Great, I have the same idea on mind, just thought maybe there is an easier solution for this, anyway - thank you!

You can send an entire file through BLE, but you have to divide it up into smaller packets. For example, DFU sends a packet that can be up to almost 128kB large for doing firmware update. You can also look at the ble_app_uart example that takes a string of bytes sent from a terminal program on the computer, divides it into 20 byte packets and sends it over BLE. and of course combine this with the SD Card Example to write the data to the SD card.

Hi Martin,

I have seen that, but there is no information about how to receive file. I mean I'm the newbie, so maybe if there is existing project or someone who will explain how to receive file from smartphone.
