This tutorial is to help connect a SparkFun BlueSMiRF to the SSC-32 to be used with

We were able to achieve a range of over 50 feet using the 582 ceramic antenna module indoors, line-of-sight. We

11

were unable to test it at a greater distance due to the small size of our office. We can only assume the 158 duck antenna version has a longer

12

range.</td>

We need to create a custom cable. Using a DC-02 data cable as a

37

base, you will need to remove the violet wire's female connector from the black housing on one end. Refer to Figure 1 for an example of how to

38

easily remove a connector from a black housing.</td>

Install the BlueSoleil program, which is included with the KB-018 Bluetooth USB Dongle. Open the program, and plug the dongle into the computer.

The "Welcome to Bluetooth" message shown in Figure 6 should pop up. Type in a device name and select a type. Click "OK" to

continue.</td>

Apply power to the SSC-32, and click on the orange "sun" in the center of the screen to search for Bluetooth devices.

195

Note: When the SparkFun device is first loaded, it will occasionally appear as a device address instead of a

196

name. You must wait until the BlueSoleil program finishes searching for additional Bluetooth devices for the name to appear. Please wait

197

until the name appears before continuing.

In the main terminal screen, type "ver" and then hit "enter" to test connectivity to the SSC-32. You should see "ver"

247

replaced with your firmware's version. Now type "+++" and hit "enter" to activate "Configuration Mode" on the

BlueSMiRF. You should see "OK" on the screen after you enter the "+++".</td>

Type "AT" and hit "enter". You should see "OK" returned on the screen, confirming that communication is still

possible with the BlueSMiRF. If you don't see an "OK", go back through the tutorial and double-check your settings.

259

Now type "ATSW20,472,0,0,1" and hit "enter". This changes the baud rate to 115.2k baud.

260

Note: This command does not return an "OK" on completion.

261

Reminder: Terminal applications do not allow the use of the "Backspace" button! If you make a

262

typo, just hit "enter" and try it again.

Type "ATSI,8". Disregard the rest of the line - it's just leftover from the previous command. You will see a return of "OK"

274

and "01D8,0000,0000" which is the baud rate written in hexadecimal. If this number is different, then you need to repeat Step 12.</td>

In LynxTerm, type "ver" and hit "enter" for the final test. You should see the firmware

For our testing, we did not have to change any timeouts in LynxTerm for reliable communication. However, we did have to change some timeouts in

314

<a href="https://wiki.lynxmotion.com/info/wiki/lynxmotion/view/ses-software/ssc-32-sequencer/" target="_blank">SEQ-01</a>.

315

Click on "Timeouts" and refer to Figure 16 for specific values.

316

It's a good idea to experiment with timeout values. Try to find the smallest values that still allow reliable

communication.</td>
