The whole point of BLE is to transfer data!

Again, all of the BLE examples in the SDK illustrate transferring data!

If you want some more specific recommendations, then you're going to have to give details of your particular requirements & constraints.

Can you please provide any sample code that actually sends data over BLE??

It's all just data - the fact that it may or may not have been stored in flash is irrelevant.

All of the BLE examples in the SDK illustrate transferring data - it's up to you to think which is most appropriate to your particular requirements.

for "unstructured" data, you might take a look at the Nordic UART Service (NUS).

Although it has "UART" in the name, again: It's all just data - it doesn't matter whether it came from or goes to a physical UART!
