I’m experimenting with an alternative library approach to implement Bluetooth LE device firmware (named Bluetoe). This already works, but is still highly experimental. I wrote a blog article to introduce the library by showing how easy it is, to build a GATT server, that can be used to switch an LED (a more complex examples that implements the Cycling Speed and Cadence service is available on Github). As the first and only target hardware for the library is the nrf51422, I thought you might find this en...

Hi all,I'm working on a blog explaining from scratch how to develop a BLE application with nRF518122 chip. Step by step, I explain the different aspects of the embedded system development in a GCC environment (toolchain, makefiles, linkerscript and C code). I also explain how Bluetooth Low Energy is working and how to implement it thanks to Nordic Semiconductor's SDK. So far if you follow all the tutorials you should be able to control remotely RGB LED directly through your smartphone. I'm gonna try to wr...

IntroductionThis post is an introductory tutorial to SEGGER Embedded Studio. If you haven't already please skim through this post https://devzone.nordicsemi.com/blogs/825/segger-embedded-studio-cross-platform-ide-w-no-cod/ but don't follow along with it. This is the new and improved tutorial using the nRF device pack and assumes no prior knowledge on Embedded Studio.After following this tutorial you will be able to build, debug and run a BLE project on nRF5x devices! You will also be able to load a softde...

In this [post](https://devzone.nordicsemi.com/tutorials/11/nrf51-current-consumption-guide/), I can register a new case with some required parameters to have the current estimation, but I don' t know how to obtain some of them.I'm using nRF51422 dongle with S110 ble_app_uartConnection interval:From this [post](https://devzone.nordicsemi.com/question/30611/data-rate-measurment/), it syas the master control panel has the default CI of 20ms, so I can just use this value or I need a sniffer to obtain the real...

nRF51822 + SE2576L

Hello everyone. I want to increase the operating range for nRF51822. To do this I added PA SE2576L in design.Unfortunately, I do not have experience in RF develop, so I just used reccomendations from this topic:https://devzone.nordicsemi.com/question/6416/how-can-i-use-pa-to-increase-the-rf-coveragePlease make a quick look at my schematic and say how it look like. Is it ok from your point of view? [nRF51822 + SE2576L.PDF](/attachment/f4a2d2dc4de872103bdd4cbeafa0b0f4) Thank you in advance.Sincerely, Preten...

In the example iOS app and the DFU service in the firmware there is a DFU revision characteristic UUID 0x1534. The Nordic SDK documentation don't mention this characteristic or its properties.Is this characteristic required for firmware updates?...
