Read configuration from bluetooth remote control

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I am currently working on emulating a remote control unit using the raspberry pi 3s onboard bluetooth/wifi chip. I already installed bluez-stack and played around with bluetoothctl/hcitool but could really establish a proper connection

The chips used are:

STB - Broadcom BCM43602KMLG (BT Classic)
RCU - Broadcom BCM20734UA1

Steps I tried: bluetoothctl --> power on --> agent on --> scan on --> scan off --> devices. Unfortunately the STBs BT MAC address is not shown there. Another problem is that the STB is running some kind of ARMv7l Linux distro with proprietary BT implementation and I have not yet been able to find the BT MAC address nor the actual BT stack implementation.

My guess here is that the STB is expecting some special authentication by the RCU.

So my question is if there is the possiblity to read that config/auth-information from the RCU and then spoof it using the rpi3. I think of something close to the process of "porgramming" one of these old IR-remotes which read key map from TVs.


Best regards,


Ilyas Keskin
