To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.
I Modified bootloader project so it compiles with both ble and hci transports. Currently I use button_0 and button_1...
I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Bluetooth LE is not a fast wireless protocol, transfer speeds are usually measured in single-digit to low tens of kilobytes per second. This is generally not an issue unless large amounts of data need…
PCB Design
Abstract:
The SkyenLab Bluetooth module was developed using the nrf51422 QFN48 QFAC reference design as well as help from the Nordic Semiconductor support portal and white papers. A proof…
Our Project
This post is to clarify team SkyenLab’s scope for satisfying the senior design class requirements and Nordic Semiconductor requirements during the first semester (Aug. 2015 - Dec. 2015) of…
This guide will cover the specific areas that must be paid extra attention to when designing a PCB for nRF52832. It is intended as a nRF52832 specific addition to the General PCB design guidelines for…
Since Nordic Semiconductor announced that it has partnered with one of the world’s largest international cellular carriers, iBASIS, to use nRF9160 System-in-Package (SiP) module and to include an iBasis…
The Nordic Thingy:91 is a cellular IoT prototyping platform. It is based on the nRF9160 System-in-Package (SiP). The nRF9160 has an integrated modem that supports both LTE-M and NB-IoT. The factory programmed…
This blog clarifies what are the basic requirements when nRF9160 is used in signalling/RF testing against R&S CMW290/500 test setups.
Setting up:
The RF attenuations can be modified from RF settings->RF…
CoreBluetooth is the native iOS framework to communicate with Bluetooth-enabled Low Power (LE) devices, except iBeacons (which require CoreLocation) and HomeKit devices. It is easy to start with, if one…
