Hi all,
I'm working on a Nordic-based system involving multiple nRF52-series chips exchanging high-rate sensor data over both radio and SPI links. The setup involves two...

Howdy!
I am attempting to develop a system using an nRF52840 and an ADS131M04EVM (ADC). Our application requires us to collect data at a high sampling rate (>= 16k SPS...
I have a nrf9160 DK but when upload SLM application to it i can not send AT commands to it over it's usb port but in asset tracker application it works i want to modify SLM...
Hello,
I know this question is more related to Zephyr than Nordic, but I wanted to try asking here.
I’m using the SMP service to send files to my device on a LittleFS...
Hello,
I've connected the nRF8001 module and a light sensor to a microcontroller.
Actually I can read data only when I send a string from my smartphone but I want to...
I'm able to program the Soft Device (s110_nrf51822_7.1.0_softdevice.hex) from nRFGo studio and the compare is fine, but when I go to Keil uVision 5, I can build ble_app_beacon...
I use S130 on two nrf51822/PCA10001 boards. Each nRF scans and advertises simultaneously.
Scan parameters are:
scan_param.active = 0;
scan_param.selective = 0;
scan_param...
Is there a port of lib_aci for 16-bit processors? The structs in lib_aci written for nRF8200 are byte misaligned using a 16-bit processor. Seems to be almost a complete rewrite...
Hello,
I try to generate 4 PWM signals on an nRF51 DK board, but I have two troubles :
in the "Simple PWM", during nrf_pwm_set_value() function the TIMER is stopped...
Hi,
I recently ordered a usb dongle. It has PCA10031 board. The chip shows "N51422 QF ACAB" printed on it.
What SDK should I use? 6.1.0?
What board file should...
Hi!
I am using nRF51 SDK v6.10. I try to analysis the "spi_master_example". Source codes is
working well. But I couldn't understand how the "spi_master_send_recv_irq(...
I have an android application, which one can set and unset the LEDs of my nRF51422 EK. But sometimes when I click to fast the command will not be send. So I would like to...
Hello,
I want to know if it is possible to configure a button to act with different Detection delay.
In other words I want to have a single button to be able to trigger...
Do we have KiCad version of nRF51822 QFN48 reference design? We looking at open source toolkits, including Eclipse, so KiCad comes into picture.
Thank you in advance!
The test code:
int main(void)
{
sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_RC_250_PPM_250MS_CALIBRATION, softdevice_assertion_handle);
temp_init();
unsigned int aaa...
I have a follow-up to this question: devzone.nordicsemi.com/.../
We are interested in dynamically changing the supply voltage because our space-constrained design requires...
Hi,
For my custom PCB, I am using the PCA10004 as reference in order to determine if the maximum possible range has been achieved. However, I am seeing only about 20 feet...
Hello I'v just ordered a NRF51-DK kit.
I'm looking at the different tool chain. In my application speed is critical 16Mhz is actually bearly enough, so my question is:...
I have a USB dongle with an nRF24LU1p that has a few SPI pins but is missing the RESET pin. I would like to be able to program it via SPI but the SPI programming protocol...
