So as it turns out there is actually a way to properly read the RSSI (signal strenght) from the BT board. This is good news, since I now can actually use a proper signal strength indication to control the keyless entry system, rather than the pseudo-signal-strenght-package-loss-code that I had developed earlier. First tests showed the system works well but needs a little filtering and experimenting to find the right threshold value. Video of the results will be posted soon.
