I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
We have an use case that we may need to support up to ,say 500 sensor nodes and it may be added or removed dynamically. And we should collect all sensor data within 3 seconds...
Hi all:
Based the descriptions in data sheet, the GPIO9 and 10 are set to NFC antenna pins by default.
And I cannot control these 2 pin correctly by configuring the pins...
I want to use NRF51822 to advertise is door close/open. No need bidirectional data sending.
Only one way from NRF sensor to mobile phone app.
Actually I have only two different...
I am using NRF52 S132, and using UART service , but my phone is getting disconnected automatically after 1 or two minutes. I have seen this question asked in Forum but that...
Hi,
Has anyone test with Nexus 5X ?
I could not change connection interval 7.5ms, the interval is always 45ms.
Does anyone know how to change the connection interval...

Hello,
DEVICE_MANAGER_APP_CONTEXT_SIZE should be less than 256 bytes in size.
However, it seems to work properly (not fully tested) whith a size of 800 bytes, and no more...
Hi all,
I want to make sampling from microphone at 16KHz. So I want to first disable softdevice, do all measurements. An after that enable softdevice to transmit data. Will...
Hi,
Recently, I am playing around with the NRF51 dongle and trying to make it work as a BLE master.
However, when I run the sample code(e.g. advertising, multi-link .etc...
