Hello, I am trying to use the DPS368XTSA1 sensor with the nRF52833 via SPI. First, I’m attempting to read the sensor’s ID during initialization, but it’s not being read properly...
I want to implement deep sleep (wake up using RTC at a particular time interval), and determine the current consumption in nrf52833 dk. So I used the sample code first. When...
I’ve designed and fabricated two custom boards around the nRF52840 SoC.
I use an nRF52840 DK as an SWD debugger to communicate with each board.
Using nrfjprog...
Hi,
I have a custom board for the nRF54L15. I have already implemented LEDs and a button, which work fine. But I cannot get the PWM peripheral working, and I do not understand...
We are in the process of finalizing the RF transceiver chip for custom protocol development.
Please suggest the suitable chip and any reference implementations available...
Hello,
I am studying the materials in Bluetooth Low Energy Fundamentals.
I cloned the codes from GitHub https://github.com/NordicDeveloperAcademy/bt-fund

Would like to know whether you have a diagram for the RF pattern for nRF24L01. Like whether the node can receive other nRF signals 360 degrees around or should be at some...
Hi, I need to select the values for the crystal capacitors (C1 & C2) for a nRF51422 pcb.
From page 9 of "Crystal Oscillator Design Considerations" I see:
C1' = C1 +...
Hello,
I'm assessing various ways to authenticate/secure a connection with BLE on Nordic nrf51822. Our goal is to enable authenticated modification of a few values in a...
Hi
I see this in our own firmware and also in the sample HRS on the PCA10001
(If you try with the HRS app, then modify the app so that on BLE_GAP_EVT_DISCONNECTED instead...
I'm trying to get a simple, single shot timer working. The debugger never stops at a breakpoint set in my handler function, and an LED turned on in that function never lights...
Hi
i'm using nRF51822 with twi_hw_master from gzll library from SDK v4.4.2.33551. Code is compiling and linking, but not working. Gazell transmissions don't work when twi_hw_master...
Hello.
I want to protect nRF51822 ADC input from emergency case of overvoltage (up to 24V).
I don't want to use external diodes as any GPIO pin already has internal clamping...
When I use ble_app_hids_mouse demo to test my mouse sensor, it seems that mouse arrow will delay about 300ms to start send data ,at the beginning of movement.
When I cut...
Hi all,
I bought dev kit for nrf51822.
I got serial number for some projects.
Now I do not know where to build those project?
Should I use ukeil? How to install new device...
Hello,
I need to store some data to flash, and am starting to review pstorage. My question: how does pstorage know which blocks belong to which application? It appears...
We need some (5~10 pieces) nRF51822-CEAA-R (3.5x3.8mm 64 ball wafer-level chip-scale packages (WLCSP)) for prototyping. Where can we buy these?
The main suppliers like mouser...
I would like to host a project developed on nrf51822 on a public platform such as github. In this project I'll be using files from the nrf51822 SDK such as the CMSIS files...
I have create software for the nrf51822 (slave) that has
I also create a PC application using the master emulator api that implements the master
