Think I have sensors all around a car. In stead of physically wiring those sensors to a central computer, I want to add a battery to them and have them communicate wirelessly to my main control.
My question is what Wireless Protocol (for the Physical layer) can I pick?
Therefore my requirements are:
- No Pairing should be needed. Sensors and controller come up and can discover all sensors and start getting data.
- There could be multiple cars next to each other and the controller in each car should be hard paired to the sensor in its own system only.
- What steps would be needed during initial installation to pair the sensors and the controller?
Update: As pointed out, items #1 and #2 above seem contradictory. Here is what I can afford. During the initial installation of the system, The factory integrator can scan the sensor 'remote sensor boards' and add them to the controller boards non volatile and select type and location of sensors. So I can afford to do pairing in the beginning. My question is - is Bluetooth a good choice for an application like this? or should i be looking at other protocols too? (I'm a hardware guy so trying to grasp the software stack abilities & requirements)
