Does anyone have good recommendations for a bluetooth chip to be used
in a circuit. We are building a series of Autonomous Earth Movers and
would like to do coordination via bluetooth. Are there any chips are
there relatively easy to integrate(ie, not connected by USB), and
preferably connect to the handyboard circuit from gleason research.
if you can mount a tower over the worksite you may be able to put a high
speed ir reciever on each thing and control em over tcp/ip. maybe get
someone with a license to use a low population radio band and do wireless
that way, there's some hobbyest channels that require a license, i think
75hz for one.
Well, in fact there are 3 classes of bluetooth transceivers defined in the
standard. The most
common has a transmitter of about 1mW, but nowadays you can also find cheap
transceivers with 100mW transmitters that should have a > 100m free field
In the long run, the communications transmitted are more important than
the communications. These are going to be model sized(using modified
tonka trucks). And will at most, operate over a range of about 100
yards(at most, more likely is 10 yards). Also, they do not require
continuous transmission, but rather can transmit information when
within range of each other. The information is mostly used to
synchronize, not control. The control will be done onboard the
individual vehicles. For this reason, we have viewed bluetooth as being
sufficient. The problem we are having now is finding an easy(and
preferably semi-cheap) way of integrating bluetooth into these devices.
The chips I've seen so far have had development environments costing
1000+. Wishing to concentrate on developing the autonomy of these
devices, we'd like to minimize the amount of time implementing the
mechanics of the communication, and would rather concentrate on the
data to be communicated, and how to handle when to transmit.
