I use P0.2 as a wake-up pin, when the system into a deep sleep, I connected a High Voltage in the P0.2, it can wake up, but if I connected a High Voltage in the P0.2 always...
Hi
I got some questions about the RF part of the ref schematic.
1, why the bias voltage for ANT1 anf ANT2 are not the same since they are differential lines?
2, what...
Hi,
Today I use the app timer to start a simple 8bit ADC conversion each second and send in the irq handler.
Now I am trying to use the sw interrupt to execute some...

Hi,
I ran the Nordic nrftoolbox on Sony Z1 android 4.3. I found that the device name is not showing on the list as attached. Running the Nordic nrftoolbox on Samsung S4...
Hi there,
We are using the nrf8001 and a arduino to read out two sensors.
The two measurements should be at the same time and therefore are coupled to eachother.
Is there...
