BLE custom service transferring file

[YASH]

Hello there, I am a beginner, i want to know what changes should i make in the already existing example "ble_app_uart" so as to make my nrf51 development kit able to transfer and receive ".txt files" over ble.

Thanks in advance. Regards

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?;)

Ok. Thank you :)
