to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
Hi, We are developing a product which is reading RTDs and thermistors from the NRF52833's internal ADC. We're working on compensating for the intrinsic errors of the ADC and...
Hello,
In my device I have a nrf52840 which communicates with a STM32 via uart.
In my nrf52840 I use the MCUboot.
Is there any documentation or source code that would...
Hi all,
I am developing my own provisioner with the nrf52840 chip. My idea is to be able to add at least 2000 nodes to a bluetooth mesh network with the provisioner but...
Hi, I'm delevoping an appilcation which can generate one sample per 20 us (accomplished with timer0) and transmit one ESB packet when 20 samples are collected. Below is the...
I'm using NCS 2.7.0 and NCS 2.9.0 to read the BT stack version information on an nRF5340. See below for the results.
How should the fw_version, fw_revision, and fw_build...
Hello Nordic-team,
I´m currently developing an application which has been based on a 54L15DK an I´m using an overlay file for adjusting the ports to my own hardware. That...
I/ trying to read the ID of a Fijitsu FRAM type MB85RS4MT using the Nordic device nRF5340. I can properly initialize the SPI and transmit the RDID =0x9F command. The FRAM...
Hi,
I'm working on implementing a modem upload feature (using probe-rs) to be integrated into our production programming line.
Following the procedure described here ...
Hello,
I am trying to use the SAADC peripheral on my nrf5340dk without using the zephyr API; I am writing my program bare-metal. My goal is to set up the ADC in continuous...
Hi everyone,
I'm quite new to the Nrf Connect SDK and Zephyr.
I'm trying to implement a simple DFU (over UART) bootloader. The idea is that when the microcontroller powers...
Hello,
We have a water meter project that involves cellular and GPS functionalities, and we need to design the schematic. After reviewing the hardware design guidelines...
Running into a slight issue where the timebase for system (reference time + uptime aka k_uptime_ticks()) drifts relative to sensor sampling rates. Attempt to synchronize the...
Problem: Upgrading to newer SDK broke RTT processing of backspace character. Details: We had been using RTT with the v2.4.1 SDK (for our nRF52840 development) and yesterday...
Hello. I have a question about how to enable a 32 MHz crystal oscillator on a custom board? I have 32 kHz and 32 MHz quartz crystals on the board. I found the following config...
