Hello,
I'd like to ask what is the data rate when using BLE OpenMesh network and how much it depends on network architecture.
I'm considering using it in a network consisting...
Hello Nordic Community,
I need to know how to import my PCB design from Eagle to CST Studio to simulate it and I need to know if the simulation step will be useful to enhance...
Hi.
I'm trying to get Apple notifications to nrf52. And specifically to listen both regular ANS (for android) and ANCS (for iOS) events depending what sort of phone is...
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...
I run the system_off example without the system actually going off, by removing all the calls to start the system_off worker. Instead of going to off, I let the system enter...
Hello
I played with the mcuboot_recovery_entry bare metal dfu sample. I noticed that if I sign an application image with an invalid key (invalid on purpose), the firmware...
I have been reviewing the antenna section in the datasheet of the BLE audio SoC nRF5340. The datasheet mentions a single-ended antenna output (on-chip balun). Could you explain...
Hi,
When the firmware is run in debug mode (J-Link connected), the system always works correctly. BLE initializes properly, and all sensors function as expected.
When...
Hello, everyone. I am an undergraduate student majoring in Mechanical Engineering in South Korea.
I am currently working on a research project to develop a PPG sensor using...
Hi,
(I'm assuming that the main() function of an application is actually executed as a thread.) I can't find any clear documentation that describes how a thread can suspend...
Hello team,
I am trying to interface the AT45DB641E flash with the nrf54l15 on a custom board. I am using the SPI00 instance.
Below is the configuration I set in .overlay...
Hi Nordic team,
We are working on a design that includes more than 50 peripheral node devices, each capturing sensor data and sending it to a single central receiver. I...
Hi,
I'd like to know how to tune the internal capacitance from the 32MHz crystal.
Specifically, I refered to section 4.12.1.1 Using internal capacitors in the nRF5340...
I am using the nrf52840 in QFAA package, and the external DMIC example receives audio data through the PDM interface. I noticed that the official documentation mentions support...
Hello,
We have been testing/validating sQSPI on nRF54L15.
We tested the sQSPI on two versions of our nRF54L15DK (0.9.2 and 0.9.3).
We are using this sample app: https...
Hello. I have one question.
When configuring RAM with the nRF5 SDK + SoftDevice, if I get the following error: APP_RAM_START=0x20006000 --------------------------------...
Hi,
I'm trying to program the nRF52840 Dongle (PCA10059, 2.1.1, 2023.26). I modified the Bluetooth: Central UART sample to use USB instead of UART and built it for the dongle...
I need to use one IO port of the nrf52832. This IO can not only detect the ECG signal but also achieve system off wake-up. The ECG signal is a PWM signal with a duty cycle...
I managed to somehow semi-brick an nrf52840. I've all but got the system/project working and wrote some instructions on how to install VSC with the appropriate toolchain and...
