Hello,
I'm using the nRF52832 DK to implement the light switch example in mesh SDK. For this example I'm using nrf mesh app as the provisioner and in this app , to add a...
nRF52832 power consumption is high after the SPI peripheral is used (approximately 400uA of extra current consumption). I expect it has something to do with the high speed...
Hi,
I am using the nrf52832 board for my project.
I am using the NUS example as a base for my project.

Why does SPI not work with nrf_delay, from this previous question
devzone.nordicsemi.com/.../
Surely the SPI SCK is a PWM or other timer/interrupt driven clock?
Also...
When i use nrfutil to perform DFU it is passed, but when i send it through STM32 dev kit it Hash validation failed. but however i can see the CRC is correct.
Hello,
I have an AMS AS7261 light sensor that I'm using with my NRF51422 DK to take a light reading, pull it using nrf_drv_twi_tx/rx, and send it over BLE. However, when...
