Bluetooth success


I was able to start bluetooth communication.

Here’s a photo showing a serial communication between the Z2 and a
Windows PC.
The Z2 is running Minicom on port /dev/rfcomm0, the PC is running
Hyperterminal on com9:

Both have local echo enabled, so you can see what you type.

Here’s a picture of the new bluetooth dongle.
I had to make a new one, because I made a mistake and soldered the + wire to 5V instead of 3.3V.
I’ll correct the older posts soon.

Stay tuned.

    I have read in the #zipit irc logs that this nice hack could be followed by an usb radioactivity counter for zipits . I did make some researches 25 years ago on a cheap and simple geiger, and I could ask to specialists. Their answer was to try a photopin diode as the detector, but at these times, this component was rare and over-expensive. Now I can find them for a few €. I thought using my serial modded zipit as a long term counter to make it sensitive, and something like this for the detection part.
    Because I kept a couple of tubes from these times, I will be happy to test and eventually help your own on my ubooted zipit, but your advice on photopin diodes interests me first.

    Hi, what bluetooth module type is it ? what chipset?
    I want to do something similar, except that the remote end of the bluetooth link will be an RN-42 bluetooth serial module. I have had problems getting USB bluetooth dongles to connect with RN-42 for a standard bluetooth serial link. Maybe this would work for me?

      sorry for the late answer.
      Linux should supports pretty much every bluetooth dongle.
      As far as I remember, the one I used has a Cambridge Silicon chipset.
      At least it claims to have one, but it may also be a cheap chinese clone.
