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...
In connection with a nRF51422 evaluation kit, I installed the Keil development tool in a non default path then subsequent installation of nrf51_sdk_v4_3_0_27417 produced a...
How does the nRF8001 chip generate the passkey in the DisplayKeyEvent? Is it possible to set this passkey from the App Controller?
As I understand it, the SetKey command...
I find this strange but I can program the HRM demo fine but with my own code it compiles with no errors or warnings but will not program with Error: Flash Download failed...
Hi Nordic,
I want to develop a PC software that works as a master device which can scan for advertising packet, establish connection, etc. Basically, something similar...
Dear Sir,
After I remark this //BLE_GAP_CONN_SEC_MODE_SET_OPEN(&cccd_md.write_perm); and program it into nRF51822, then I cannot program it again. PC program report it...
I have modified the included HID mouse example to allow for left/right/middle mouse clicks. However, it is not clear to me how to set an event handler for both when a button...
What is the recommended PCB thickness of the nRF51822-QFAA Reference Layout? It'd be great to have a specification in the package including the full spec of the PCB material...
Hello Folks, I'm starting some work with the nRF51822 Evaluation Kit (PCA10001), but have very quickly run into a blocker when trying one of the ble samples. (I've previously...
With Soft Device 5.1.0 I generated the binaries from the hex by doing:
arm-none-eabi-objcopy -Iihex -Obinary --remove-section .sec1 --remove-section .sec2 s110_nrf51822_5...
Dear support,
We are in the design stage for a BLE application. We looked at different options. Although the NRF51822 seems better in specs. The TI parts CCxx offer this...
So far I have made a successful program that utilizes BLE to send and receive radio signals in Kiel. But I have only been testing this program by using the provided Master...
I just entered a Case to Nordic with this same question but do not expect to get a response over the weekend so I am posting here. I made the assumption that the Nordic Cases...
Dear everyone:
Now,I have a project which use Nordic product solution to developemnt.
And , We need your company to provide some information and solution.
