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

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...
Hi,
I enable the watchdog in the application image, then call soft reset to enter the bootloader, the bootloader execution is also normal, until the watchdog is reset. ...
Hello!
I have a situation where a chip is connected with an antenna on a u.FL slot, what I want to do is to remove that antenna from the chip and connect my nrf52840 to...
Hi,
I want to send the I2S MIC Raw data through Ble by using ble_nus_send. I have written one application but it triggers a Cmake error. I have attached the log below...
HI I'm using the nrf5340dk, and I'm able to flash the application core with code that toggles the LEDs.
But I'm not able to flash the network core. I've specified in the...
Hi, I'm currently designing a system which requires Heart Rate monitorization and I'm using the MAX30101 chip to do so. I will be using I2C communication and, therefore, based...
1. We use code similar to the existing sample code to repeatedly sample a 0 - 2.25V voltage range using the SAADC. 2. Settings: 30s interval, single-ended input, burst-mode...
Hi All,
I'm looking for a PC based tool with similar functions as nRF connect. Our manufacturer is developing a functional test fixture which will PC based and will be...
Hello,
I'm looking for reading the sent data from an old embedded autonomous nRF905 (which act like an active tag) and I thought I could use this convenient-looking USB...
Hi,
I am using nrf52810 with custom board and i want to create OTA file for custom application. while compiling the bootloader to get hex files, i am getting error as "Target...
Hello Nordic support team,
Forgive me if I am asking a stupid question.
In the source file ble_conn_params.c, there is a function called ble_conn_params_init() and I...
from the datasheet we see that this device can operate at 1.8V or 3V3 (or anything in between).
We can also check supply current on the mRF52DK which runs at 3V3.
How...
Hi everyone,
I would like to measure the total current consumption of the board in order to get an estimation of the battery life. I am using PPK-2 and nRF Connect Power...
Hello Everyone,
For my project, I have to make my BLE device to advertise itself for a period of time and transit to "scan" mode to scan for other device for a period of...
I am getting this fault when i try to run a observer handler where i have implemented semaphores.
And i cant figure out what this error code means
Thanks in advan...
Hello,
I am currently trying to run this ble_secure_bootloader . I am using SES V5.68 with the nRF52840 SoC and I am using nRF5 SDK version 14.2.0. I have also adjusted...
