 When we built our Bluey nRF52 BLE dev board, we were looking for an inexpensive option for our users to upload code to bluey and debug it using ARM GDB. We then came across the blackmagic probe (BMP) project - an Open Source debugging tool for embedded microprocessors. It greatly simplifies the debugging and code uploading process using just ARM GDB - no need to run a GDB server or use an additional complex tool like openocd. Although the BMP hardware is excellent, it's bit beyond the budget of our ...

The day after the Bluetooth SIG announced the 1.0 spec of the Bluetooth mesh we are happy to announce the nRF5 SDK for Mesh for our nRF51 and nRF52 Series SoCs. This first (v0.9.1) release is packed with new features and concepts for Bluetooth. What is Bluetooth mesh? The mesh capability is a significant update and enables a radical new approach to making Bluetooth applications. With this update to Bluetooth, there are significant changes and many new concepts to learn for developers and product ma...

We’ve all seen the hype on 2x Speed, 4x Range, and 8x Advertising data increase capabilities in Bluetooth 5.But what does this all mean?? How does it achieve all these improvements? Is it really possible to achieve all these simultaneously?? What about power consumption?In this blog post (first in a series of posts on Bluetooth 5), I go through each of the new Bluetooth 5 features. Other topics covered include: Overview of Bluetooth 5 and its major improvements How Bluetooth 5 achieves higher speed a...

Hi, I'm looking for a BLE device to work with an arduino and to speak with a smartphone.The point is that the connection should be made by the user via the smartphone. This connection would be rare and short (around 5 seconds to transmitt data and every 5 hours or so)Meanwhile, I would like low consumption (sleep mode ? Then the problem is how to wake him up, since it has to be woken up by the smartphone...) So my questions : In sleep mode, can we pair with the smartphone and wake him up. I think no...Wha...

Hi,I tried to flash the [mbed FOTA bootloader](https://developer.mbed.org/platforms/Nordic-nRF51822-FOTA/) on my nRF51 DK. I copied the bin file to the bootloader device. It said the storage on the device is to small. Now it won't show up as a USB device and the **LED5 is not lighting up** anymore. I tried bootloader and normal mode on two different machines with Linux and Windows.I tried to run ```nrfjprog --recover```, but it says ```ERROR: There is no debugger connected to the PC```.JLinkExe says ```Co...

float f = 1.234;NRF_LOG_INFO("My float number" NRF_LOG_FLOAT_MARKER "\r\n", NRF_LOG_FLOAT(f)));How to simplify this way to show float number by uart in sdk13.1.In sdk 10.0.0 ,i use app_trace_log to debug.And now ,it's a big trobule to transplant my code to sdk13.1,because i have a lot of app_trace_log in use to debug float number....
