At the moment no. There is a serial port in the module bay, but this has inverted signals, and the HC-06/HC-05 need non-inverted signals. The HC-05 also needs an enable signal. This could be provided by a mod to bring out one of the JTAG signals that may be used as an I/O signal.
However, I am looking into using an Arduino Pro Mini connected to that serial port, accepting the inverted signals, and passing the data on to the bluetooth module. I'm defining a suitable protocol between the radio and the Arduino so the Arduino can also handle the required control signal, together with being able to switch power to the bluetooth module off when it it not in use.
The timescale for completion of this is undefined. I do have most of the Arduino code working, but still need to complete the code in ersky9x.
