Hello Nordic community,
I’m working on a project with the nRF52840 DK (PCA10056) using the nRF5 SDK and the S140 SoftDevice. My goal is to:
1. Read two NTC thermistors...
I am trying to write SPI code for the nRF52840 dongle. Since the nRF5 SDK does not directly provide an example for the dongle, I followed the steps defined in this tutorial...
I am trying to build using a custom board and 2.9.1, but am getting these errors:
My dts looks like this:

Hi everyone,
I'm developing a BLE application where I measure throughput between an nRF5340DK acting as peripheral and an nRF52 Dongle as the central (using a Python script...
Hi Nordic Team,
Previously, with the nRF52840, we could use the internal ADC channel to directly measure the supply voltage (VCC) for battery monitoring without external...
Hello, we are developing a BLE application using nRf52833. Because of the waterproof & stainless steel casing requirement with rechargeable battery charging capability, we...
Hello,
I am working with the NRF5340dk, nrf7002ek, and PPKII. I am unable to get the DK to power up with the PPK. I used a knife to break the trace but for some reason...
Every time I want to connect to Nordic ble device from my Phone, it ask for pairing confirmation and then it create bond. That's how it should be.
But if the device is...
I'm using nfr52 with softdevice s132.
I want quickly perform flash write during power loss.
When I realize write using fs_store() I obtain time more than 5 msec.
How can...
Just do
NRF_POWER->SYSTEMOFF = 1;
in main()
and found if it's boot by powerup
the current is 10.4uA~10.5uA
and if a re-flash the hex, the current is 1.4~1.5uA

Hi,
Everyone,
I am using NRF51422 chip for my custom board. with transmission interval set to 2000ms and Tx power to -20 dBm, I transmit 32 Bytes BLE data and Scan and...
I use the softdevice which is s130.The code is from the demo:
static void nus_data_handler(ble_nus_t * p_nus, uint8_t * p_data, uint16_t length)
{
for (uint32_t i =...
Hi,
i'm using SPI to transfer data divided into packets of 24 bit from NRF51 to a DAC. The function that allows to send data is:
spi_master_send_recv(SPI_MASTER_1, data_vector_tx...
I'm having trouble starting my application after power cycling after flashing it with the DFU app.
I started nRFgo Studio. Erased the chip. Programmed the SoftDevice (s130_nrf51_2...
I was just wondering if anyone has any experience with or thoughs about using Zephyr ( www.zephyrproject.org/) or Mynewt ( http://mynewt.apache.org/) that they would like...
Hello all,
i am struggling with the example code of the Enhanced ShockBurst Protocoll in SDK 11. I cannot really see the structure of the code, to which time which event...
Hi all, in the forum I can read about people having issues with wrong CRC in the bootloader, but with SDK11; I have the opposite problem. It is always 0 and is always accepted...
main.c Hi,
I am having an issue with I2C transaction in my program.
There are two sensors(Touch and Temp) connected to the I2C bus. Touch sensor is working well when...

Hi,
I am designing a system that will include an nRF905 transceiver. How accurate should the nRF905 oscillator frequency be for each receiver/transmitter in order to ensure...
Hi all.
Knows anyone someone who use this module with power amplifier ??
Rf module nRF24L01+PA+LNA . I test it .. but still have same distance like module with no PA .....
