Hi,
I am using nrf5832 that is running a coap server example.
I have modified it a little so it reads sensor data via i2c and returns the data using the coap callback.
...
Hi,
I would like to receive some suggestion about finding a CHEAP smartwatch / wristband already available that has these minimal features: BLE (with SDK / GATT profiles...
Compiled with Keil4 software compilation and C of the mixed program, the error is:Branch offset 0x00000228 out of range of 16-bit Thumb branch, but offset encodable in 32...
Hi,
I am currently working on a prototype with Silicon Labs Thunderboard sense. I am looking for a replacement product that has NRF BLE module. All I need is a BLE module...
We recently announced that we now support “extended industrial temperature range” (-40 – 105C) on our nRF51822.
The devices supporting -40 - 105C are the QFAA (QFN with 256kB flash and 16kB RAM) and the…
Introduction
Using proprietary protocols can be an effective way of addressing shortcomings in BLE. When communicating between two nRF chips, one can for example use a different packet format or different…
Hello everybody,
I have just published the sourcecode of FruityMesh on GitHub. It is a meshing algorithm that uses standard BLE connections. Plug in as many nodes as you like and they will automatically…
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…
