Issues with wiiuse events
January 30, 2011 04:57PM
I just started using the wiiuse library. The program is successfully able to find and connect the remote but no matter what I do, it generates only the WIIUSE_NONE event. When I press a button or tilt the remote, I expect WIIUSE_EVENT to be emitted but this doesn't happen. What could be the problem ?

Also, I tried IR Tracking and set the Virtual Screen Resolution to 560x420, but I get very large values for the x and y members of the dot[] array. Why does that happen?
Here's the code:
#include < stdio.h >
#include < stdlib.h >
#include "unistd.h"
#include "wiiuse.h"


void handle_event(struct wiimote_t* rm) {
        printf("\n - IR Activated - \n");
        wiiuse_set_ir(rm, 1);
        printf("\n - IR Deactivated - \n");
        wiiuse_set_ir(rm, 0);

        for(int i=0; i<4; i++){
            if( rm->ir.dot.visible){
                printf("Source:%d (%u, %u)\n",i, rm->ir.dot.x, rm->ir.dot.y);

void handle_disconnect(struct wiimote_t* rm){
    printf("\n - DISCONNECTED %d - \n", rm->unid);

int main(){
    wiimote** remotes = wiiuse_init(NUMBER_OF_REMOTES);

    printf("Found %d remotes\n", wiiuse_find(remotes, NUMBER_OF_REMOTES, 3));
    int conn  = wiiuse_connect(remotes, NUMBER_OF_REMOTES);
        printf("Failed to connect remotes\n");
        return 0;
    printf("Connected %d remotes\n", conn);
    wiiuse_rumble(remotes[0], 1);
    wiiuse_rumble(remotes[0], 0);

        int detected=0;
        if(detected = wiiuse_poll(remotes, NUMBER_OF_REMOTES)){
            for(int i=0; i < detected; i++){
                    case WIIUSE_EVENT:                  printf("\n - WIIUSE _ EVENT - \n");
                    case WIIUSE_DISCONNECT:
                    case WIIUSE_UNEXPECTED_DISCONNECT:  handle_disconnect(remotes);

                    case WIIUSE_NONE:                   printf("\n - WIIUSE_NONE - \n");
                    default:                            printf("\n - UNHANDLED EVENT - \n");

    wiiuse_cleanup(remotes, NUMBER_OF_REMOTES);
    return 0;

PS: I'm using Linux (ubuntu 10.10).

I think I know what's missing, after taking a quick look at your code. But you expected an answer within 2 hours. So I'll let you wait a bit longer.

I suppose you can answer me now. I've waited for a day here and have been stuck on these for 2 days. I had tried everything I could before posting in the forum.

At first I was thinking you didn't set the report mode, but you are. After pressing a button.

Do you know for sure the wiimote you have really works with libwiiuse? 3th party wiimotes have lots of problems with libwiiuse. And make sure you use the latest version with libwiiuse, and try a 'test tool' first.

I tried this tool:
To see if my wiimote was working correctly with libwiiuse. And at first it didn't because my bluetooth stack was rubish and outdated.

My wiimote is from Nintendo itself.
I am having problems installing Netbeans. I tried installing in twice. Both the times, it came up with some strange problem and I had to install ubuntu again.

Is there anything else I can try?

PS: The remote works fine with the wmgui tool and the demo application that came with wiiuse.

I have been able to get the job done using the cwiid library.
