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.

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, I'm developing ble applications.
But there are problems on calling Ble APIs.
If I call the functions that conatins bt_le_adv_start() in main loop(Maybe main thread...
Hi,
I have a BLE interface with services and characteristics and I want to have different level accesses for my characteristics with for example two levels:

Hi,
Setup:
nRF NCS 1.9.x and nRF NCS 2.5.0
nRF5340 and nRF52840 both with an external crystal attached to HF clock input.
Problem:
Inaccuracy in timing of UART at...
This is sort of a hardware question, involving the RADIO peripheral in the nrf52(840) line. The question is simple. Is there any limitation on when you can change the TXPOWER...
I have a driver for a Piezo buzzer running on bare metal that I would like to port to the nRF connect SDK. The existing PWM-based driver in Zephyr does not fulfill my requirements...
Dear Nordic Team,
I want to connect my nRF9160DK board to my nRF7002DK board and get a wi-fi location. I've followed samples/cellular/nrf_cloud_multi_service as sample...
I have a question about Serial Modem firmware and the AT#XCMUX and AT#XPPP functions.
Are these commands available in the Serial Modem example in the Quick Start?
If I...
Hello,
I've been working with nRF9160 for a while now and wanted to let you know, I love this little piece of hardware. The possibilities, the small form factor, the power...
Hello~
I am developing nrf52840 with zephyr ncs tool chain v2.7.0 and SDK v2.6.1.
Our hadware is very simple, just a power IC, a nrf52840 and a G-sensor.
Our pre-production...
We have used zigbee sample for coordinator we did many changes in that like subscribing and sending values in UART when any new device gets added.
but noticed ZB_ZDO_SIGNAL_DEVICE_ANNCE...
Is there any plan to support Bluetooth Channel Sounding in Zephyr OS apart from nrfConnect SDK? If so, when can we expect a pre-release version to be available?
I am using a nrf52833 with NCS and was wondering if there are events I can subscribe to (or polling if events don't exist) that will notify me when USB power is connected...
Hello,
after some trial and error, I managed to use the "Bluetooth: Direct Test Mode" example with NCS 2.7.0 (Sysbuild) and USB.
Now I'm questioning myself how to correctly...
Hello,
I want to know how I can complete the qualification process. I already have a Bluetooth account. I tried to go through all the steps, but the only things I needed...
