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 created xml file for heartrate server using bluetooth developer studio and the plugin nRF8001_Arduino (plugin nordic semiconductor for arduino)

I am not sure if this is a limitation with Keil or Nordic SDK. I made another copy of ble_app_uart inside SDK_11 s130 and renamed it with a much longer name. I tested that...
I'm using the nRF SDK5 v11.0.0.
I'm trying to test out UART Logging in the simple blinky example bundled in the SDK.
I added NRF_LOG_INIT() and then a NRF_LOG("Testing\n...
Hello everyone,
I am trying to implement a bootloader to my application to be able to enter in DFU mode.
I am using nrf51822 (32KB ram 256 flash) and s130.
I have taken...
My understanding is that the nRF51 is known to need a fairly stiff external pull-down resistor on SWCLK to avoid noise putting the chip into debug mode. I note that the nRF52...
I'd like to know how to implement a bootloader for the Nordic SoC nRF51822-QFAA-R in order to boot the softdevice and some firwmare. If will be great getting an application...
Does nRF52832 have battery monitor?
I can't find in the datasheet if there is an externarl circuit to monitor the battery. I'm using a CR2032 coin cell battery.

Hi,
I'm developing some firmware that will hopefully run on a few different kinds of nRF52 device.
Is there a way of detecting if the DC-DC converter's inductor/capacitor...
Following situation:
My device acts as central (connecting to ble sensors) and as peripheral (transmitting and receiving data from mobile). Several services (Heart Rate...
Hello,
I followed this tutorial:
