1. Set up the development environment for the nRF52840 chip in VS Code, but encountered an issue where the chip could not be recognized. The development environment consists...
Good morning,
In my application (SDK v 2.8.0) I would like to disable/enable runtime the advertising for the mesh provisioning. The inizialization of the mesh stack works...
Hi,
Our project need 7 seperate PWM outputs, as the nRF52840 have 4 hardware pwm, I decide to use GPIOTE with PPI to create extra 3 pwm outputs to drive Red/Green/Blue...
Hi, last year the name of the Zephyr module "TraceRecorderSource" was changed to "percepio". In January a PR was accepted that updated the SDK's allow-list (west.yml).
We...
Four returned products after sale could not be turned on & charged normally. Preliminary analysis of disassembly showed that the MCU was damaged, and the MCU was cross-verified...
hi support team,
may i ask do we have demo on how to test remote provision in ncs2.9.0?
i assume there are two possiblilities:
1.
For server, we need add below settings...
Hello,
We are using a BLE module based on nRF52832 with a U.FL connector for external antenna connection. One of our automated tests requires we turn off/on the antenna...
Hi,
I need trigger repeated SPIM via PPI for a batch of samples until the given RAM buffer is full. Then I need start another round of batch SPIM with another buffer.

Hi,
I am trying nrf52832 with pca10040 board. My app uses s112 soft device and also SPIM0 to collect data from a slave device. No event handler has been used when initializing...
I want to know how to control BLE connection of nRF52832. I am using softdevice S132. I have a device that works centrally and a device that runs peripherals. When the peripheral...

We have managed to program a single serial number into the UICR, using our Development...
I am trying to interface I2C EEPROM (AT24C512) with nrf52840 and I am directly writing to and reading from the registers mentioned in the datasheet. I am seeing the i2c waveforms...
Hello -
We are also bumping into the problem described here , where it is not possible to initialize LESC when BLE is initialized from a FreeRTOS task. The nrf_stack_info_overflowed...
nRF52DK
external board with 51822 and mems
I connect my external board with nRF52DK as this (left is board, right is nRF52DK):
SWCLK -> SWDCLK
SWDIO -> SWDIO
VCC...
Hi,
I got some troubles on the communication distance between the two units which one acts as central and one acts as peripheral, I tried to adjust the BLE parameters the...
Dear Sir,
I have enabled my project for SPIM+EasyDMA.
I am configuring the SPIM transfer nrf_drv_spi_xfer with additional flags like,
NRF_DRV_SPI_FLAG_NO_XFER_EVT_HANDLER...
nRF51822 QFAA
At first I set up the RAM size to 0x1F80, it works fine. However, after I try to use RTT to print log, I got the compile error: region RAM overflowed with...
Hi ... how to set the password to secure the connection between the device and application . I don't want to anyone to connect my device , for that i am planning to the set...
I have a nRF52 DK. I'd like to debug my board which has nRF51822 and sensors, and has SWCLK, SWDIO, VCC, GND, RX, TX, VCC, GND. Please provide detail steps on how to wire...
I'm developing a central that discovers services in a peripheral. The services are both custom and standard BLE services. Discovery is working fine, but there is one issue...
Hello,
We are experiencing a rare condition whereby we read in raw Accelerometry data (758 bytes) over the SPI bus, and sometimes (rarely), we'll get a block of repeated...
