Bluetooth master tutorial/resources?

I'm not sure where to put this, so if this is the wrong place, I apologize.

I'm working on a project with bluetooth, and I am having a devil of a time finding a good source of information for it. I can communicate fine in slave mode, and AT command mode (thanks to some help from here), but master mode gets a bit confusing.

Anyone know of a good resource for information on using a module in master mode? I'm using an HC-05, but anything would be helpful.

I wrote the seller and they sent me a manual, but it is not in English. It's not a whole lot of help.

Ther must be a bluetooth website with forums some where!


Probably Mark, but since this is an arduino project with just 1 bluetooth task (device detection), I thought it would be ok to ask here. If not, I apologize. I'm sure you will be seeing many more non bluetooth questions from me soon. :)

pito, excellent. The mcu-turkey link was exactly what I was looking for. It's a much better translation than the document I received that appears to be in Chinese.

For anyone that may be interested, or searching this later. The full HC-05 command set can be found here:

I probably would have never found that without the info in the mcu link that pointed to HC-0305.
