Description: The BlueSMiRF Silver is the latest Bluetooth wireless serial cable replacement from SparkFun Electronics! This version of the popular BlueSMiRF uses the RN-42 module which has a bit less range than the RN-41 module used in the BlueSMiRF Gold. These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target.
The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.
Unit comes without a connector. Please see related male and female pins below.
This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.

Functions at a decent range through a lead lined wall. Very impressive.
I am using this for serial communication with a pc board with a PIC processor, and it works well. I wish Windows 10 worked as well.
Win10 has a hard time connecting to it, and I have to have win10 forget it and pair it again. Each time win10 pairs it uses 2 new com ports. Eventually going beyond Teraterm’s limit (com12). Then I have to trick the Registry so it will go back to assigning ports below com12.
Anyway this modem has worked perfectly.
Using BlueSmirf modules to control a robotic device via a Bluetooth link. The remote uses an Arduino micro and the Bot has an Arduino Mega. Easy to code and works well.
Added the BlueSMiRF Silver with a 6 pin header to my project board and integrated BlueTooth into my project with ease. Have used ~35 so far with no problems. Pairing sometimes takes a couple of tries, but once paired, Android device can connect flawlessly. Might be the Android device, might be the BlueSmiRF. Tried a number of BlueTooth breakouts and this one was the easiest to use and one of the best documented boards out there.
I need a bluetooth module which supports the SPP profile and this device does it perfectly.
Following the instructions at “http://developer.neurosky.com/docs/doku.php?id=mindwave_mobile_and_arduino”, and modifying for use on a mega’s rx1/tx1, I had it reading brainwave data from the MindWave with the first try.
I have an xbee gps air to ground setup with google maps. However, without the net, its useless. The bluetooth made my smartphone very valuable, as I don’t need the net to use google maps anymore. Tracking weather balloons. As long as I have cell service, which is way more available than wifi, I have a map.
And it was well documented. That was key.
