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...
Hi,
I have two BLE centrals and one BLE peripheral. Both centrals are in range of the peripheral and both want to connect to the peripheral at exactly same time. What central...
Hello ,
We are working to an OEM Security System project that is using BLE.
The system contains at least 2 modules that communicate using the BLE technology.
One of...
I am trying to run the example ble_app_hrs on the nRF51 dk PCA10028. I target and build the file, and I believe it makes it onto the device, as the old program on the device...
Hi,
when i program my eval kit using nRFgo studio, the chip dosen't work unless i do a hard reset OR put off supply and put on again.
Any idea ? My program, is dfu bootloader...
Hello Nordic Team,
I am sorry to say this, our development team found a major glitch in micro-esb communication protocol. we are in stage of pre-production of medical sensors...
Hi
We are thinking of using NRF51 for BLE and CPU capabilities. But we also need a Wifi add-on to connect to cloud.
What is the right chipset for this? Which ones are...
I have a demo(s110) set up with some custom services, and in them custom characteristics. The services each relate to a specific sensor element on my device, so have a mostly...
I'm using ble_nus_string_send() to send 15 bytes over BLE UART.
As expected it sends 15 bytes, however on occasion 14 bytes are sent instead of 15 bytes.
Would there...

I've been working through the tutorials on BLE Services & Characteristics. That's all gone fine for me. Now I'm adjusting the sample code to use different UUIDs for my own...
Dear Sir.
I have a question for app timer in nRF52 DK(pca10040).
I was called a example source(ble_app_hts) for nRF5_SDK_11.0.0-2.alpha.
And I add UART part for logview...
Dear All,
I have question regarding advertising in NRF51. I measured the power that be used when advertising using osciloscope and set the advertising interval of NRF51...
I'm having this event and I'm not sure what are the conditions required to trigger it, also what does it mean exactly since the documentation does not say more than a line...
I had attended the Nordic 2015 Tech tour in Helsinki and it was very nice of Nordic to give away nRF52 DK to all attendees. So far, I've been busy working with nrf51 but today...
