Managed to get the nRF UART app and the tinyduino to talk to one another. Does anyone happen to have an empty iOS app which only does the bluetooth connection/data transmission?

I'm looking to build a quick smartwatch example.

Now I wanted to make or adapt some icons to display on the screen. I was looking at the flappybirds example and I'm curious how the developers have adapted the flappy bird icon in this example. Have you simply hand coded the icon into a char array?

Or is there some external application which can export images in the byte format expected by the screen?

Cheers
