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...

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...
So as far as I can make out, when I load a new application into the flash, the NRF52 will attempt to first load a secondary memory space and if successful, it will then replace...
Hi,
Right now i am using Blinky example in Peripheral section of SDK15 (S140). I would like to enable Coded PHY (BLE_GAP_PHY_CODED) instead of default setting (BLE_GAP_PHY_1MBPS...
Hi, I have problem with timer in nrf52810. My TIMER2 counts very slow. I declared it as NRF_DRV_TIMER_INSTANCE(2); and config struct is:
.frequency = NRF_TIMER_FREQ_16MHz...
Hi ,
I can compile and use the UART example but when I try to use it in my project I get some linking errors
I have copied and past all the sdk_config.h file to my project...
I am waiting for my custom pcb based on the nrf52832 to be ready and I want to test the flashing process. Is it possible to program a nrf52 DK with another nrf52 DK using...
Hello,
I was wondering if there is some way to program a device to act like a BLE slave, which would sleep and periodically wake up to stay in receive mode for a certain...
Hello, I'm confused what the NRF51422 uses for it's digital IO reference. So for example, If I use a 3.0V coin cell battery through its DC/DC converter: 1. What voltage does...
I download the SDK at https://www.nordicsemi.com/eng/nordic/Products/nRF5-SDK/nRF5-SDK-zip/59011 . When I used "nRF5_SDK_15.0.0_a53641a\examples\ble_central\ble_app_uart_c...
Hi,
I am using SDK10---->ble_app_uart--->pca10028--->s110 for non-invasive GLUCOSE measurement. I checked nrf_adc.h file & used adc_sample = nrf_adc_result_get(); for getting...
I am using nrf52832 development kit and softdevice v5.0.
I am using this code which I have attached.
I have added all require files.it might be not showing to you because...
My current setup is this:
I have a nRF51822 beacon (tiny coin cell beacon) advertising with its default settings. I have another board, a nRF51822 Development Kit, that...
Hi,
I have a customer request regarding ISP1507 module (with nRF52832 integrated) and battery information.
Customer want to have battery information using LED (bicolor...
Hi,
We are using nRF51822, SDK12.3, pca10028, S130 with "Red Bear BLE Nano V1.5" board. We try also in nRF51DK and our own board (designed by us) and the issue is the same...
Hey,
I'm trying to solve the issue of connecting a central device (nRF52832 running experimental ATT MTU example) with a particular peripheral device (also, nRF52832 running...
