No, sorry, I don't know about any example project/code to share. Maybe you will get lucky with searching on github/google or someone else on this forum. In the worst case it doesn't seem to be very hard to implement...

Not much changes needed, simply define some protocol (message header?) on top of serial data pushed over Nordic BLE UART GATT Service (Characteristic) and encapsulate your file (or whatever else) to it. Bigger questions would be: how would TXT file get to embedded controller like nRF5x? And what it will do with it once received?;)
