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...
i made this project to try to create RSC service on arduino

unfortunately the server starts but i'm not able to...
Hi everyone,
We are currently at the stage of selecting a 3rd party nRF52840 module for our prototype. Maybe my question has an obvious answer but I want to ensure that...
Hi
I am evaluating this profile:
www.bluetooth.com/.../viewer
Is it availabile an implementation in nordic sdk of this profile?
Or something similar to have a reference...
Hello,
I'm using Segger ES 4.52 and I'm having some issues while doing step by step debugging.
It tells me that some symbols are not defined, even if they actually are...
Hello,
I am working with an nRF52 and two sensors using TWI. My code is based on the TWI_sensor example from SDK 12.2. I made an interesting discovery today when trying...
Hi, I am new to creating boards with RF capabilities, so excuse me if I get anything wrong or missed something. So, going over the reference layout for the QFN32 version of...
I am trying to use UART1 on nRF52840 to communicate with another device on a custom board. I am using Zephyr. I have successfully compiled code using the function uart_poll_out...
hello Nordic
i am using nrf52832, sdk 16.0,
i have a system which need to react to multiple external interrupts on multiple pins
i see that when ' nrf_drv_gpiote_in_init...
The nRF52 SDK is limiting the transfer size to 255 byte even if the HW supports bigger buffer.
This is due to a data type that is defined as uint8_t:
typedef uint8_t...
Hi,
I'm using nRF52-DK evaluation board, and ble_app_template_pca10040_s132 (from examples of nRF5_SDK_17.00.9d13099)
I'm designing an android smartphone as a central...
After moving to v1.3.0, my build fails, because the imgtool can't find the module cbor. I see some updates for zephyr that indicate cbor.py is now required, and it's included...
I would like to tightly integrate a nRF24L01+ with my microcontroller. I have read as much as I could, and copied as closely as I can, but the best layout required moving...
I have pretty much gotten my application fully ported and working on nRF52832. I am now looking at adding in DFU for OTA updates.
Can you confirm my understanding, based...
Hello,
We are trying to use the usb wakeup feature while also using the usbd as a serial port (over usb).
The rwu is registered on initialization in our firmware using...
Hello,
I am using a nRF52840 dongle to communicate between a laptop running Ubuntu and a phone running Android.
Right now I set up a UART-BLE communication using an...
Hi
I've been developing using an NRF52 DK and have moved onto my own design board, I have one small problem which I'm unable to replicate using the DK. On my own board,...
