BLE

This post is the continued talk about the persistent storage for Nordic nRF52840. In part I we went over using the Flash Data Storage (FDS) library. In this part II, I’ll be discussing another import component, user information configuration registers (UICR).

There are mainly two ways for persistent storage of data in NRF52840: flash and UICR. I’ll be discussing the flash mainly in this part I, and UICR in part II.

Nordic has a good tutorial Bluetooth low energy Advertising, a beginner’s tutorial, and two guides of GAP advertising Part I and Part II. In this post, we will go through some of advertising features in details.

The nRF Serial Port Library is designed as a more sophisticated replacement for the app_uart module, as pointed out at the library’s page, there are many advantages of this module over app_uart:

Nordic provides good examples, but mostly independent from each other. To make a BLE UART service with DFU support, we’ll need to merge the two examples:

Noric provides detailed documentations of Bootloader and DFU modules

The nRF5 series of Bluetooth low energy chip is a very popular platform from Nordic Semiconductor. Currently there are four IDEs with compiler supported by Nordic, however, for Linux users there are only two options available: SEGGER Embedded Studio (SES) and GNU/GCC.
