Did you ever have issues with a bluno nano losing 1 of the 2 services it comes with and then not being able to connect to it again via ble?

Are you able to upload some of the examples that come with Arduino? E.g. Blink, etc. I think try to get that working first to confirm the Arduino drivers, etc are all set up correctly. After that, try uploading the MobBob program. All the best!

Hi,
I need your advice on how to upload the mobbob program.
My bluno is V1.0
When I connect the bluno to my laptop, it could be detected and occupied the com 6 as Arduino Uno. there is a red LED on and stable, and the other 2 LEDs keep blinking and changing colour between red and yellow.
The problem is the resets process always fail ,and the mobbob program cannot be uploaded as well.
What can I do?

Thanks!

Hi Tim,

The dimensions of the battery are:
70mm x 40mm x 23mm

Also, while measuring it… I discovered something I never noticed before! The battery can be charged wireless using a Qi charger. 😀

All the best with the build!

Hi Tim,

That’s great to hear. I’m glad it’s working now! 😀

Hmm. Maybe that need for the prototype is due to an update in the Arduino software. I haven’t compiled it in a while and may not have the latest Arduino on my machine. A while back, there was a change in the Arduino software that meant I had to rearrange the code (or add function prototypes). I’ll have a look in into it too.

Kevin,

Disregard this – I’m new to the Arduino IDE and didn’t realize that the code wasn’t even compiling and uploading (char * -> const char * prototypes necessary to avoid compiler warnings treated as errors). All is good once I ‘properly uploaded’ the code 😉

Kevin,

I just picked up a Bluno beetle and am working on building one of these as well, yet I can’t get connected either. In my case I a) don’t have the beetle connected to anything but power yet b) can see the device via bluetooth scan c) get an endless ‘Connecting to Bluetooth Module…’ with bouncing start when trying to connect (either bluetooth or bluetooth LE) and both a Galaxy S4 as well as a Nexus 6P. I went through the AT setup and can get AT+VERSION=? responses and all.

Any ideas?

Also, can you post the dimensions of the battery pack you use? The one you recommend appears to be no longer available and I wouldn’t mind finding something that would fit in the holder you designed.

Hi Kevin,

Thanks! I believe I built all 3 mobbobs correctly. It might be some bluetooth LE issue as it seems to be connectivity related.

I appreciate your effort and hopefully, there’s a tweak that will fix it.

Hi Dana,

Thanks for the update! I’m still continuing with my tests and investigation.

Hi Kevin,

I just finished my 3rd build. All 3 have 1.96 firmware. I did the default resetting before loading the program code though instead of the other way around. It works better with my android 4 but doesn’t work with my boss’s android 5. Hmmm.
