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...
Is there such a thing? For ultra-low, harvested power, how do you recommend powering the nRF5x: load switching Vcc or leaving Vcc connected and hold the reset pin low until...
Hello,
I have got the nRF52840-PDK, and I usually use CrossWorks, so I spun up a new project based on SDK 13, examples\peripheral\blinky and flashed this using default...
I would like to connect n antennas (through RF switch) to a single nRF52 that would do phase comparison between the n received signals. This is something related to I/Q sampling...
I know it is a pretty basic question but I can't manage to understand the documentation enough to pass the tutorial predeterminate code. If someone could help and tell where...
Hi,
I am trying to write a program which send data through notification. All is working, excepted that once the notifications are done, the device automatically disconnects...
I have an advertising device (NRF52DK+SD132_V3.1.0+SDK_12.2.0) where I whitelisted an address corresponding to my NRF51 Dongle (0xDA509C569622).
While the dongle is initiating...
Hi, At the moment I am using nRF Toolbox to upload DFU *.zip files to our devices. We have been finding that the devices will become unresponsive after a firmware upload,...
Hi!
I have trouble in flashing a simple nrf51822 via the nrf51-dk.
Can anyone ensure me that this simple wiring should be able to upload an hex file onto the nrf51822...
The Peer Manager is currently in experimental state and is not recommended for production and same for the device manager for some sdk.So which SDK should be preferred
Hi,
Im using S130softdevice.i wanna make dimmer by using experimental_ble_app_blinky project on gpioet
