The bluetooth modules that are offered on ebay all seem to have the same hardware, but have different firmware. This page has some notes on the ones that we have.

Bolutek

Currently used in the GPS from Android to Nikon Camera project.

Initially at 9600bps, commands terminated with crlf and recognized by the following response to AT+VERSION:+BOLUTEK Firmware V2.43, Bluetooth V2.0, HCI V2.1, HCI Rev37, LMP V4, LMP SubV37.Default name is Bolutek and default PIN is 1234.

AT commands

Connecting using Ubuntu

Adapted from this askubuntu answer:

  1. use hcitool scan to find the device
  2. pair the device in the bluetooth gui menu
  3. make sure /etc/bluetooth/rfcomm.conf contains the following:
rfcomm0 {
        bind no;
        device <mac address>;
        channel 1;
        comment "Serial Port";
        }
  1. (differing from askubuntu.com) sudo rfcomm bind rfcomm0 <mac address>
