Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I used the sample code "Master Emulator->2.1.7.8226->Example code->nRFUart"
to develop a new project, and encounter some questions...

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...
dear friends ,
