Hi Stefan,

    each node in the SimpiliciTI network (i.e. a CHRONOS watch) has its own address (THIS_DEVICE_ADDRESS). I don't have a CHRONOS, so I can't tell you the exact location (in which source- or header-file) of the address definition; usually it is done in a configuration file in the IDE.

    Stefan,

    The --THIS_DEVICE_ADDRESS is set in the chronos project under the file "smpl_config.dat".

    By default, all chronos watches have the same address (0x79, 0x56, 0x34, 0x12).
    If you want to use two chronos in the same network, each chronos must have an unique address.

    Other configurations may be required in order to use Simpliciti. I can't help any further without knowing what kind of network you application needs.

    Do you intend to use the Access Point and two Chronos?

    Hi aBUGSworstnightmare, hi Patrick,

    I've found THIS_DEVICE_ADDRESS in the smpl_config.dat file. Thanks. Yes, I want to use the Access Point. I think I'll change one of the device addresses, and I'll test if the Access Point can receive both signals simultaniouly (Or if a modification in the Access Points firmware is necessary.)

    Best Regards,

    Stefan

    Hi Stefan,

    Just the device address is not enough for the communication between two chronos and one AP. The reason for that is that the AP is configured to accept just one connection at a time.

    If you want to change that you have to change the code from the access point and flash it with a CC debugger.

    Best Regards,
    Patrick
