Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi.

Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.
When...
Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
Hi, Our nRF52840 (NCS v3.4.1, SoftDevice Controller) is a central that connects to smartphones running our app (phone advertises, nRF52840 initiates). About 12% of connections...
We are evaluating separate anti-rollback counters for this nRF5340 application-core boot chain:
NSIB/B0 → updatable MCUboot S0/S1 → application
We want to preserve authenticated...
Hello,
we are designing an open-hardware set of motion sensors for veterinary gait examination, NIC-Strelka: 1–32 identical units on an animal, each with an nRF54LM20A...
I'm working through the Cellular IoT Fundamentals course. In lesson 7 exercise 1 a modem trace must be captured. I'm following the instructions but the modem trace capture...
Can I copy the ESB code from SDK v3.3.0-preview3 into SDK v2.9.0, and then get the functionality in esb_ptx_ble & esb_prx_ble?
Is there any way to achieve it quickly?
Hello,
While evaluating Channel Sounding on the nRF54L15, we found that the IFFT distance from the cs_de library can collapse to a few tens of centimeters when a contiguous...
Summary
On a small fleet of identical nRF52832 units running the same firmware (NCS 2.5.1, SoftDevice Controller, BLE peripheral, LFCLK = RC with calibration), individual...
For the connection (peripheral) tab of the online power profiler, I have a question on why if my TX payload is 216 bytes which fits within the LL PDU size, the payload would...
Hi!
I'm working on direction finding. I'm using a nrf52833dk as a beacon, a nrf52833dk and a Direction Finding Antenna Board (PCA2005) as a locator for a bluetooth direction...
Hello Nordic Semiconductor Support Team,
My name is Marius, and I am the founder of AIDA AS, a Norwegian engineering company working with industrial engineering, HVAC systems...
I have two questions: 1. The MCU platform is Apollo4MP, and the battery must be customized with a capacity of 28mAh. The PM model is nPM1300. When using its battery capacity...
Hi,
just got my PPK2 and noticed some strange behavior:
the only thing connected is USB data/power, no DUT. Power output is off. If you start logging it displays some...
I am seeing a reproducible interaction between asynchronous UART support and the TWIS peripheral on an nRF52840 running NCS v3.4.0.
The application uses nrfx TWIS to implement...
