I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
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.
I am using S130 softdevice version.
Basically, I am using NUS Service and make a my own NUS central service as NUS_C.
It is correctly work at normal state.

Hi Team,
We are trying to store the audio that is being captured and transmitted by nrf5340 digital mic and then store it to connected android phone. For this we tried A2DP...
I test data transmission through NUS service as follows.
If data is transmitted 6 times in succession, the system crashes. No logs appear. However, the system does not die...
I would like to measure the current consumption of an nRF21540-EK (mounted on nRF5340-DK) using the PPK 2. I can't find any relevant documentation regarding the connections...
Dear sir or madam
We are designing a new project and need to transmit 2 Mbit/sec of data, wirelessly.
We would like to get your recommendation about a device and a protocol...
Background: My colleague encountered a problem on using GPIOTE for detecting multiple interrupts with the API from app_gpiote.c in SDK17. When there are more than 2 interrupts...
Hello everyone. I am developing a peripheral device capable of connecting to a central device. The device consumes 1.6uA on connection, but there are different current peaks...
Hi Nordic Team,
We have developed a project with the nrf52840 + nrF21540 FEM for an audio-related application.
We are in Production now. As part of the QC process of the...
hi team,
I using nrf52840DK controller and nRF5_SDK_17.1.0. I want to change PWM module Frequency dynamically (it has to change frequency automatically) at different time...
Hi,
simple question: Are the nrf_modem_at_xxx() functions thread safe? Can I use them to query command the modem from different threads without needing to lock accesses...
To the kind attention of Nordic support team,
Following PPI examples, I configured PPI so that an external interrupt (transition hi->low on a gpio pin) is triggering a...
Hi everyone,
I am new to the development and I am trying to connect my nRF52480 to my phone. When I open the desktop app for BLE connections, I cannot select the start scanning...
Hello,
I am trying to communicate with a BT832X module ( https://ro.mouser.com/datasheet/2/915/BlueNor_BT832X_datasheets-1518727.pdf ) using a PIC microcontroller ( http...
Hi,
I'm devlopping python (v3.9.6) software to flash nRF52832 using pynrfjprog (v10.17.3) package.
The soft is a loop trying to erase and flash. But while debugging...
Greetings Nordic Team,
I am trying to pass data from an application on a dk-nrf52840 to a nrf52840-dongle whose uart is connected to the uart on a microcontroller. Using...
Hello,
I am trying to interface nrf52840 with HMC5883L magnetometer sensor to read magnetic field x, y, z values.
When it comes to results, as far as i understood, values...
