Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
I am trying to create an nRF8001 based application that will broadcast battery levels (pipes broadcast, set), and give out temperature data (pipe indicate - TX_ACK) to connected...
Hi,
I'm using redbearlab's nrf51822 board. It is a arduino compatible board and hence it is using 0,1 (mapped to 9 and 11 for nrf51822). How do I make printf print to this...
An external PA/LNA is used to extend range of nRF51822, and S110 is used for BLE, How to switch between PA and LNA? and how to disable PA/LNA when there isn't transceiving...
Hi...
Can anybody help me to run ble_peripheral example (ble_app_hrs for S130). I have build and load the code successfully but cant see the advertisement. But while debugging...
Hello,
I would like to sample the battery level of my nrf52832 DK and send it through BLE. I have started from the example ble_app_hrs for SDK12.2 since the service was...
Hi,
Most of the sections of my application are functioning as I want it to, except these two (step 3 and step 4).

Connect device (with Auto connect...
I noticed while running a Bluetooth scanner app on my iPad, while testing one of my devices, that it was showing someone else's device in the locality.
What I found strange...
Hello!
I have:
nRF52840-Preview-DK (pca10056)
nRF5_SDK_13.0.0_04a0bfd (s140)

I have an interrupt coming in every 50-150 microsecs and I want to measure these intervals as precisely as possible.
I tried this with SDK12.2:
APP_TIMER_INIT(0, 5,...
We're trying to bit-bang SWD to program an nRF52832, and we're running into some problems getting the nRF52 to respond. One theory is we're not generating a high enough clock...
i just purchased the www.xcluma.com/bluetooth-4-0-module-NRF51822-2-4G-module-development-board-ble-4-0 this xcluma nrf51822 module , so how can i progarmme it . which IDE...
Hello,
I've noticed the following sentence in s132_nrf52_3.x.x release notes:
"Synthesized low frequency clock source is not tested or intended for use with the BLE...
I'm following the tutorial in the NRF52840 SDK on setting up a Thread Border Router here and I've run into some issues during testing. For one, I'm trying to resolve ipv4...
Hi,
I'm able to successfully enable Access Port protection, either using nrfjprog or by setting NRF_UICR->APPROTECT register to 0xFFFFFF00 in code.
But I have a problem...
Hello,
Since this seems to be a very hard topic to find info about (its very contradictory and confuse) I'd like to ask a Nordic employee directly.
I'm planning to build...
This concept keeps popping up when I'm dealing with mesh networking.
My guess is that, to avoid air collision, packets/pdus are sent on a randomized or predefined combination...
Hi,
I am using ble_app_uart for my development, in that I have buffer size of 2kB which will store all the incoming data and the data will be processed and send over NUS...
