Hello ioio not Working

[Frank Li]

I just bought a new ioio-OTG. I can not run hello ioio. I updated the firmware to 0400 and the library I used is also 0400. When the board is connected to the phone, the phone is charging and it is it is debuging. However, the yellow LED just does not response.  I tried different phones and try different versions of libraries. None of them work. Do you guys have any ideas what is the reason?

Thanks

Frank

Disable USB debugging when running your app. IOIO over ADB only works with Android < 4.2.2. Above that you have to use OpenAccessory.

Thanks for the reply. After I disabled the USB debugging and connected the phone to ioio, the hello ioio app pumped out, but the yellow stat LED did not response. I am pretty sure the LED is still functional. Any idea?  Another question is when I use the latest version of libraries, I can not control the switch(Hello ioio), and it is dark. Is that normal?

I recommend that you upgrade both the firmware and IOIOLib to the latest and try again.

I finally get the ioio working on another phone( Samsung s3 android 4.4 2) but it still does not work for Motorola XT 1064 (Android 4.4.4). Any suggestions?

Did you upgrade to the latest?

I used the latest lib, and the firmware vision are shown below. 

Hardware version SPRK0020

Bootloader IOIO0400

Platform version IOIO0030 

I think they are the latest version.

Another strange problem is that my laptop cannot find the ioio unless in the bootload mode.

Your configuration cannot work by definition. You have to maintain (firmware major version) >= (IOIOLib major version)

Upgrade your firmware to v5.x

I am a little bit confused. I used App-IOIO0500.ioioapp to update the firmware, so it should be the latest. However I can not check it, because my laptop can not detect the ioio unless in bootloader mode. 

[Ytai Ben-Tsvi]

Did the upgrade (write) succeed? If so, disable USB debugging and connect the IOIO to your phone. Let it launch the HelloIOIO app. If it does work, connect the phone to your PC, enable USB debugging and examine the app's logcat output. Let me know what the IOIO-related messages are there.

BTW, are you using the precompiled HelloIOIO? If not, please use it before moving forward to your own compiled one, since you might be compiling it wrong.

Thanks a lot!! Now it is working !! I spent one and half day trying to fix this. I guess the upgrade did not succeed last time. Here is another thing I tried to figure it out. I bought a bluetoothadaptor in Best Buy but it does not work with ioio, I guess thats because the version is 4.0. Do you have any recommendations which bluetooth adaptor should I buy?

[Ytai Ben-Tsvi]

Most adapters work. Here's a partial list:

I am just wondering for some adapters, we need to install drivers to make it work. How can I install drivers on ioio?

Thanks

[Ytai Ben-Tsvi]

You cannot (easily). Either they work or they don't. Most do.

Thanks very much for answering my questions patiently!

[Frank Li]

Sorry I am still a little bit confused. If the adapter works, does it mean that all we need to do is to plug it in ioio,  and then we can find and pair it by phone or lapto?

[Ytai Ben-Tsvi]

Yes

Make sure the little trim pot for current limiting on the IOIO is fully clockwise.
