Hello,
I’m trying to run the TensorFlow Lite Micro example (zephyr_samples/hello_world) on my nRF5340DK using nRF Connect SDK 2.6.1, but I’m unable to build the project...
hi support team,
when i testing wifi location, i found out one problem:
nrf_cloud_rest: Failed to encode location request, err: -12
that is this code in nrf_cloud_rest...
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...
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...
from training document from Nordic company(see the attachments),it mentioned that we can add scan response .but i can not find any information in BLE_HRS demo.could you tell...
Hello,
I made a PWM with the TIMER2 of my nRF51822 (with the SoftDevice) and was working fine, till I read that I should not use the "NRF_PPI" functions and use the "sd_ppi_XXX...
I've got an nRF51822 development kit that I'm trying to get started on. I've gone to Kiel and downloaded uVision 4 (mdk472_a). I install it with all default settings and it...
Hi,
I add UART support using IRQ on the "ant_hrm_tx" example code.
and I'm sending packet of 4 bytes that contains: Delimiter,HeartRate,Battery,Delimiter
the frame...
Hi, I am trying to test my UART using some simple loopback test, and I have noticed that the service discovery command of BLE will occupy the CPU a quite long time. I am just...
I was unaware that the 'manufacturer data' in the advertising packets is limited to less than a full payload. However, whenever I set it to >6 the program "crashes".

When I use keil to download the software to the chip, there are two questions:
like attached.
2.NRFGO CAN'T SEE J-LINK LITE CORTEXM BOARD
Is there any way to solve...
We have recently moved to a new PCB which puts the nRF8001 on the layout instead of plugging into a nRF2741 development module. The nRF8001 connects to a TI Cortex-M4 Tiva...
Hi, we would like to create a kind of game using 2.4Ghz emitters . The 2.4Ghz USB Dongle emits and the mobile phone detects the frequency + embed unique ID/code so we confirm...
To be more detailed:
One of my ADC pins will be connected to another device that could be providing a voltage of about 3V, but through a 100 kohm resistor. (actually it...
Dear Nordic Developer Zone,
Since I have implemented a timer with interrupt in my application, the debug mode if the Keil IDE stops working when I try to restart the code...
Hello, I'm trying to develop with the nRF51822 Eval kit and GCC and Eclipse. I've been getting some strange behavior and errors lately. I'm not really sure how to describe...
I'm a green hand HW Engineer.
I'm trying to compile, program, and run The Heart rate monitor demo though following the step in nRF51822_DK_User_Guide_v1.0.pdf .
