I am attempting to generate an 8MHz clock output on pin 2.05. I've followed an example from another post using the nRF54L, but I get build errors. The project I used as a...
Hello,
We struggle to keep LTE-M attached with nRF91 (Modem) and CMW500 (EPS) to test regular IP communication (so those are not Radio Access Network tests) during product...
Hi everyone,
Could someone help me with the following use case?

Hello,
I have made a project that was based on the nRF9151 Development Kit and it works great. I had to select the -ns configuration to get anything to ever build and now...
Hi,
I bought a new nrf52840 DK board as one ofthe original nrf board of my Qorvo QM33120WDK1 kit ( 2 x nrf52840 DK + QM33120W + QM33110W) J3 connector broke. Out of the...
Howdy!
I am attempting to develop a system using an nRF52840 and an ADS131M04EVM (ADC). Our application requires us to collect data at a high sampling rate (>= 16k SPS...

I am trying to use a differential antenna with the NRF51422 and I do not want to misunderstand the datasheet. It says that the optimum differential impedance at 2.4 GHz seen...
If, how can I change the order of the descriptor? I would like to have the user_desc at first.
Most likely by changing their UUID but how to do that? I can't find any trace...
Hi every body,
i try to use 10 bit ADC resolution instead of 8 bit in the ble_uard_adc example, the problem is the ble_nus_send_string is configure to 8 bit, how can i...
Before I order the NRF51-DK I want to make sure, is it possible use it to program other nrf51822 modules? Can I use the Segger on board for flashing firmwares on other modules...
Hello,
Let me first try to describe my whole project I just started with today (Hardware just arrived).
I want to use the nRF51-DK as a central device to handle 4 peripherals...
I have these nrf51822 modules, bought them from this company Wireless Tag , it's a chinese company I guess but I just noticed that the modules only have a single 16 MHZ oscillator...

I'm working with the ble_app_hrs_s110_with_dfu_pca10028 (nRF51 PCA10028) example and am wondering what will happen if I attempt to send more than one sample at a time. Will...
It looks like APP_TIMER_INIT changed in v8 of the SDK. I do NOT want to run the code for timer callbacks in the IRQ, I want to run in the background loop. How should I properly...
Hello,
Our application board uses two NRF24L01P and two microcontrollers, so we have total four quartz generators on board. To simplify things we would like to use a single...
I have a project which measures temperature and humidity. After measurement the data should be send trough BLE.
I have one service for the sensor and two characteristics...
Hello,
what do I need to pay attention to calculate the consumption of nrf51822 in low power mode (sleep).
I make this simple program :
