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...

Hello:
I used analog IIC write MPU6050. Again after power download programs, mpu6050 can run up there ACK response. But the debug will not run. Simulation IIC because no...
Hello!
How can I communicate with my nRF24L01+ and nRF51822 at the same time. I can set up same channel, CRC-mode and I don't use ESB. But what about address? How do I set...
I am using S110 7.1.0 which I know has the ability to unblock the CPU during Radio Event. However I would like to do the opposite and increase the time between a Radio event...
Any news on the new specification for S130?
I am trying to find out the concurrent power profile. It the power management section it said that it has not be characterized...
Well, I've ordered my preview nRF52-DK and might get it by the weekend. I have not been able to find the schematics and design files on the main Nordic site, or the new infocenter...
This project is a HRS example from latest SDK, without any modification. I use nrf51 DK board. WHen I debug, I get hardfault after some type. Try to run the code under debugger...
Hi,
we used NRF_UARTE_Type POWER for the "peripheral power control" of the UART interface on nrf51 - works fine.
After trying to port the nrf51 to nrf52 I found out...
The question is: how to completely turn off PWM in SoftDevice?
I am using the libraries nrf_pwm.h and nrf_pwm.c in this repo for PWM with SoftDevice. Everything seems to...
Hi,
when trying to update the firmware with current nRF Master Control Panel (version 1.10), the update finishes successfully, but the firmware does not run.
The problem...
I've tried a trivial example (blinky-like, compiled by gcc using proper startup and ld scripts) on nRF52 devkit, but I always only get hard fault.
Debugging through the reset...
The nRF24L01 dataseet V2 (the most recent I think?) states (p.23) that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz . The channel steps are stated as...
I am completely confused by the nRF51 UART. I'm trying to port code originally written for an STM32 (another cortex chip). There, I define an interrupt, enable the RXRDY or...
Hi,
I need to have two different interrupt handler for one pin?
For LOTOHI one handler and for HITOLO another handler, how to do that?
Here is what i did until now...
Hello Nordic and fellow developers
While implementing bonding into an application based on S130 I found it necessary to test on the role of a given connection. Different...
