Hi Sdh,

I would recommend checking out this Getting Started Thread.

For communicating with your PC, I would recommend using a Bluetooth dongle and then you can use nRF Connect for Desktop.

When developing you can also test your application against the nRF Connect application for smartphones.

Regarding your application, you can for example start with the "ble_app_uart" example then add the TWI functionality since you most likely are going to connect to your sensor with I2C/TWI.

You can read out the sensor data with the help of "TWI sensor example" as reference, then send the data over BLE to your computer via the Nordic UART service, which is used in the "ble_app_uart" example.

There are other threads on Devzone of developers doing similar things.

I would recommend checking out this thread since it has a quite similar theme.

//cheers
