Bluetooth Module: The configured bluetooth module, with wiring harness, ready to be installed into the RS Media.The bluetooth module is configured and ready to be installed. What a pain! Once again I lost my TTL-Serial converter, costing me hours of time. I eventually located it while I was searching for suitable capacitors to build a new one.

Once I got everything setup, configuration of the [url=http://www.rfmodules.com.au/sena/promi_esd.htm]Sena Promi-ESD01 Bluetooth Serial Module[/url] was pretty simple, using AT commands similar to a modem. The configuration went something like this.

AT+UARTCONFIG,115200,N,1
AT+BTMODE,3
AT+BTKEY="******"
AT+BTSEC,1,0
AT+BTNAME="RS Media - Bluetooth"
ATS1=1
ATS3=0
ATS4=0
ATS10=0
ATS11=0

Which basically configures it to use 115.2kbps 8,N,1 (same as the RS Media), gives it the name "RS Media - Bluetooth", sets it to accept connections from any other device and sets the password for access (I dont trust my pesky neighbours). It also optimizes the module for throughput and prevents it responding to AT commands in future (so the RS Media can't accidentally send anything that will reconfigure it).

I'd love to install the module into the RS Media right now, but I'm out of time so it will have to wait. Which gives me some time to figure out where I am going install the aerial. Unfortunately its just a little to big to fit under his rear carrying handle, which is where I wanted to put it. The module also has an output that can be used to drive and LED that shows when there is a connection, so this delay also gives me time to think about where I might install an LED, I can't help but think of the NS-5's from iRobot.

You may have also noticed the naked furby in the background, thats for a little hack I'm planning for some time in the next few weeks.
