How to setup Bluno Nano to iPhone 4S

Good day!

I bought a bluno nano last month.

I thought the set up was easy but it turns out the instructions are pretty vague. Could anyone help me?
I'm using an iPhone 4S with iOS 8.1.2

On the link above, click 5.Bluno Basic Demo
The step by step instruction says to upload the code to the bluno using 'Arduino UNO' as the board. It uploaded successfully. Next, I need to compile the source code to my apple device. This is the part that frustrates me; since I can't paste anything on my internal storage, I can't do anything else on the bluno.

Please help me set it up  :smiley-sad-blue: 

 

Code: Select allvoid setup() {     Serial.begin(115200);               //initial the Serial } void loop() {     if(Serial.available())     {         Serial.write(Serial.read());    //send what has been received     } }
