We need to set a GPIO pin in MCUBoot to activate an external USB hub chip so the USB DFU will work. I would like to do this with code in our project rather than directly modifying...
Hello,
I’m working on a Zephyr-based application using the nRF5340 where I need to optimize power consumption. The intended behavior is:
The device should stay in...
According to the nRF52832 Product Specification, “A step increase in supply voltage of 300 mV or more, with rise time of 300 ms or less, within the valid supply range, may...

Hi,
I noticed in the nRF54L QFN48 reference design, for the NRESET pin, there is an RC filter (1Kohm series R and 3.9pF shunt cap). What's this for and is it necessary?...
Hello,
I am using a nrf5340 dev kit. When I use SPIM the output from the pins gives the correct hex values but the output's amplitude is only around 100-200 mV. I know that...
Hi,
I'm using the nRF52840 with the SoftDevice for BLE. In my system, it's primarily a BLE transceiver controlled via SPI by an external TI MSP430. We're considering implementing...
Hi,
I'm trying to configure the SPI by using the nrf_drv_spi. the problem that I'm facing is the configuration of the "spi_config.SPI_CPHA = SPI_CONFIG_CPHA_Leading" which...
Hi!
We are using ble_radio_notification for changing the advertisement data after every advertisement.
The problem is that it doesn't work, the device freezes when trying...
I have designed a custom PCB with Nrf52 for an ECG wearable sensor application and is trying to optimise the power consumption of the device. The application is to collect...
Hi.
I'm currently trying to scan beacons with timeslot example.
However, I found that there're more than 20% of loss while scanning beacons broadcast.
I think that...
Hi, I tried Adding another service to the LBS Program, but the chip is getting reset , i have another 16 bit uuid service with different base uuid, Its getting stuck at SOFTDEVICE_HANDLER_INIT...

im running one of example that its name is ble_app_template and when i run it , it show up for just one phone...
hello,
I want to change the advertise time out time by BLE_GAP_ADV_TIMEOUT_LIMITED_MAX.
Is there a problem with changing BLE_GAP_ADV_TIMEOUT_LIMITED_MAX to ex. 1000sec...
Hi,
I can use nRFgo Studio via nRF5x Bootloader to update application firmware(Hex file).
It look to be using "nrfutil.exe" to create a XXX.zip file and go through UART...
Hi.
I am on nRF52 DK (PCA10040 v0.9.0, s132 SD), SDK 0.9.2 and Linux (Ubuntu).
I am currently working on the SDK's example ble_app_uart.
I am only using gcc, and...
I was working with examples/ble_peripheral/ble_app_gls. In the SDK11alpha configuration, I paired the dev board with my Android phone running nRF Toolbox and was able to start...
Hi,
I loaded S110 v8 to nrf51. Then I loaded dfu_dual_bank_ble_s110_pca10028 bootloader.
With this setup, I'm able to download my application via the bootloader.

Hi,
Reading the nRF52 product specification, I see:
"If the antenna is exposed to a strong NFC field, current may flow in the opposite direction on the supply due to...
Req: from the cap-sense board, different tap will be done by user (like 2 times tap, 3 three times tap etc). so the Bluetooth board (nrf52) will receive these taps as interrupt...
Hello Devzone fellows :)
As you may notice, we have posted our first webcast: Interfacing with Nordic's Softdevices .
It's the first test run in a series in which we...
