I just want to send audio from one point to another and I am not using a smart phone or other BT enabled device. I need one master and one slave. I ended up with two useless slaves.
I am very upset with the abilities of the RN52 especially after the documentation made it sound like a firmware upgrade would give it the MASTER MODE and it never did.
I bought two of these useless RN52s. Waste of money.
I don't understand why all these Bluetooth modules have audio in AND out but not a single one them can be a Master?
