Hello ! What is the most inexpensive, yet stable robust and relatively fast micro-controller + wireless setup? I have been asking this question to myself for way too long... Now, I'm curious of your experiences in the different flavors available.. In my specific situation talking…

Awesome Find Rogue ! That’s what was frustrating me… SparkFun has had Smirfs for ages but they are always @ $40 to $50 a unit… seemed frustrating when the uC is less than half that price. So now we are looking at : 115K Serial with no Servo contention, Computer->Robot with a BBB…

You have a point voodoo But its not BT so - the computer would need a tranciever too no? However, I bought 4 msp430s So maybe the least expensive robust solution is : $5 msp430 + Rogue’s Cheap BT find $10 = $15 per unit (woo hoo) Seems a very “Swarmable” price

BT all the way ! Thanks for all the information CTC and advice. I have successfully avoided Xbees because of their price and voltage requirements. I am interested in swarming, but all the information will either be directed by the computer or routed from one robot through the c…

Lower still ! And here is SMD BT for $6.60 - although it looks as if default setting would need to be re-programmed if you want 115K So I could print my own interface to plug into a msp 430, and that would be ~ $10 per (uC + BT) !! $40 for a 4 bot swarm (not including servos, w…

Next BT Question It says these modules have password 1234 … which is fine, but what about BT identifiers? Do they all come with unique IDs like ether MACs? or can the id’s be programmed?

you typically can’t you typically can’t reprogram a bluetooth MAC address, but they should be different. on the other hand you can likely change the module name which shows up during a search, but that feature is module dependent.

Different serial lines would be great ! MRL could just create a new serial line for each Bot (if that is the case) Swarm On !

I’ve found the bare I’ve found the bare Bluetooth modules are difficult to solder even with a microscope and surface mount soldering station, I really don’t like the half via pins they use. The four dollar premium for the presoldered breakout board is worth every penny to me.

in windows each bluetooth in windows each bluetooth device with serial port profile will have a unique COM port associated with it. You can discover it by right clicking the bluetooth icon in the windows tray and clicking Show Bluetooth Devices, then right click the bluetooth d…

MAC’s

Everyone gets their own mac address. I will do some tests but I am pretty sure they will just show up as different com ports and thus, eclipse or processing would simply run multiple serial lines. --one for each unit.
