Adding more tags to the system

[anthony211212]

Hello. Has anyone fully solved the issue of adding multiple tags? I've looked into discussions among the question titles here, but I couldn't find a precise and clear solution. Has anyone been able to use this library for multiple anchors and multiple tags for example 4 anchors and 4 tags or more? Or perhaps, does anyone know of a different library suitable for this situation? Your recommendations are highly valuable.

Anthony, My last experience with this lib was 7ish years ago. I couldn't get it to work then. That is why I moved to some other lib and esp32 type modules. I have not been in iot scene for good 3 years now. I'm sorry I can't be of more help.

Hello. I know some modules ESP32 UWB(Ultra Wideband) and ESP32 UWB DW3000(Ultra Wideband). Do you know any library for them to use multiple tags and anchors ?

Bonjour,
Je travail actuellement sur la même problématique. Avez-vous trouvez une solution?
Ou même une façon de limiter le nombres de balises qui ce connectes de façon "propre"?

Hello. Not yet. Do you have any idea?

Update for anyone who encounter this problem
You can find an updated version that fixes this and other problems here: https://github.com/jremington/UWB-Indoor-Localization_Arduino/tree/main/DW1000_library_pizzo00

@pizzo00 Which algorithm did you use to find the tag's position, and what was your error value?

[pizzo00]

The trilateration algorithm is beyond the scope of the library but I personally use the @jremington implementation of this paper with a RMSE of 2m on a distance of 30m from the anchors

@pizzo00 Merci beaucoup pour votre travail. Cependant, je ne parviens pas a utiliser votre bibliothèque, La compilation est OK avec le Biblio d'origine, mais j'ai de nombreuse erreur avec la votre. Devons-nous modifier des éléments dans notre script?

@scal68 Now it is sufficient to call the function DW1000Ranging.init, with the type, the short address, a mac address, a flag for high_power, the transmission mode, and the usual parameters.

My code looks like this:

static constexpr byte MY_MODE[] = {DW1000.TRX_RATE_6800KBPS, DW1000.TX_PULSE_FREQ_16MHZ, DW1000.TX_PREAMBLE_LEN_64};

void setup()
{
    Serial.begin(115200);
    delay(1000);

    uint16_t shortMacAddress = 118;  //"76:00";
    char *wifiMacAddress = "00:00:00:AA:AA:AA"; //I get it from the esp board through WiFi.macAddress();

    // init the configuration
    SPI.begin(SPI_SCK, SPI_MISO, SPI_MOSI);
#if C_TAG
    DW1000Ranging.init(BoardType::TAG, shortMacAddress, wifiMacAddress, true, MY_MODE, PIN_RST, PIN_SS, PIN_IRQ);
#elif C_ANCHOR
    DW1000Ranging.init(BoardType::ANCHOR, shortMacAddress, wifiMacAddress, true, MY_MODE, PIN_RST, PIN_SS, PIN_IRQ);
#endif
}
