TroubleshootingBluno

uploading code to bluno

I ordered a Bluno a couple of years age and am just now trying to use it.

I am trying to control the Bluno with the Bluetooth for Arduino app on my iphone.

The app is able to find the Bluno and connect.

 

I was able to load the sample code to send from serial monitor to the iphone and it worked.

 

However, when I changed the code and tried to upload again, it gives the error message

 

 

I have tried disconnecting and turning every thing off, but same response.

Any suggestions on what to try next are welcome.

You can give my method a try.
In your iPhone Settings > Bluetooth, find the Bluno and tap "Forget This Device" (or toggle Bluetooth off entirely).

Plug Bluno into USB. Make sure the LINK LED is OFF.

In Arduino IDE, select Tools > Board > Arduino Uno and the correct COM port.

Click Upload.

After the sketch is uploaded, you can re-pair the iPhone and use the app normally.
