I'm looking into a rare issue on the BBC micro:bit V2 which uses the nRF52833 as its (application) microcontroller. I used to be familiar with some CPUs from the 80s but my...
I have shifted from silicon labs for BLE project. In Si labs we have burn BLE bootloader and BLE application separately. Do i need to do the same here in nrf controller? If...
I am unable to detect any i2c device when connected to the Nordic nRF54L15 DK kit. I have change the voltage from 1.8v to 3.3v and Tried and explore other pins in Port 0 and...
Hi All,
I have to implement an I2C Slave on my nrf52833 BLE project which is currently working (SDK 2.9.2)
I need some confirmation with the following step:
I have...
I am using the 54l10 chip, and after compiling the project, I will receive a hex firmware and a zip update package. The bin firmware and hex firmware in this update package...
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...
Hello, I need to configure and compile a sample to send an audio stream (mp3) to the I2S interface.
I tried to put together some configuration from other samples but no...

Hi,
I'm really struggling and the Android side (I guess?)
I have a nRF51 app based on the UART initially, with my own services added. etc.
On the Windows MCP it behaves...
Hello,
I work on nrf51822 with S130. I use nus service with uart_c and it's very slow (500 ms to send "abc" test string).
I am not energy limited on this application...
I'm working in a project & I need to update my firmware from my mobile app not through the nordic applications, when I tried nordic applications, just to prove the concept...
It's said that timer0 is used by softdevice and the current consumption differentiates for the defferent timer frequency (PS V3.1 table 22 and table 52).
But I don't find...
Hi,
when using a test based on the UART app, when running it a samsung all is working just great.
However, I tested it on a Nexus 7 with less luck.
From the Sniffer/wireshark...
Can anybody recommend me to select chipset providing following functions?
BLE (Bluetooth smart)
SPI Slave
No need external MCU
UART for debugging (optional...
SWD is supposedly a multi-drop bus.
Is there a way to program multiple nRF chips using only the 2 SWDCLK/SWDIO pins?
How are people programming and verifying boards...
i compiled the ble_uart_exmaple program and it get downloaded to the kit then the four LED on the nrf51DK started blinking continously i dont know what happen to board and...
Hi,
I have a question regarding sending sensor values from a slave to the multi link central. I am using a custom profile on the peripheral to send sensor values as notifications...
I use softdevice s110 7.3.0 and SDK version 7.2.
Some times softdevice call app_error_handler with:

Hi,
I try blinky with softdevice example and reconfigure it to support nRF51822AA. I can program my custom board, I can debug as well, but led is not blinking. I have connected...
Hi,
I want to set the advertising interval to 10.24 sec.
I changed the value of APP_ADV_INTERVAL to 0x4000.
But when i try to discover my device using MCP, it is not...
I'm trying to track down an intermittent bug in programming our Nordic board. So, I'm having to laboriously reconstruct the SWD transactions and understand them.
A transaction...
I use nRF51822 Model in my project that I need to run bluetooth advertising all time. And when I measured current, I found 1mA that is not enough to run for 1 year by just...
