While using the nrfConnect tool inserted into the Visual Studio code, I believe I just need to select the board target of nrf21540dk/nrf52840 and the normal prj.conf and the...
I'm trying to setup an nRF52832 to drive 127 ws2812 by using PWM. It seems the bit-by-bit method is too slow for the 1.25uS period. pwm_set() is using somehow ~5ms, so that...
Hello,
My team and I are working on a project where we need our nRF5340 to send data via UART from the board to a RaspberryPI. We designed a custom PCB with the chip and...

I'm attempting to troubleshoot why my HM18 doesn't connect to the ESP32 over BLE. I'm now deep in the rabbit hole that is BLE sniffing so now I'm trying to determine if the...
Hello,
I did a side by side comparison of the latest nrfutil v6.0.0a0 vs v5.2. It looks like v6.0.0a0 is much slower.
Looking at the log from the target device, it looks...
Hi,
I have installed Embedded Studio for ARM v4.22. However, the studio crashes when I select 'Activate Your Free License'. Reinstalling does not help, and neither a different...
Hi,
In order to read values from TH02 sensor(Address: 0x40) I first need to give a command i.e. write 0x01(for temperature) and 0x11(for RH) resp into internal CONFIG register...
What is the least expensive J-Link Model is required to program a nRF52840 on a custom commercial PCB?
I see that it is a ARM Cortex-M4 core, but I want to double-check...
Hi
Im using nRF52832-QAAB0. SDK 15.3. Softdevice is running.
With debugger connected, calling nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_STAY_IN_SYSOFF) will assert in...
Hi everyone. Do you know any example of some over the air FW upgrade of nrf52832 chip via ESB protocol. As I understand it should be some combination of bootloader with DFU...
Hello,
We have selected nRF solution for our next product line and currently evaluating the software/SDK setup for that.
We are testing following SDKs:
nRF5_SDK_15.2...
in SDK 15.3.0, no eddystone lock event (NRF_BLE_ES_EVT_LOCK) is triggered after the unlock key was changed.
according the eddystone configuration specs:
A single byte...
I use example ble_app_uart, SoftDevice sdk 6.2.1, when receive data from bluetooth, then drive IO pin 18 to send infrared wave.
received data is Infrared raw formate, which...
Hi,
Our product uses Fanstel BM832 chip. As per https://www.bluetooth.com/develop-with-bluetooth/qualification-listing/qualification-listing-fees/ , should we opt for Innovation...
Hi
I am using TH02 for temp and RH measurement
I understand I must use TWI provided in SDK. However, I a working have c++ library(Wire.h) for I2C that I used with Arduino...
Dear All
I am right now working on BLE development with nRF52840DK. I checked a number of materials, including official specification from Bluetooth SIG, but none of them...
Hi,
I need to read a couple of external inputs - think buttons (although it's actually a sensor with relay output). It's for a prototype obviously.
I need to connect at...
