Thingy external connection

[Sheldon]

In order to connect an external sensor to the available pins, will we need to create our own version of the FW in order to communicate with the sensor? Or are there generic methods to communicate?

As there is basically infinite number of possible interfaces (on both HW and SW level) it's almost impossible to develop magic plug which will be able to communicate with any sensor. So yes, you will need to develop your own FW to work with such sensor.

Call me naive but this approach will never get you security, performance and power consumption wise where I would like to see any production embedded device.
