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...

I can find several starting points on the internet, but was wondering about your experience...
Hi all Nordic Developer,
Currently I am working on nrf51-dk(as a BLE central) and I wish to connect one of its pin to a power supply(as a input). If the power breakdown...
Hi, I am thinking of using the nrf24l01 board from Banggood ([here]) to build a transmitter/receiver set for r/c model planes. However one of the things I would like to do...
Hi,
Context
The chip will be a slave of a powerful CPU which is responsible for many coordinating tasks. The chip will connect the CPU via UART.
I am interested in...
hi guys
im using nrf51822 board sdk10 s130.
i want to use pstorage to store some data that could be preserved even after resetting the chip or after dfu. I have gone through...
Hi , I'm using SDK10 ancs example, and tried to add cts service. But after added cts service, when I disable iPhone6's BLE and enable it, the 51822 didn't auto reconnect....
We love the radio range of the Nordic bluetooth chips. I am looking to see if anyone is developing a long-range bluetooth pendant or wearable? if so, I interested in perhaps...
The NFC example (launch app) on SDK12 does work on my device. However, when I copy exactly the same code into my own project, the NFC does not work. The difference is that...
Hi,
We search some technical informations about Low Power mode PWM. What is the Max Frequency ?
