Hey guys! I'm new here, so I'm sorry if the thread is in the wrong section or something.

A friend and I are starting on a project that implies interconnecting various components(eg.GPS ) to a cell phone by means of Bluetooth technology. My question is:
Is it recomended to use and IDE or just the stand-alone developement kit??
What advantages on has versus the other, etc. I'd appreciate it if you told me your experiences using whichever one. thanks!
