we also produced self PWM for ADC wave form testing. when we stop transmission, we will get good waveform out, but when we starting transmission, output waveform shape is...
Dear Support,
I have some troubles with the Evaluation Kit for nRF51822 :
I use the broad as a central role with S120_nrf51822_1.0.0_softdevice.hex and example...
Suppose a nRF9E5 transmitter is set for continuous transmission on a channel.
A nRF9E5 receiver listening on that channel:
finds carrier and sets CD
finds address...
I will be deploying my nRF51822-powered devices into the field and the end user will not be able to have any physical access to, for example, power cycle the board. I need...
Hi,
We are using the ble_app_uart example in evaluation board to read data from some sensors and send it to the nRF UART V2.0 in Android 4.4. Every 20 ms I am trying to...
I am try this at nrf51_sdk_v6_0_0_43681\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard

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:
1....
Hi,
i'm using nRF52832 to construct an BTHomev2 sensor.
In development, we find the firmware seems to randomly fail in k_sleep(), but once we full earse the chip before...
I am trying to configure Analogin_rev pin as ADC pin and I did the code changes, but I am getting the error -22 while trying to Configure ADC channel. Here is the snippet...
Dear Nordic Specialist,
I am using two nRF5340 DKs running the Direction Finding connection-based Central/Peripheral examples, and I would like to evaluate the maximum achievable...
