I want to do a little project, but I'm not sure if it's possible. Since I've never done anything related to bluetooth with arduino, I thought it was better to search these forums to see if there has been something similar done, but I didn't find anything.
I have a Parrot Mki9100, a Bluetooth hands-free system, which has a remote control that pairs with the base system. What I want is to clone that remote control to handle the unit directly through an Arduino. Of course, I have full access to the remote control and the whole system, so I can sniff everything. It would be ok too if the cloning only works with my system.
Right now I don't have any bluetooth board for my Arduino, but before buying anything (maybe the JY-MCU board?) I wanted to know if this could be feasible or if the bluetooth protocol that Parrot uses cannot be cloned.
"RF Remote – While similar in design to the MK RF remote control, the MKi remote pairs with the MKi Blue Box instead ofthe display unit. The MKi RF remote should be paired when power is first applied. After verifying the CR2032 battery is properly inserted in the remote unit, you will need to press and hold the Play/Pause, Answer and Hang-up buttons while the MKi kit is powering up."
Did you ever get anywhere with this? I'd like to control the unit with my steering wheel controls.
Inside is a TI CC1150 Low Power Sub-1 GHz RF Transmitter
It seems to use a SPI interface with a micro controller.
So I've some options to look at:
-Try and decode the wireless transmissions from the remote and replicate.
-Decode/replicate the SPI transmissions to the CC1150 from the micro on the remote.
-Decode/replicate the signal from the receiving (possibly another CC1150?)
-Replace the buttons on the remote with transistors but I'm not sure how the rotary knob works
