Incorporating TWI into Template example

[Sensors]

I have some custom hardware (nRF51822) with a couple sensors on it and would like to have the data sent via BLE to a smartphone. This may be timer based on triggered by an interrupt from the sensor itself.

I've opened up a new copy of the template example, thinking this would be a good starting point to slowly tackle the issues. However, I'm not totally sure how I would even begin to go about dealing with integrating I2C communication into it.

Could anyone give me a brief summary of what approach I might take to achieve this?

The TWI code interfacing with the sensor and the BLE code should be fairly independent. The Template Application is a BLE peripheral template and may not be the best place to start for the TWI/sensor part.

In order to keep things as simple as possible to begin with I would consider starting off with the TWI Sensor Example (and possibly the TWI Transaction Manager Example) and get the TWI sensor related code working on it's own.

When you have the sensor related stuff working, or at least an understanding of it and also a understanding of the BLE part, it should not require much effort to move this code into e.g. the Template Application, as it should be mostly independent.

Then you should probably still look at the examples from the SDK and merge what you need into the Template application. (Unfortunately there are no examples in the SDK that use both TWI and BLE).
