Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...
i made this project to try to create RSC service on arduino
developer.bluetooth.org/.../runningspeedandcadence.zip
unfortunately the server starts but i'm not able to...
Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Hello,
We are currently designing the hardware for a production run of our product using the nrf52832 chip and would still like to have debugging capabilities with breakpoints...
I have been learning GCC+ Make work flow to build and debug nRF51822 S110-only applications based on the examples from NRF51 SDK v10.0.0. I started with ble_app_beacon example...
I tried to work application.
But firmware stops at advertising_init(). When I exchange advertising_init() and services_init(), firmware does not stop.
why ?
S110 v8.0...
Hello,
My device is nRF51822 SD110 8.0.0.
The problem occured after firmware update in bootloader (own, not SDK) with readback protection enabled.
So bootloader connects...
Hello,
I am currently finishing my deploy script and I am currently using nrfjprog to write some custom UICR data. I have a contiguous region of memory to write but I do...
Dear Nordic team,
Beside other persistent issues with your proprietary DTM command for setting Tx Power (see here and here ) I've found that default Tx Power in ble_dtm...
How do I add multiple devices to a whitelist (as the central, adding peripherals), then use the white list for multiple connections? I have read both

I have nrf51822 QFACA1 and STM32f407VG. I'm programming nrf51822 QFACA1 using STM32f407VG SWD pings. And now I want programming BLE nrf51822 QFACA1 but I can't find any working...
I bought MOD-nRF8001 BLE Module for prototyping. I gave 3.3v Supply to modules's 3.3V pin & GND to GND pin. But, I cant figure out weather mODULE IS ON OR OFF. Its unrecoverable...
Hiiii
In our industrial product we are using nrf24l01+ on PCB which will be going to fully coat with epoxy material while manufacturing. My question is that , whether this...
I have modified the ble_app_hrs_c_s130_pca10031 example to run without external RTC and collect only battery status data from BLE peripherals that have a service with UUID...
Hello,
I tried the example ble_app_multilink_central (SDK 11.0) with S130 soft device. My requirement is that nrf-dongle should work in central mode and it should connect...
Super general question :)
Our current products use nRF24 chips (paired with 8bit AVR's) and we're very happy with performance.
For us the key requirements are low latency...
Hi all, i am trying to load this example on the smart beacon kit; i followed this guide step by step ( devzone.nordicsemi.com/.../) but the problem is the if i load the precompiled...
Hi all, i want to use the internal bluetooth of my laptop to receive values of a sensor on the nRF51 DK, and save them in a text file. How can i do this?
