In the first edition of the book, there is no code for Project 3, Negotiating in Bluetooth. The project just describes how to use the blueSMiRF radio. With the BlueSMiRF v.2 radios from Spark Fun, the principles are the same, but the commands are different, because the BlueSMiRF v.2 is based on a different Bluetooth Radio (see this post for more). The full list of AT commands for this radio is online here. What follows is an update to Project 3, Negotiating in Bluetooth”

In the first edition of the book, there is no additional code for Wireless Monski Pong. The project just describes how to set up the project using the blueSMiRF radio. With the BlueSMiRF v.2 radios from Spark Fun, the wiring is the same as it was with the original blueSMiRF. Configuration is virtually the same as well. The only changes are as follows:

The device name for the BlueSMiRF v.2 radio is SparkFun-BT.

These radios don’t use a passcode, so when you search for the device, you want to choose not to use a passkey. For OSX users, this means that after you’ve selected the device type as “Any Device”, you’ll get the device discovery screen. Click the Passkey Options… button and select “Do not use a passkey with this device”. Then select the SparkFun-BT device.

For Windows users, the process should be the same. Unfortunately I don’t have a Windows machine to test with at the moment, I’ll update this post when I have one.

Once you’ve paired with the BlueSMiRF v.2, the instructions in the book will work just as they did with the original BlueSMiRF. The BlueSMiRF v.2 will not send out a CONNECT message when your computer connects to it, however.

The bad news: Spark Fun changed the radio on the BlueSMiRF radios. The SMiRFs I used in the first edition of the book used the BlueRadios radios. The new SMiRFs use the Roving Networks radios.

The good news: Spark Fun also released the BlueSMiRF v.2, which is slightly cheaper, and uses the Philips BGB203 radio. The command set for the BGB203 is nice, and can do many things the BlueRadios devices could do, and more. I’ll be updating the code examples here on this site, so you know how to use the new radios.
