Hi everyone,
I'm working on a project using the Nordic nRF5340 microcontroller and I need to count both rising and falling edges of a square wave signal on pin P0. 14, coming...
Hello, I’m working with a combination of nRF5340 + nRF7002 + NPM1300 , and I’ve only changed the I2C pins connected to the NPM1300 to sda pgio1.4 and scl gpio1.6 .

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...
In the download section, all other SoftDevice versions are named "(Production ready)". Just the new S120 v2.0.0 is not. Does it offer the same stability/reliability as the...
We have an nRF51822-based product that goes the SYSTEM OFF in certain situations.
We wake up with the DETECT signal from a pin which we set to sensing just before calling...
I want to have it wireless capabilities into the cable, the receiver and transmitter antenna ports with shielded wire connected directly, so there will be a wireless signal...
Hello! I want to broadcast messages between 2/3/4/5/... devices. How Can I broadcasts between devices? Each device must receive messages from others and also broadcasts to...
Hi,
I'm unable to configure the UART so, that it will generate the TXDRDY event. I have an UART that should send periodicaly 4 Byte sequences without hardware handshake...
Hi,
For my research project on novel antennas I need a demonstration prototype, and the nRF51822 Beacon Kit would be ideal for me (due to its small size and battery power...
Hi there,
I was wondering it it is possible to use MATLAB as a central device, using a third party dongle?
The MATLAB Instrumentation Contol Toolbox can be used to control...
Bluetooth v4.2 included an ability for attributes to be greater than 20 bytes of payload data long. Is there anything in the nrf51822 hardware that would prevent this from...
Hi,
Does anyone know the maximum baud rate of the nrf24l01+? I am trying to talk to it through SPI but observe that when I increase SPI speed I read incorrect values. Does...
Recently I was attempting to use the nrf51822 SDK's app_uart module's APP_UART_FLOW_CONTROL_LOW_POWER mode (currently using APP_UART_FLOW_CONTROL_ENABLED ). I noticed that...
Hello,
I would like to send some data i read over I2C. But the I2C and BLE Stack should not run at once, is it possible to check the state of the BLE stack?
The core specification v4.0 vol 3 part C section 3.2.2.3 "Bluetooth Device Name -- Representation" states that the device name can be up to 248 bytes. I've confirmed that...
Dears:
I know there are three modes as below :
(1) internal LDO regulator
(2) 1.8 V low voltage mode
(3) internal DC/DC converter
So, I have some questions as below...
Hi, we are trying to calculate operational current. Does anyone know what the test voltage is in nRF51422_PS v3.1. I assume for typical it's 3.0V and Max is 3.6V?
Also is...
