Transmit file from smartphone to nrf52832

[Anar]

Hello.

I am able to send simple text using nRF Connect app to the nrf52832 and write received data to the SD card.

So I want to send file (mp3, txt, jpg etc) and write this file to the SD card, however when I do scan on my smartphone I can't find my BLE. Is it possible or I need to write addition code for this?

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.

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