Hey Nick & Tim and any other brain users that can chime in on this!
So I've been researching a car pc for quite some time now and have been researching & reading on embedded elec. etc and FB is definitely what I'm needing for a lot of my desired goals.
The most important goal and the first I wish to tackle though is a passive entry system.
Essentially it looks like I'll need an eyeR & FB to do this as the FB needs the computer to operate correct?
So, the main two questions I have are:
1. How would I integrate a bluetooth transmitter and receiver with the FB?
If essentially I'm wanting to have a transmitter in my pocket as the "key" and when I let's say get within 10 ft (which from my understanding bluetooth transmits different voltages from different distances so if 10ft = 3v) then it would trigger an event to unlock the doors. And then consequently if voltage < 3v it would lock the doors.
2. The second question is doing a certain action based on the length a button is pressed. I'll try and make this as easy to read as possible
1 Button
4 Possible Actions
-Action A
-Action B
-Action C
-Off (Revert to no power and no action)
If button press < 5000ms Then
If Action = Off then
Action A = True
Else
If Action = A Then
Action B = True
Else
Action Off = True
End If
Else
If Action = C Then
Action Off = True
Else
Action = C
End If
End If
How could I do this? Or can I do this? The vehicle would there again be off for some of these actions so would eyeR be needed for this?
Thank all of you in advance for any help/support! I'm so excited about this project and all there is to learn!

Correct, the FB as we provide needs a PC to operate. We dont use/develop the eyeR, but from what I can tell it can operate without a PC especially the IR part as far as I know.Originally Posted by w00tw00t111
It is not that simple at all. Bluetooth is a digital communication protocol that requires lots of handshakes. For this to work, you will need a seperate programmable microprocessor to handle the bluetooth side. It will need to monitor an open bluetooth receiver, wait for when a module is in range, start the handshake and security exchange, and then wait to receive data such as "unlock". Bluetooth is not simply a distance/voltage at all.
You would need to use a lot of logic blocks in MDX to do that, but that means the computer needs to be on for the logic to work.2. The second question is doing a certain action based on the length a button is pressed. I'll try and make this as easy to read as possible

I dont know how the eyeR is programmed, so I dont know if that is possible.

As you get near the vehicle, there is no way of preventing the doors from unlocking. That's a breach. Then once your inside, you have to disable the transmitter to lock the doors. I'd stick with the "active" transmitter/receiver to control entry.
I looked at the wireless and I think one had 4 channels. I'm thinking of using one to fire up the PC from a distance and have a couple inputs for the brain. Justs my thoughts.
