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...
I've a scenario where BLE central has registered for notifications on some characteristic of a BLE peripheral. The frequency of change in data of this characteristic is very...
Can a BLE peripheral listen for scan requests or any commands from BLE central without making any advertisements? If this is possible, then it would save on the transmission...
Hi,
I was in a process of developing a central device with nrf51422 in PCA10028 board with NUS service client.I use SDK v12.2.0.We have an example code in the library which...
Hi:
I set up a peripheral on nrf52832 and add beacon_info data as Manufacturer specific information。The version of softdevice is s132.
memset(&scanrsp, 0, sizeof(scanrsp...
Hi,
My sensor uses SPI communication and need 32.768kHz external clock pin FCLK , I connect 32.768kHz clock to XL1 and XL2 but my problem is which pin can I use it for...
Hi All,
I've integrated the flash routines from this example:
github.com/.../nRF52-fds-example
into my project, and am having problems figuring out the architecture...
Hello,
I've done this with an Arduino and 1Sheeld Bluetooth LE shield, but want to try with the nRF52 dev kit. Just looking for any starter code/examples/tutorials to help...
I have a piconet of 4 devices, where 1 device is a master and 3 devices are slave.
Communication continuously occurs between master and the slaves.
But then the master...
After looking at Nordic's Bluetooth 5 implementation for nRF52840 and other chips -- it appears that Bluetooth BR classic is not available. All I see is BLE and BLE functions...
We are working on a project using nrf52832 module and GPRS device. Here we are facing a challenge in updating the firmware to BL652 over GPRS and server.
nrf52832 is connected...
Hello, a quick rundown on the problem here:
New versions of Softdevices S140 corrected an error and now correctly ignores writing to cccd descriptor using write instead...
I have 4 devices communicating in a Bluetooth piconet, where 1 device is the master device and 3 devices are slave devices.
I want to time synchronize the 4 devices to...
Hi,
I'm using the S132 v3 and wonder about the impact of DLE on scheduling.
In the chapter on Scheduling in the softdevive specification is writen that multiple peripherals...
