Read 10kB from internal flash and send it via NUS UART BLE

[svecoldr]

Can you please provide an example on how to read 10kB from the internal flash using pstorage_load and send it to mobile phone (NRF Toolbox) via NUS UART BLE ble_nus_string_send?

A modification of ble_app_uart example from the SDK to do the task would be awesome.

PS: Similar questions have been asked before such as

devzone.nordicsemi.com/.../

but I could not find any answer that would show the complete solution to this.

Why not start by modifying the example just to send a small string from pstorage, then extend that to be able to send an arbitrarily large amount of data ...

Well, I have tried but so far I have failed. I do not know for example how to synchronize BLE and Flash read. BLE can send only a 6 * 20 bytes then have to wait. In the meantime I should read next data from flash to be ready to send them. I am also afraid that my solution will maybe work but will be far from good. That is why I really hope somebody knowledgeable could spend his/her 5 minutes and provide an example that everybody could benefit from.

As for the first part of the question. Here is an example on how to send large data via BLE:

I will add example with flash as soon as I make it work.
