ATTINY85 and HC 06 bluetooth module

Hello guys,

I would like to connect my ATTINY85 to hc 06 bletooth module. But I am a newbie and I am not quite sure, which pin I should connect to RX and which one to TX pin?

Thank you,
Kevin

Any serial on the tiny 85 will be software serial of some sort. That means you can't receive while transmitting and vice versa. When you create the software serial instance, you tell it what pins to use.

If using my core (for parts that don't have hardware serial) there is a software serial named Serial, built-in. It uses Ain0 and Ain1 (the analog comparator pins), and uses the analog comparator interrupt, so it doesn't fight with other uses of the pcint interrupt. I don't think most cores do that though
