Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
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...

Hi
Does the CryptoCell in the nRF52840 support secp256k1?
In this documentation it says at one point Koblitz curves using fixed parameters, up to 256 bits, are supported...
I used to do with the iso7816 run on nRF51822 SDK9 and S110_v8.0. However,as the BLE stack is running, the iso7816 interface clock signal is abnormal. as the picture below...
Hello!
I have the board PCA10040 (nRF52 DK).
I designed two different programs:
SPI: I'm using the SPI communication to communicate with an external sensor (accelerometer...

Hi,
I noticed weird behaviour on nRF52840 when using LE Coded PHY.
Connection access address is configured as logical address 1 and it works fine when using 1M and 2M...
Hi,
Can we use nRF in vehicle to vehicle communication V2V ? And how max nodes can we have ?
As I know, the nRF don't need authentication when we send data, is it true...
Hi Nordic,
Device: nRF51422. Protocol: ANT+. Softdevice: S210
We want to do the EMC test of our custom board and we would like to know at least an approximation of what...
Hi all,
I'm using nRF5 SDK V12.2 to do the OTA for nRF52832 . In general, it's ok. However, if I close the bluetooth function on the phone or close the DFU app from the...
Hi there,
I'm using the PPK (v1.1.0) to measure my nRF52 DK (v1.1.1). My sample programm is very simple: set up the LFXO, RTC with 8s CC-periode and the BSP_LEDs:
const...
