ios - Red Bear Lab BLE Shield isn't connecting to my iPhone -

i've purchased this: http://redbearlab.com/bleshield/

i've connected arduino , i'm trying run first test program tell me run ble controller sketch. i've connected , resolved original compile errors got, , upload. when upload it, iphone unresponsive shield. i'm trying figure out if problem in code or if it's problem shield itself. if it's code, how fix code? i'm relatively new arduino , new making work bluetooth. here's entire sketch guide told me download github.

any , appreciated.

i've been working these quite bit in last 8 months, i'll can help. don't have reputation comment , ask clarification on specific things, i'm gonna try cover can.

let's first lay out few things:

• because sketch uploaded i'm assuming have added of necessary libraries arduino. if haven't, don't know why uploading, sure that.

• the problem won't arduino code. i ran code provided, sketch provided rbl (red bear lab) on computer. i able connect iphone using both sketches.

i'm going lay out think potentially source of problem:

• make sure of header pins (you should have bunch of headers sticking out of board in rows of 3 next digital pins) connected correctly, rbl shows in instructions. if want me provide picture of mine can that.

• make sure white power light on on shield. if isn't, power isn't getting shield itself.

• be sure have bluetooth enabled on phone.

• you didn't mention downloaded app. sure (it called "ble controller" redbear), cannot connect iphone without app (apple's bluetooth menu not show ble shield).

• if have downloaded app, sure have selected correct setting choices using button on top left of screen (3 lines on top of each other). sketch provided, should select ble controller.

if have tried , nothing else working, try 1 of other sketches provided rbl, such simplechat. uses serial monitor on arduino communicate , forth iphone. if doesn't work, upload picture of specific shield (the top of it) can take @ it. best of luck.
