Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
Hello.
I've been trying to use the nRF Beacon for Eddystone app to configure a nRF52 devkit. The idea is to configure a slot as EID and register it to my google account...
Hi there,
I know 3V lithium batteries (Lithium Manganese Dioxide) batteries would be perfect for the nRF51822, but we're wondering if Lithium Thionyl Chloride (Li-SOCl2...
Hello,
is there a softdevice for the nRF52 which supports the proprietary wireless protocoll of the radio nRF24L01+? I only find ones which supports Bluetooth 4.0 and ANT...
Hello,
i have a very small device with bluetooth connection which send data every 20ms to a smartphone. The adc is sampling 100 times per second. Because of the small design...
