Hi

We don't provide any examples specific to this unfortunately, but it should be possible to modify one of the existing examples to send a generic file over BLE: 

In general the best example to use as a starting point for app development is the Android-nRF-Blinky example. 

This is using a proprietary service, which means you can adopt the service to fit your own requirements (just make sure to change the service UUID if you ever plan to go to production). 

The Android BLE library has a split function that allows you to send a large packet in one go, and the library will do the job of splitting it into smaller chunks that the underlying BLE link layer can handle. This should make it easier to send files of varying sizes from the phone to the nRF52 device.

Best regards
