Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi,
I'm running a GPIOTE test that pulses a debug pin whenever CPU executes user registered GPIOTE handler. The GPIOTE trigger pin has a 8ms period, 8us duration low-active...
Hi
I used SDK v5.2, SD : s310 v1.0.0 and nRF51422 v2 (QFAA E0).
The power consumption is too high when I used GPIOTE to do interrupt.
Disable GPIOTE:
The current...

I would like to store some configuration data on non-volatile memory in nrf51822.
I'm using pstorage library to access flash, but I have problem with api calls. What I am...
Hi,
I'm developing custom PCB with nrf51822 (low voltage mode) and I have troubles with flashing the chip. I cannot see the chip in nRFgo Studio. I can flash original devboards...
Dear SOC developpers,
As many kickstarters i bought an RFDUINO kit, then I made a cool prototype thanks to the easy Arduino compatibility. I'm now thinking of industrializing...
Is there a simple software code example how to configure an interrupt handler for a single GPIO-pin? I am using nRF51822 chip with softdevice S110 and the interrupt source...
My question a little weird. Because I am super beginner about BLE. So what I want is how to write string data. now i am looking to information about this. I cannot find it...
Hi
I'm trying to implement bonding in a device based on the S120. As counter part i've used a S110 device or an iOS device (realized with LightBlue App).
While searching...
Hi All,
I am using nRF51422 and now doing ANT+ certification test with tool v1.3.6. And i find out some problem with the received value on my display in case of following...
