How to send data from flash memory to ble?

[Newbie]

Hello, I am using PCA10028 and sdk 12.2.0. Now I have interfaced temperature sensor and I am storing 4000 readings from sample to flash. Once all the 4000 samples are stored I want to send this data to my nrf app using ble. How can I do that?

I am attaching my code here. Please give me suggestions.

Also when I enable memory storage functions my PCA10028 does not advertise.

The example ble_app_hrs-fds-test-github.zip in this answer shows how to use FDS when the softdevice is enabled, I would recommend you to take a look at it. It shows how to write and read data from flash.

For how to transfer the data (fast), I would recommend you to take a look the example ble_app_uart, and specifically how the function ble_nus_string_send() is being called and how its errors are handled.
