 Bridging Bluetooth LE to different wireless connections, such as cellular, is challenging and there are few out of the box solutions. This is an important piece of the IoT puzzle, creating stationary gateways from low power devices to long range backhauls without requiring smartphones. This tutorial will walk you through setting up such a gateway in a power and data efficient way.The gateway will consist of a bluz Gateway Shield and a Particle Electron. The Electron is a 2G/3G cellular development b...

https://vimeo.com/175834292In the video above, 96 nRF51 devices are completely erased, programmed with a 150kB .hex file, verified, and reset (application reaches main() when the blue LED lights up) in under 25 seconds. (it takes around 6 seconds to do this for one device using nrfjprog, so this is around 20 times faster than writing a script to do this one at a time).nRF5_multi_prog program --family NRF51 -e -f s110-bootloader-devicepage-meshapp-merged.hex -v -rWindows: nRF5-multi-prog.exe since I alread...

PDM stands for pulse density modulation.PDM is a form of modulation used to represent an analog signal with a binary signal. In a PDM signal, specific amplitude values are not encoded into codewords of pulses of different weight as they would be in pulse-code modulation (PCM).Currently, PDM is a very popular and low-cost solution particular into mobile telephones.The detail specification on the nRF52832 can be found at the infocenter.In this example, we would like to show how to use the PDM interfa...
