Bluetooth Serial Port in OS X
This writeup is based on the guide by Tod, which details how to setup the BlueSMiRF from SFE.
I found that pairing the device to be quite simple, and actually didn’t use his guide at all, but when listing /dev I couldn’t find anything under the BlueRadio name, and this is where his guide came in handy.
You should now have a “BlueRadios” device in your device list. Select it and click “Edit Serial Ports…”.
As you can see, the serial port is already set up for you the way it should be. The only thing to add is to tick “Require pairing for security” since I think the BlueSMiRF modules may require it. [note: test this again]
After setting this up, connecting with the SMiRF wasn’t a problem at all. Points to note,
+++ //to enter command mode
ATMD //to leave command modeChanging the baud rate is as simple as described by Tod. However, the last ‘1′ stores the new baud rate in flash so it can be useful to use ‘0′ instead during testing, i.e.
ATSW20,236,0,0,1 //57600 8N1 (saved in Flash)
ATSW20,236,0,0,0 //same (not saved in Flash)The values for the other baudrates are located in the datasheet, however I’ve verified stable operation upto 230.4k Baud - which is quite impressive. Note, that this testng was conducted with the RP-SMA unit featuring a duck antenna.

Another successful afternoon where I launched Windows XP SP3 inside Parallels Desktop v3.0 for Mac, and connected to my MPLAB ICD2 PIC programmer. Yes, Wow! I managed to test some of the code ...
Decided to layout the PCB and get my bench PSU finished. It features a modular design with PIC output of the voltage measured via the A/D module - why use a PIC? Why not :p It offers flexibili...
Talk about neglecting my blog! Well, wot can I say, I've been busy. As far as interesting goes, I've *also* been working on this, ...where I'm prototyping my GPS clock system. Basically ...
Not sure how I forgot to post this, as I've soldered up a couple of these. I happen to have a fair amount of these RS232/TTL converter circuits on hand. Basically it provides the break out for TX/RX...
Just received my new 'scope today, and managed to do a probe check, adjust its compensation and intend to start testing one of MARV's MCUs shortly. This is the TDS2012B, featuring 100MHz bandwi...
