c programming Arduino Bluetooth Help

[Amageing]

Hi all,

 

Firstly, I've tried the Arduino forums for help however their account system seems to be a bit broken... (I'm logged in for the account page, I then go to the forum and I'm not logged in, I then log in to find my password is apparently incorrect...)

 

Anyway that's besides the point. Does anyone know how to get the MAC address of a device connected to a HC-05 bluetooth module on an arduino in C?

 

This is so I can get the MAC address of the device and authenticate it in the arduino it's self.

 

Thanks in advance!

If you don't set the name of the device, the MAC-adress will show up if you look for the Bluetooth-device on your computer/phone.

Thanks for your response Claryn,

 

I think I might have failed to explain the issue properly.

 

I meant for the Arduino to read the Phone's MAC Address, not the other way around.

What exactly do you need this for? If it is for authentication, you can simply set a PIN or password on the HC-05 bluetooth module on setup.

Yes, I'm using the MAC address as a type of two factor authentication along with a physical PIN pad attached to the Arduino. Standard uni project.

Hm. From quickly going over the documentation for the HC-05 and checking online, I can't seem to find any ways you can actually retrieve the MAC-adress of the device that connects to your HC-05. It is weird.

@W-L, Shouldn't this be in hobby electronics?

My issue as well!

Sorry I didn't realise that was a sub-forum for that!

 

Feel free to move the post if you're a mod.

No worries, a friendly mod will most likely move it there soon enough.

Are you using any libraries to handle connections etc. with the HC-05? When I did a course at Uni. where we used the HC-05, we used a library from the Institute that made it easier to use the module. We could set UUID of it, have a seperate bluetoothSerialMonitor that we used to send messages between devices etc. 

If you are using a library like that, it might have some way of getting the MAC-adress.

To be honest, I thought I'd try and figure this issue out before attempting to program it.

 

If there are any libraries you could recommend I'd be very grateful!

Done

@Amageing, check out the datasheet for all of the AT commands, you should be able to find how to get the mac address there: http://www.electronicaestudio.com/docs/istd016A.pdf

Brilliant!

 

Yeah that shows me what serial commands I need to send to the HC-05 module!

 

Hopefully I can get it working from here, thanks mate!
