Hi, I wanted to ask a question regarding sending data.
I currently have external memory that will send out serial data (SPI) to the nordic microcontroller. I have saved...
Recently, I try to programme nRF51822 DK communicating with nRF2401e1 DK,unfortunately,which does not success. With setting radio configuration: TXPower,frequency channel...
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...

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 .....
I'm working on designing a very small footprint PCB with the 52832. Not much ground plane (PCB area is 25x30 mm). What would be the general recommendation for a small chip...
Now we use the SDK V11 I2S sample program to collect data of digital microphone. We want to get the frequency of the sound and the dB value size.I don't know how to calculate...
Hi guys,
I want to know if it is possible to get started on developing applications for nRF51822 without using the evaluation kit. I want ot have a couple of breakout boards...
Hi,
I am testing that nRF52832 transfer QVGA still image from image sensor to phone as follows.
nRF52832(nRF52 DK) is connected with image sensor through some...
