Hi,
I want to connect 2 bluetooth devices called "jy-mcu". I found a couple of boards with the same chip:

I always have to pull up PIO3 to HIGH for to set the device as master. Can I do this with AT commands too ?
Which board you suggest ?
Do I need 2 master or 1 master and 1 slave (I think 1 master and 1 slave)?
How can I connect two chips (searching and pairing AT commands ?)
Sorry,
my english is not the best. I'm from Germany.
