RE: BT data transfer

Hello
First of all I would recommend you to send raw data over BT, instead of sending a larger file, this will make everything easier for you.
For how to send data I would recommend having a look at the Peripheral UART BLE sample, which uses the Nordic UART Service (NUS). I believe NUS could be a fitting option for sending data in your application.
If you want to learn more about how a BLE service is set up and how it works, here's a tutorial on that.
Best regards,
Einar
