Flash memory data transfer using BLE uart

[Siva]

Hi,

In our project we need to store data onto the internal flash memory.

The data that's stored will be transferred and modified via "BLE uart service". When I tried, BLE gets disconnected for unknown reason.

Any advice on this will be very helpful.

There is a Flash Write example in the SDK which shows simple write to flash using low-level programming. You can also use the flash storage (fstorage) or flash data storage (FDS) modules, which provide higher level functions for reading and writing flash. Check out the library desbriptions and API reference:

• Flash Storage library
• Flash Storage API
• Flash Data Storage Library
• Flash Data Storage API

You can find an example of FDS for nRF52 here. Unfortunately this is written for SDK 11, but you should be able to easily port it to SDK 12.
