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...

I have everything working nicely with gcc, my own Makefiles, and the Nordic SDK12.2. I'd like to move to CMake to better automate my process (in particular, compiling one...
Hi
for few days I seem to got stack in using together UART and radio on nRF21LE01 in ESB mode
and I suspect irq_flags = hal_nrf_get_clear_irq_flags(); to be cause of my...
hai,
i am using mbed to program my nrf51822.
i need the following requirements
1.store some data on nrf51822 flash memory using pstorage .
2.setup bonding for security...
It's my question. I use saadc single mode from nrf52832 to sample voltage .When the original voltage is 24 V ,measurement of the pin is 2.8v,I set the resolution to 10 BITS...
hi,dear engineers,
i use the example experimental_ble_app_buttonless_dfu of nRF5_SDK_13.0.0_04a0bfd,
on the PCA10040 board,Now,i'm sure that I am flashed Softdevice,app...
hi
I have designed a small PCB with the NRF52 chip on it and kept few ports for some peripherals. Apart from that I only have 4 pins that I can connect to, UART-Tx, UART...
Hello,
I'm wondering if my nRF DK51 is not broken as it behaves quite strange when trying to connect with a BLE Central (iOS and Android devices). For most of the part...
I am trying to track down a power usage problem with my code. When I started using SDK 13.0.0/S140 v5.0.0-2.alpha on a PCA10056, the power usage went up in my app. I see that...
I'll try to simplify my project as much as possible to make this understandable.
I'm wiring an nRF52 PCA10040 board to an iCE5LP (Lattice) FPGA.
I'm having an issue with...
I have an after market breakout board for nrf51822 with a usb-to-serial chip (cp2102) that I bought from Amazon . It should act as an NRF51 USB dongle (pca10031-like) but...
My pc server should send information to nrf52832 by ECDH, then I create a dll file from micro-ecc. However,the result in windows is not the same as the result in nrf52832...
