Hi,
I am working on my hardware product having nRF-51422 chipset. I just came to know from forum post that
nRF-52 chips will get arduino IDE support as standalone. I want...
Hi!
I've been using PCA10028 for a long time and I had some bricking issues but I've managed to un-brick it with "nrfjprog --recover" and everything would work again. ...
I am struggling to configure all of the options I desire to on the the "ATT-MTU Throughput Example". This is the version provided in the v15.0 of the SDK, with the hex file...
Hi,
I have two nrf52dk devices.
I Want to test the BLE examples which can exchange Bytes of information between each other and display over the UART.
Which examples...
Hi.
My target board has a power switch that is managed by GPIO.
First-time, a user clicks the button, the GPIO is turned on and the system wakes up.
In reset case(Firmware...
I'm troubleshooting my NFCT state machine -- I'm getting a lot of FRAMEDELAYTIMEOUT errors and can't understand why, I'm triggering a TXSTART ASAP... but that's another issue...
Hi there,
Is it possible to feed XC1 or XC2 with an oscillator output rather than using a crystal?
It would make sense for me in terms of application but I cannot see...
hello , I followed this tutorial : devzone.nordicsemi.com/.../wireless-timer-synchronization-among-nrf5-devices

Hi there,
I was wondering if there was an easy way to output the LFCLK from our 32k crystal on one of the GPIO pins of the NRF52840?
Couldnt find anything in the Spec...

At this moment the 4 peripherals send their data to the central without problem one after the other...
Hi
I have RGB LED Strip of 5 numbers and giving out 5V from external power supply
This LED Strip has WS2811 as LED Driver ( https://cdn-shop.adafruit.com/datasheets/WS2811...
Dear all,
It's strange that this seems to not have been asked before... since the nRF52840 can be powered directly from a LiPo battery, I wonder if there is an UVLO protection...
Dears,
I am developing a board based on the nRF52-DK board and I noticed the technical documentation does not include the voltage ratings of the capacitors used. Could...
I am trying to make a large BLE sensor network, hypothetically anywhere from 20-100 devices in a STAR configuration. I see there is a 20 max limit on concurrent connections...
