 Bigger Bigger  Smaller Smaller  Reset Reset

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!

To be sure you would want to research the CSR BC417 chip and the full datasheet for the specific module.

I think you want the SPP firmware which, I hope, would make the module act like a serial modem.  The HCI interface is for controlling the Bluetooth protocol stack from a host computer.  I think it would be harder to use as a serial port.
