EDTracker Bundle (HCKITS0021, 21B, 21E, 21F, 21G, 21H & 21I)

Thanks again for checking and the additional videos. It does look to me like it's a hardware USB issue. I'll contact you shortly via your email address to sort this out.

Thank you very much!

I have a similar issue,

The board connects to the PC, solid connection is visable on COM port 3 as arduino leonardo however the EDtracker UI does nothing with it. This is the 4th EDtracker that I have set up and the first time the software hasn't responded to it as soon as its plugged in.

The LED on the board is constant red but it isn't talking to the UI.

Ok not sure what was wrong but it worked but the magnetmeter was intermittent for whatever reason.

I tried to redo the soldering in case there was a dodgy connection but now I've fried the arduino board.

I will reorder a new kit.

OK, if you think the pro micro may not be totally dead, and seeing as you're down the road from us, you can always just drop it off and I'll take a look at it myself.

[FatherCool]

No it's dead I think. It was registering before as EDtracker 2 but not working in the UI, then after it wasn't registering as all when plugged in. Think its shot now.

Hey, I just put together an ED Tracker (did not purchase the bundle since I had a pro micro laying around and just needed the MPU9250), but it's not being detected in the EDTracker GUI after flashing the EDTracker sketch. It shows up in device manager on COM4, and also as a game controller, so I'm not sure why the program can't detect it.

I also flashed the MPU9250 sample sketch posted earlier in the thread, and can see that data is being output. I've also tried it on my laptop with the same result.

Any advice would be appreciated

Although it does look to me like you have the correct firmware flashed it may be worth running through he steps in the following post just to make sure its flashed correctly....

...the main thing is just to check you got the firmware from the link in the first step.

Did you see the data change as you rotated the EDTracker?

just to check you got the firmware from the link in the first step.

I copy and pasted the sketch again just to be sure, but got the same result.

I think so, but it's a bit hard to tell. I'm not sure if that's indicative that I messed something up when constructing it.

From your video it's a bit hard to tell but I can see the values changing so this a good sign that the MPU9250 is working and that the Pro Micro is talking to it ok. This does rule out a lot of possibilities.

The reason why I wanted to check this is because although the GUI will connect to the Pro Micro, if the Pro Micro can't talk to the MPU9250, then the GUI will just immediately lock up and appear not work. From your screenshot it kind of looks like that's what's happening - the GUI is connecting to the Pro Micro but not doing anything?

The one difference between the MPU9250 test sketch and the EDTracker sketch is that the test sketch doesn't use the interrupt pin. If this pin has a bad connection then this would cause the EDTracker firmware to lock up so it's worth giving the soldering on that connection a good check. It's the pin labelled 'INT' on the MPU9250, and the pin labelled '7' on the Pro Micro. If you have a test meter it's also worth checking the continuity between these pins.

[Finz]

Thanks for the advice. I checked the continuity on each pin to double check that there were no shorts, but everything looked okay. I'm beginning to think I have a bad MPU9250 unit, or that I inadvertently damaged it somehow. If I get some time in the future, I'll probably give it another shot, or just order a presoldered unit from you guys.
