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,

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,
we use the GPIOTE to get informed if the value of a GPIO pin gets from hi to low.
If this happens, the GPIOTE event handler will be called.
What will happen,...
Hi, I'm using a nRF52 dk board as a switch to control a circuit. The problem is I not sure which gpio can be used to act as a switch to control the circuit. Thanks.
I need to append another binary-file (image.bin) to the generated bin-file from my own nRF makefile Project in Eclipse with Cross ARM GCC. My research showed me several possibilities...
Hello,
I have a standalone application which incorporates 3 public BLE services and 2 services with custom UUIDs.
Today I tried to extend the buttonless DFU example with...
Hello,
I have installed Ozone (V2.22g) on Kubuntu (16.10 64bit) and attached a nRF51DK via USB. I can successfully run a test program using nrfjprog with the following...
Hi,
I'm not sure if I understand the new reference layout correctly. There are new NP0 12pF capacitors on pin 25 and pin 26 to suppress the spurious emission, but are they...
I'm trying to flash the nrf52832 with a SWD debugger called Atmel Ice . As a reference, I have the Laird BL652 dev board .
I was planning on flasihg the nrf52832 by using...
Hey,
Could you please explain, in your reference designs, why you suggest to use solder mask clearances that cannot be produced?
0.045mm is not possible produce and...
BLE_Nordic.zip Hi,
We are a couple of students trying to implement NRF8001 in our project, we made a SPI setup on our Atmega328p to communicate with the NRF.
After sending...
How does a multirole component behave if it is set to continous scan and advertising every 400 ms? This is pr. definition a contradiction!
My question is whether it is...
hello, i am implimenting ir with nrf24le1 but after adding the transmit.h,transmit.c nordiac_common.h and lib_ir_common.h the code is compiled successfully but it shows this...
Before(SDK11), I enabled uart and used printf function to print out log message to UART.
But, in SDK12 I can not see printf message. But, app_uart_put is working.
Where...
