Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...
Hi
I have been searching the forums, but were not able to find an answer to my question.

An...
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...
Hi
What is the nRF5340 PDM frequency max and min can be set?
Because below is our microphone frequency spec., we want to set PDM frequency into like between 450~850KHz...
Hello, I’m trying to understand the background of the issue described in nRF9151 DK v0.9.0 Errata . Could someone explain what caused it and, if possible, give an idea of...
Hi
I am trying to integrate a "TMP117" temperature sensor with an nRF54L15 using the existing Zephyr tmp11x sensor driver. The device is detected and initialized correctly...
Hi There,
We are currently developing a prototype using the mRF5340. (MDBT53-1M ) The key is to operate I2S at 192kHz.
Please let me confirm the following:
Is LRCK's...
Hello,
In previous NCS versions I know I have heard the test tone triggered by button 4 on Audio DK work out of the box.
I am currently experimenting with NCS v3.2.1/0...
Hi dear forum members,
I’m working on a firmware project for the NRF52840 that utilizes BLE, DFU, I2C, WDT, some cryptographic libraries, and a few sensor libraries. However...
Hey, wanted to know a few things regarding npm1300 1. Can it handle short circuit of it's buck/LDO outputs? Or we need to have some sort of protection for each buck. 2. If...
Hello,
I am using an nRF54LM20DK with nRF Connect SDK v3.1.1 and I am unable to establish I2C communication with an external DPS368 sensor.
The application starts correctly...
