I’m using the silver sparkfun Bluetooth module (http://www.sparkfun.com/products/10393) to wirelessly connect my smartphone to my arduino mini. But I need a Bluetooth board that’s smaller for where I’m trying to stick the unit. I’ve been looking into less beginner friendly but tiny Bluetooth modules like this one -
Will I be able to Rx/Tx easy out of one of these like with the sparkfun board? The supplier wants to know if I want HCI or SPP firmware, what does that mean? Thank you for any help you can provide!
Any recommendations for a tiny Bluetooth module would be appreciated as well!
