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.

Adafruit Feather nRF52 Bluefruit LE - nRF52832. In reality, what we would like is to be able to install a module, with or without the Arduino portions. We are capable of coding the drivers and programs needed, just the entire FW is not needed. Further, it would be best for security and future upgrades if the FW were managed by Nordic, and included the latest Bluetooth Mesh when available. Then, a custom module could be written and added to the device for the FW to execute. And the existing OTA FW updating could be utilized when FW updates were available. At current, the Thingy:52 is really only useful for the existing functionality, which is fine, we would just like to have been able to add functionality. As an extra example, how would we utilize the BLE mesh and have a program monitor the Pressure and send a message to another BLE mesh device (Thingy:52) to flash the LED as a warning?
