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...
Hi，
I ran into this error:

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...
Finally we got our prototype boards and proof of concept firmware code done and we are a bit stuck on the average power consumption over time for the entire sensor that is...
I'm able to successfully use peripheral/uart example to read the data from GPS module. I achieved the same by setting baud rate to 4800, and connecting rx and tx of GPS to...
Hi,
Question about FOTA (firmaware upgrade over the air).
I know that nrf52832 has 512 kB of flash, and the ble stack( softdevice ) has 136 kB , and the bootloader has...
Hi,
I put my NRF52 to sleep (POWER OFF mode) and configure it to wake on GPIO port event like so:
This GPIO is set up on a reed switch. Occasionally, the NRF52 will...
Hi
I found a strange issue on nrf52832. And I use nRF5-SDK-v13.1.0 .
When I assignment P0.7->SCL & P0.6->SDA, the twi function not working. But I change the assignment...
Today I read about the new nrf52810 and I want to know about its main differences with the nrf52832.
I see a lower power consumption for the 52810 vs 52832 and no NFC on...
Hi
Currently I try to migrate my software project (with SDK14.2, S132 (5.0.0), arm-gcc toolchain ) from nRF52832 to nRF52810 (with SDK14.2, S112 (5.1.0), arm-gcc toolchain...
Hello everyone, I am a beginner in the use of Nordic Thingy: 52. I would like some help trying to reprogram the Nordic Thingy module. After a programming error of the Thingy...
HI,
I am unable to communicate between a SDK 8.0 based nRF51822 sender and SDK 14 based NRF52832 receiver.
The data rate of the SDK 8.0 sender is 250 KBits/sec, whereas...
Hi,
Can someone help me with question on SPI?
What is the difference between SPIM and SPI? They seem to have different clocks
Also in the SPIM section, the frequency...
Hi there,
I am developing a BLE dongle on nrf51822. There is no external 32.768KHz crystal oscillator on my customized board(only has an external 16MHz oscillator)....
hi,
I need to know how to use "power on reset". From the reference document, I can understand BOR and POFWARN. But the POWER ON RESET, I could not get any idea.
1. POR...
i have project with nRf51822 and uart. i use uart fifo in Uart_app_ble example sdk11. now i need disable or enable Rx, TX.i tried this function :

Hi,
Has anyone successfully used semaphores/mutex implementations of FreeRTOS?
The code I am working on is based on the FreeRTOS HRS SDK example. I am looking to add a...
Trying to compile using the on-line Mbed compiler. I keep getting cannot find "nrf.perhiperals.h", and I cannot locate it either.
Possible someone can point me in the right...
Hello.
I'm using Tielen Marjle STM32 library for nrf24l01+ ( https://stm32f4-discovery.net/2014/06/library-17-nrf24l01-stm32f4xx/ ) which worked great till now, when I...
