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

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...
Hi everyone.
We plan to work with nrf51422 and we need two BLE devices, One implements Peripheral role, another one implements Central role.
I would like to know if...
Hi,
I am migrating to the latest code versions (both SDK and Softdevice) but I am having issues when I start the notifications on a BLE app. The errors I am seeing are...
I have an application that uses the soft device and RTX RTOS. I am seeing a behavior I can't explain.
I use sd_app_evt_wait() in the idle thread after I have turned off power...
I downloaded the nRF UART 2.0 app for Android to a Samsung Galaxy S5, which is running Android 4.4.2. After the app attempts to scan, it never discovers any Bluetooth devices...
I have the RedBear BLE shield running on an Arduino Leonardo. I am using the ANCS Library from here: github.com/.../avr_nrf_ancs_library and have updated it to run the latest...
Hello,
I am currently working on a project that requires my analog signal to swing below and above ground. I was wondering if the ADC of the nrf51822 would be able to support...
I'm new to the Bluetooth LE world, and Nordic in particular. We have begun developing a system that acts as a Bluetooth master, and I am trying to figure out a way to test...
Hi everyone, I have just started using the s120 softdevice to implement a Central BLE device. The starting idea is to start with scanning and reading the advertisement data...
Hi,
I have seen several answers about how to achieve a higher data rate and I just want to make sure what I understand is correct.
I am using nRF51822 chip and the dongle...
I am developing a product using nrf51822 v5.2 SDK.The question is that Ble will automatically disconnect in some minutes after normal connect OK.The message by Sniffer is...
Recently while debugging my application i noticed strange behavior:
i set watchdog timer to restart application if my peripheral is not receiving any data for some time....
