I have been toying with the idea of using Bluetooth tether to run tests on the iRobot Create. The idea is to be able to write code on a laptop and simply connect to the Create through a Bluetooth tether. In that way, the Create could be running around and doing its thing without having a bulky serial link to the chassis. However, this means an extra $90 to the overall cost of what I have already spent. In essence I would have to buy a Bluetooth USB adapter for the laptop and a BAM wireless accessory for the Create. How this works is that the BAM plugs into the 25 pin Din socket on the Create and acts like a serial connection through the Bluetooth USB adapter into the laptop. The software on the laptop just uses this connection as though there were a serial cable connected between the Create and the laptop. I may use this in the future, but for right now I think that I will concentrate on using the USB to serial cable that I bought originally to perform the functions. Once I get the software running on the laptop correctly, then I can offload the same software to the Chumby and place the Chumby on the Create for a run with no tether. In some ways this will be a better test because of the latency with Bluetooth connections. If it turns out to be a pain in the butt, then I will buy the BAM.
