Hello everyone,
as indicated by this question https://devzone.nordicsemi.com/f/nordic-q-a/35692/adding-nrf52-dk-to-github-mesh-demo-for-thingys/138327#138327 I am trying...
We have used a logic analyser to verify this.
SPI initialised and talks nicely with an ADXL362 accelerometer part.
We have interrupts configured.
We go into sd_power_system_off...
Hello! I've soldered my first board with nrf52832 chip + PA on it. Everything works well beside the radio. The real distance (less 10m) even worse than on nrf52dk despite...
Just got my nrf52DK and connecting and dropping the HRM demo to it worked like a charm but since then, all attempts to get something else to run failed. Erasing all and reprogramming...
I have a very simple test program to run the radio through the transmit sequence, each task is called from the radio interrupt handler according to each event.
The process...
I'm pretty new with microcontrollers and SPI.
I connected fisically an nrf51822 microcontroller to an external SPI flash memory.
I connected MISO MOSI ports to some random...
I am using SDK 12.0.0.
I am working with low_power_pwm_init() to initialise the pwm and I have passed a handler while initialising. I want to stop the pwm from the handler...

Hi all
Is possible have DFU in the peripheral side to update a Central app program? Is there example doing it?
I have a Peripheral (custom board nRF52 dongle) connected...
Hi
We use the nRF52832 together with other devices in a housing. Some of the other devices may produce quite a lot of heat. Therefore we wanted to use the temperature sensor...
Hi,
i am trying to flash the softdevice bootloader in Sparkfun nRF52832 breakout board using RPI2 + openOCD through SWD. debug port initialize is failed all the time.i...
