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...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use

Dear Nordic,
I just started with nrf52840 DK and my custom board. I derived my custom_board.h from nRF5_SDK_15.0.0_a53641a/components/boards/pca10056.h. I need to reroute...

Hello,
I do want to simulate the behaviour of several nrf51 chipsets that communicate over the air. Do you have any suggestion, how to start with this? The best would be...
Hello everyone! I am interested in running some simulations to test a series of algorithms for BLE on nrf52832. Is there any simulator which can easily simulate nrf52832?...
Hi All,
This may not be 100% nRF-related, but:
I have a set of algorithms that are written with Keil uVision 5 for nRF52840 using the CMSIS-DSP library. Now, I would need...
Hi,
recently i made the mesh works but now i need to add OTA.
i've found this tutorial. I'm still trying to generate the keys... every time i try i get some error from...
I can read from the driver using appropriate instructions. But i am not able to write to any of the registers. Please Help. I have attached the functions and datasheet.
