Hello forum!

I was reading topics here, googling and I can't find any code to do this.

I developed an android app that sends signals to my arduino nano via bluetooth. Everything works ok, but I want to do some actions in my sketch if the android device connected to arduino has a particular MAC address.

How can I know the MAC address of a device connected via bluetooth to my arduino?

Thank you in advance.

Where is the documentation for this product?

@A_tec, please do not cross-post.

Sorry!

Do you mean bluetooth module? There is no specific documentation for this bluetooth module, I bought it in DX

If there is no documentation then how can we help?

Maybe you can't, perhaps someone have the same device or knows how to get this data.

I think we might be at the stage where anybody who asks you for the documentation isn't going to be of any help to you.

I'm not completely au fait with these devices, and I don't understand what you are trying to do, so I have a question. Why do you want a MAC address?  

I do have a JY-MCU that looks exactly like yours, and it works, but I am not using it the way you want to.  

As I understand it bluetooth devices recognise each other, get paired by the user, and talk. That is their job, and that is the way I use mine. No MAC address.

It appears that the JY-MCU label simply refers to the board with a four or six-pin connector, and the HC-05 module is fixed thereto.  The HC-05 is what you might want to know about, but probably don't. As far as I know, there is no documentation for the JY-MCU, and there is no need for it. All you need to know is written on the back of the board.  

Documentation for the HC-05 is here

and here

and I can't find anything about mac address in either of them. I'm not surprised about this - yet

I want to secure the access because I will use the arduino to open a door, first security is change the bluetooth pair code, the second one is filtrate which android device can open it.

I need to know which device is connected, if I have this in the sketck I don't care if you run my android app and know the bluetooth pair code.

Maybe saving in a var the devices previously scanned with AT+FSAD=<Param>?

Thanks for docs!

I don't know. I'm only into datalogging.
