We've developed a custom board based on the nRF51822-QFAA and an MPU-6050 IMU. It runs on a li-pol battery and uses S110.
I've encountered a strange problem when power...
Hi,
I am working on measuring the voltage on a lithium battery (norminal 3.7V) with a voltage divider on nRF52832. The voltage divider combines a 510K and 360K resistor...
Dear Nordic Engineer,
I need to work on nRF52, my Macbook Air has OSX Yosemite 10.10.5 - I can run "make" or "nrfjprog" only if I copied libjlinkarm.dylib into the same...
We have a custom board using the ISP130301 BLE module (containing a nRF51822, 16MHz xtal, 32kHz xtal). Our apps work fine (gcc, SDK6, S110v7) except for high system on idle...
i don't see where the command queue index, m_op_queue.rp, is initialized.

Hi,
I'm using the nRF5_SDK_12.0.0_12f24da and S132 on nRF52832. I do the multilink based on the ble_app_multilink_central example. When it has connected to the peripheral...
Hi,
I want to use spi list feature without ppi. Is that possible?
Because I have to use the same spi module for OLED, SPI flash and accelerometer with FIFO, spi ppi...
Hi There, PCA10004_Schematic_And_PCB.pdf
We are working on Nrf51822 chipset and have observed in our case that once we download the code we are able to discover the device...
What I am trying to achieve is single-file executable for nrfutil tool, for performing DFU.
I downloaded sources and built it using pyinstaller. I can succesfully create...
