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...

Hello and Happy new year!
My goal - to create ibeacon device. I've bought evaluation board, wrote firmware implementing beacon role and loaded it into PCA10001. It works...
I've modified the simple_uart example to use app_uart instead but I cannot get any data transmitting. I know the connections are correct because it works fine under normal...
Ole Morten has suggested using command-line GDB in a number of postings on this forum. Accordingly, I've tried to do that but always getting the following error ("Cannot find...
Dear Nordic
Does Nordic have a passive writable chip available (with compat antenae) that can be activated by mobile device bluetooth scanning event. The mobile device...

I want to develop a ble application.
This application can be shut down (system...
I've got my custom PCB design assembled. Attached segger jlink, but it detects only 0.1 V, although Vdd is 3V.
How is the power measured?
What should I read on SWDIO...
Dear
Is there a possibility within Nordic SoC to make a passive RFID Tag which will connect to SmartPhone via Bluetooth?
Just like µBlue Series, but smaller and using...
I found the "S110_SoftDevice_Specification_v1.2.pdf" but not the "S110 softdevice release notes" mentioned in a previous question about DCDC usage. Where is that doc?

I have been developing on a nrF51422 QFAAC0 chipset. That chipset required SDK 4.4 for soft device capability.
I requested the latest silicon (so I could develop against...
Hello,
I would like to build a tool in Python that allows sniffing/interaction with BLE traffic between nRFgo modules (nRF51822) and a Mac via the master emulator. I am...
I have bought the Bluetooth low energy evaluation kit nRF51822. It can be paired with a Nexus and a Sony Xperia without problems, but it does not appear at all on Samsung...
L.S.
Today I decided to have a look at SDK5.1.0 for nRF51822 which supports the S120.
It is deliverd as an msi file with (as far as I have noticed) no support for specifying...
