I am analyzing the power consumption of a custom board with an nRF52833 BLE SOC and nRF21540 FEM for different BLE parameters. In one of my experiments I vary the amounts...
Is there a straightforward way to output the frequency of the 32.768kHz crystal oscillator to a GPIO pin? The motive for this request is to verify the crystal frequency without...
Hello,
I'm developing for nRF54L15 the application with the NSIB + MCUBoot. I have a problem with fprotect in mcuboot returning EINVAL error. That happens due to limitation...
Hi all,
do different settings of SAADC RESOLUTION register affect Conversion Time t CONV ? I cannot find any dependency - the only value given for t CONV is 2 µs typ (7...
My product has nrf52840 with usb mass storage configured using 8MB QSPI flash (same chip as the nrf52840dk - MX25R64)
I would like to allow users to upgrade firmware by...
I will attach my main.c and skd_conifg, maybe i'm overseeing something in code. Also i will attach schematics and pcb. I'm aware of RGB led consumption, in reality it's around...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
Is it the only way to call a function on a read characteristic to make a read request and then inside on_ble_event call the function?
Is this the right way?
Hi
in the communication with an SPI peripheral device, a communication cycle might take up to 5 ms.
It is implemented as a blocking function, meaning that app_sched_execute...
Hi all! Several weeks I've tryed to implement code for my wireless temperature sensor based on nrf24le1 and ds18b20. In datasheet said that in memory retention mode the power...
Hi,
Is it possible to send a advertisements for a single (or a fixed number of) Advertising Events? I need to control the number of Advertising Events "sent" for a mesh...
Hi, I'm looking to build a simple ANT+ application. My only asset for this project is a background in C/C++. I'll need to learn/relearn the basic electronics and protocol...
Hi Nordic,
I have an application that perfectly runs in the nrf51DK but that does not work in my custom board. In my custom board everything else works (i2c, leds lighting...
I understand that in order to trigger bonding procedure you need to read/write a secure characteristic.
I am using the nRF Connect application on IPhone and trying to see...
Hi all,
I need to take samples of a period of two periodic signals and made some DSP processing with both signals.
I need at least 64 to 128 samples per signals.
I...
Greetings,
In Bluetooth 5, there is a new mode of advertisement called periodic advertisements where the advertising device can periodically advertise over the 37 non-primary...
I have a design running on nRF51 that I'm evaluating to run on nRF52. One important characteristic I'm looking for is to store it for long period with a minimum power consumption...
Having some problems upgrading the PCA10056 to firmware 1.0.1 as stated in the getting started. After downloading the only file I found I can no longer connect to it.
Can...
I've been trying to use nRF52 (PCA10040 board) with SDK 12 to read data from max30102 through I2C.
I used non-blocking read and this is twi init function and event hander...
According to S130_SDS_v2.0, I can choose to return NRF_RADIO_SIGNAL_CALLBACK_ACTION_NONE after NRF_RADIO_CALLBACK_SIGNAL_TYPE_EXTEND_SUCCEEDED to stop extend more timeslots...
I want to trigger SAADC by PPI between RTC compare event and SAADC sample task. Is it possible?
In the SAADC example (SDK 12.2.0), a timer is implemented. In function nrf_drv_timer_extended_compare...
