Revision as of 00:12, 28 February 2013

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

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.
