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,
I'm developing custom PCB with nrf51822 (low voltage mode) and I have troubles with flashing the chip. I cannot see the chip in nRFgo Studio. I can flash original devboards...
Dear SOC developpers,
As many kickstarters i bought an RFDUINO kit, then I made a cool prototype thanks to the easy Arduino compatibility. I'm now thinking of industrializing...
Is there a simple software code example how to configure an interrupt handler for a single GPIO-pin? I am using nRF51822 chip with softdevice S110 and the interrupt source...
My question a little weird. Because I am super beginner about BLE. So what I want is how to write string data. now i am looking to information about this. I cannot find it...
Hi
I'm trying to implement bonding in a device based on the S120. As counter part i've used a S110 device or an iOS device (realized with LightBlue App).
While searching...
