To be able to upgrade FW through UART, a bootloader for nrf51822 is required in my project. I have tried out the example bootloader in SDK. But this example is using softdevice...
I followed the forum posts and nan-29 to get eclipse 4.3.2 to successfully connect to JLinkGDBServer via a Segger J-Link EDU on Ubuntu Linux.
I can start the GDB server...
I'm using Softedevice 6.0.0 and SDK 5.2. and Keil 4.7.
I Modified bootloader project so it compiles with both ble and hci transports. Currently I use button_0 and button_1...
I am working on the proj that needed 2 MCU and nrf51822 work as slave.
I would like to know any ref on how to firmware upgrade on board without external tool?
We're looking for a Nordic nRF51822 based low profile/small USB dongle that we can use for our iBeacon software.
It would need to come complete with casing and the ability...
Hi all,
i want to establish connection between two threads in cmsis-rtos, can i use
1) semaphore to do this?
2)message queue should be used or any other ipcs can be...
Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
In the past, I've been told I can bypass a lot of the Zephyr nonsense and use the HAL layers of the nRF Connect SDK directly. So if I want to use what was called nrfx_twim_xfer...
Hello,
I noticed the Audio application explicitly states that WAV sample rates other than 48kHz is not supported.
Is there any risk to modifying the code to support other...
Hello,
In my project, I use both a Bluetooth interface for communication and the PSA functionalities to store and read/use keys. I use the following configuration (excerpt...
Hi Nordic support:
Our product uses the nRF52840. During CE certification, the lab measured the BLE TX power in DTM mode. at –20 °C the power is 3–4 dB higher than at +25...
We are getting the following error when compiling from our static libraries.
undefined reference to `__device_dts_ord_168'
Our project consists of multiple static libraries...
Hello ,
We have recently started the evaluation of the nRF21540 Front-End Module and would like your guidance on the recommended SDK version for this device.
Currently...
Hi,
We're trying to implement HMAC signing on a Thingy91X but getting stuck each time on -134 errors. Having read the resource on your docs AI I'm aware of the limitations...
Hi, We are working with nRF52840 MCU with zephyr v2.9.2 SDK and Visual Studio IDE for debugging, Flashing, Generating zephyr.uf2 file. We took one example have configured...
Dear Nordic Semiconductor Support Team, My name is Iwo, and I’m developing a BLE central application using the nRF52840 DK with nRF Connect SDK v3.2.1. The application works...
Hello,
we are experiencing an issue with devices based on nRF9160 using modem firmware lib 1.3.6 and nRF Connect SDK 2.5.3 .
The problem manifests as a sudden inability...
Although the recommended circuit in the datasheet shows a 0402-size inductor, I have not been able to find any 0402 inductors that meet the required specifications.
Could...
Hi there,
We have been working on nRF9151DK (dev kits) containing the mfw_nrf91x1_2.0.1 modem firmware. Now we have some custom prototype boards ready (same SiP obviously...
I understand how to update the 9151 via LTE on the nrfCloud and now I want to update the 5340 via the same method.
I'm starting to understand the SMP Server example which...
Hi everyone, I’m looking into using LTE-M with nRF9151, and in that context I’m considering using an eSIM. I’d like to ask a few general questions around this topic:
