I have been testing the thingy91x and measuring power consumption trying to reduce it to the absolute minimum.
Using a test program that moslty sleeps ( using k_sleep()...
Hello,
I'm working on a project using the nRF52840 and Zephyr, and I'm experiencing an issue when trying to use device power management (PM) with a custom sensor driver...
Hello,
I am new to nRF development. I am going through the nRF Connect SDK Fundamentals course.
I wanted to configure a GPIO on the nRF52833 DK board as an output and...
It seems that I'm getting different results reading QSPI flash from the APP vs MCUBOOT, with the exact same configuration. Writes appear to work fine from either, but MCUBOOT...
I am trying to get the wifi stack to connect to a wifi AP using WAP2 Enterprise (initially just with identity and eap_password, later with full ca_certificate check and client...
I've got some timing-issues with the nPM2100. As I could not locate the relevant information in the datasheet, I'm requesting this here.
My PCB has an nPM2100 with a mechanical...
Hi,
i acheived writting code that reconnects sequentially with multiple reflectors for my 1 initiator. When i am indoor i had good results, but yesterday i tried it with...
Hello,
I made a PWM with the TIMER2 of my nRF51822 (with the SoftDevice) and was working fine, till I read that I should not use the "NRF_PPI" functions and use the "sd_ppi_XXX...
I've got an nRF51822 development kit that I'm trying to get started on. I've gone to Kiel and downloaded uVision 4 (mdk472_a). I install it with all default settings and it...
Hi,
I add UART support using IRQ on the "ant_hrm_tx" example code.
and I'm sending packet of 4 bytes that contains: Delimiter,HeartRate,Battery,Delimiter

Hi, I am trying to test my UART using some simple loopback test, and I have noticed that the service discovery command of BLE will occupy the CPU a quite long time. I am just...
I was unaware that the 'manufacturer data' in the advertising packets is limited to less than a full payload. However, whenever I set it to >6 the program "crashes".

Is there any way to solve...
We have recently moved to a new PCB which puts the nRF8001 on the layout instead of plugging into a nRF2741 development module. The nRF8001 connects to a TI Cortex-M4 Tiva...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
To be more detailed:
One of my ADC pins will be connected to another device that could be providing a voltage of about 3V, but through a 100 kohm resistor. (actually it...
Dear Nordic Developer Zone,
Since I have implemented a timer with interrupt in my application, the debug mode if the Keil IDE stops working when I try to restart the code...
Hello, I'm trying to develop with the nRF51822 Eval kit and GCC and Eclipse. I've been getting some strange behavior and errors lately. I'm not really sure how to describe...
I'm a green hand HW Engineer.
I'm trying to compile, program, and run The Heart rate monitor demo though following the step in nRF51822_DK_User_Guide_v1.0.pdf .

Hi Nordic devzone,
For the nRF51822 device, I would like to know if there is any internal pull-up/pulldown resistor on SWDIO and on SWDCLK (although a 12 K-ohm pulldown...
