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...

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,
I just got a nRF51 DK and I'm trying the examples of nRF folder in the Pack distribution (SDK 7.2).
I can compile the Blinky project but its not working if I...
i have the nRF51DK that comes with the Segger j-link programmer. Can i use the programmer on the board to program a custom board i purchased from Nordic preferred vendor?...
Hi all,
I am using gcc for my Nordic project and I wanted to add the bootloader. After some reading and experimenting the bootloader worked. Now I thought of making a release...
Hello all,

Hi,
I need to develop a BLE service for file transfer between iphone and my device. I chose BLE because the files are very small in size, and as BLE does not need authentication...
Hello everyone,
I got a task which I try to implement using a NRF51822 iBeacon board.
The Task:
Advertise a Device and provide a mechanism to connect without traditional...

I chose which manufacturer...
Hello, I'm working with the EK PCA10003, that has the NRF51422. I'm trying to read the information of the accelerometer MPU6000 with an ISP interface. At the moment I cannot...
I'd like to use the GATT/GAP driver from an ARM based Linux system. Is there any possibility of getting a library compiled for ARM or (cough) the source code to build it myself...
I am trying to write my firmware in mbed instead of microvision. I have my own custom PCB w/ the nRF51822 and use SPI with different GPIO pins than the standard ones.
My...
On the following code I have a packet of 6 bytes that I write to a buffer. I pass the buffer as read_packet function argument. When optimized, the code doesn't work. I only...
It is possible to run easily a SoftDevice stack (e.g. S110) on nRF51422 using an accurate 16MHz external clock reference for HFCLK instead of an external 16 MHz crystal oscillator...
