The nrf52832 is quite a competent System on Chip. Even with the long list of errata for the preview release this chip packs a punch.
I've been playing around with this chip for sometime now and have made…
Recently, there are a few queries from Japanese customers on nRF51 production.
Basically the expectations are
- Program the flash as a whole, including bootloader, application and soft device
- Target…
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…
