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,

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...
Hello,
We have many nrf9160 based devices currently on the market running for our customers. These devices are facing some problems that we are trying to debug right now...
I am working on nrf52832 based custom board which is configured to work as BLE peripheral and central. Peripherals like GPIO, SAADC, I2C, Timer and RTC are also configured...
Hi, I need to program my custom boards, i am using nrf52840 DK which switches programming from the internal chip to the external one based on its presence.
Is it possible...
hello. I developed and tested the ncs/nrf/sample/bluetooth/multiple_adv_sets example using the nrf5340 DK board to suit my requirements. I want to run the source by inserting...
HI all,
I've found that adding a 10uF capacitor to the 52805 beacon reduces the power consumption, especially after speeding up the broadcast interval (100ms broadcast interval...
Hi. I'm going to decode JWT (ECDSA sign) but I'm stuck. There is simple example to sign payload, but how can I decode JWT which I get from another device via bluetooth? I...
Hi I'm trying to debug the record_text example in the nrf connect sdk. However when I attached my nrf5340 dk and hit debug in the nrf connect extension, the process stops...
Hello!
I am programming BLE with the nRF52840-DK. [Toolchain Manager: v1.3.0, IDE: Visual Studio Code (VSCode), SDK: ncs v2.6.0, window11 pro]
I am using two nRF52840...
Hi,
I have ordered custom board based on nRF52840 SoC couple of times from JLCPCB and that included assembling as well. Unfortunately, 90% of the boards had floating aQFN...
Hi,
I'm using the Bluetooth sample called Central HIDS and want to develop a feature that stops BT scanning after a few minutes.
However, during development, I encountered...
Hello,
I have a question regarding the consumption of the nRF9161 DK board when it is under the following conditions: MCU on IDLE, modem off, wake on GPIOTE input (event...
Hello, I am wondering - Is it possible to program BL651 Bluetooth 5 with nRF52810 using pca10040 development board with nRF52832 on it and using
BLE HID Keyboard and Mouse...
Hi,
I recently started upgrading an nRF chip on old SDK to the latest nRF Connect. The device has only one button and currently uses a static passkey (written on the device...
