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...
Hello I have a custom board with the following dts My zephyr app crashes in bt_enable() Note that uart0 TX pin 8 is used by gps_vrtc_en but uart0 is not defined. Same crash...
Hi
I have been using my out of tree driver for my BG95 module, which I have copy pasted from the zephyr's quectel_bg9x driver (drivers/modem/quectel-bg9x) and its required...
Today I opened VS Code to find all my Zephyr/NRF #includes have the red squiggly lines with an error such as "cannot open source file zephyr/types.h". Right click -> Go to...
I found this in nRF5_SDK_17.0.2_d674dde/components/libraries/memobj/nrf_memobj.h :

Hello,
We are developing a system that have the nRF5340 as a part of several MCUs, and we want to be able to upgrade both cores.
According to this: DFU for the nRF5340...
Hi,
I found that the NRF 54l15 can only estimate distance based on channel sounding and RSSI. On the bluetooth website it mentioned channel sounding accuracy being around...
Hi all,
It is a common convention to configure the I2C SCL signal to be push-pull instead of open-collector if there are no other I2C masters in the system (saves a pull...
NRF52840

App based on ble_app_multilink_central.
I have tried to build a bridge between BLE peripheral and PC.
I have spend so many time on PC side app.
The...
Dear Forum,
I have an nrf54l15 device and I would like to send a pure sinusoidal tone and measure the phase difference, retrieve I/Q values at the other device. This is...
Hi! I am designing a nRF54 based motion tracker that has an IMU onboard which can take an external clock signal for improved timing accuracy. Initially I had thought of just...
Hello,
I am having an issue using GPIO P0.03 as a button input in my design. Unfortunately, I did not notice that this pin is marked as a dedicated pin for the GRTC peripheral...
Hello Nordic,
We have recently purchased an nRF52840 Dongle. We were able to sniff the BLE packets over the air. So it is found that all the packets that we are able to...
Hi! It seems that I may have uploaded a non-working application to the Thingy91x. Therefore Device is not conectable via USB. The device is responding only in "MCUBOOT" mode...
Hello all, I am writing this as I am very new to Studio visual code, nrf connect, and many various things used in this project. Currently I am using the two samples given...
dear all,
We are fighting with a problem that defied every effort to solve it so far, so we are asking for help. Our custom board is based on the nrf5340 SoC connected via...
