We have previously used nRF52840 and for the latest iteration of our board design we are updating to use nRF54L15.
We are aware that for nRF52840 we could map any pin to...
Hi,
I faced with an initialization issue of combination two features: MCUMGR and UART_ASYNC_API. I get a crash right after the FW starts. It looks like the SW configuration...
Can anyone clarify what information is stored in the nrf9160 chip barcode? For our manufacturing tests, we'd like to use a barcode-readable identifier on each board, and the...
I am adding Softdevice BLE to an existing firmware build(without softdevice, only USB) using Visual Studio and SDK 17.1.0 (Qorvo), on a Murata 2AB,

Hello,
I've inherited a project to create an iOS app that can communicate via BLE to UART RS232 to devices in the field using a proprietary protocol and at 115200 baud and...
Hello, We are using a nrf7002 for wifi only alongside a nrf5340 host MCU on a custom board. We are testing the wifi connection using the sample `nrf/samples/wifi/shell`, with...
Hi all,
I'm working with the nRF9160 DK and running the AWS IoT sample from the nRF Connect SDK v2.7.0 ( 5cb85570ca43 ). The device connects to the network and AWS IoT Core...
I'm working on a product that is somehow related to geolocation. As part of it, RSSI measurement is sent back at high frequency to the central. Currently based on nRF51822...
Newbie here hoping to get some direction on how to properly setup a timer to have a timestamp displayed for DEBUG messages. I am working on a PCA10040 board. I tried looking...
Hi,
I have some basic doubts in installing the power profile on nrf52Dk(nrf52840). I'm trying to use it on my central device which has its application FW running. I have...
what is the sending data rate of the sd_ble_gatts_hvx() ,why i use sd_ble_gatts_hvx() send data 600Byte per second, it lost data again . it can be use yes or no ?????????...
I can copy a Hex file from a Mac to the mbed USB drive and the code executes correctly. However, if I upload the hex file from any windows PC in our office (Windows 10) the...
Hello, I am trying to generate pulses with the nRF52832 chip.I created a basic setup for test purposes; I simply connected a LED to the PWM output, but even though I put 0...
Hi,
I have designed the Circuit using NRF52832 BLE and AT8010-E2R9HAA RF ANTENNA and tuned the circuit accordingly. Since the antenna was not available so I placed other...
I'm relatively new to development on the nRF52832 and I'm trying to find information on how to use the sleep mode with the SAADC.
Goal: The micro should be in sleep mode...
Hi,
I am trying to create a BLE node which can perform dual role(advertising/scanning) to create mesh of multiple nodes. I am planning to do it with the help of timer....
the project has a problem with DMA,the detail is:
on the board,NRF52832 and extern chip communication with i2c bus,the chip through a pulse wake up nrf52832,NRF52832 start...
I have NRF51822 Controller(custom board,S110) used to send some sensor data. i can able to receive data in android and ios. now i want to communicate to Laptop which has internal...
Hello Everyone,
I am new to nrf51822 (using S130). I made some custom service that accepts float numbers.
This might be noob question: I want to send float values from...
We are developing a custom ble service and profile however having printf makes our lives that much easier so we are trying to incorporate it purely for testing purposes. ...
Hello,
I'm trying to optimize my application :
I have a central (nRF52832 s132) which communicates for a short time to a peripheral (nRF51822 s130) and then disconnect...
