Hi,
We have built a BLE product using nordic nrf51422. When system power off mode is enabled, the current consumption is coming to be around 16 uA. In our application,...
Dear Nordic Team,
Thanks for support.
I want to know the possible for voice file transfer to over BLE. I am using BR281 audio detection on semiconductor. I want do the...
I'd like to retain a few bytes after a restart from system_off. I know the GPIO state is retained, are there any other registers other than that? It looks like RTC1->CC[0...
I've been struggling for some time to get L2CAP transfer between an NRF51822 and a Linux machine using bluez.
I've successfully created a connection between the central...
Hi,
I want to understand ANT and want to begin development with ANT once I figured out how it works. After reading posts on this forum I found out that not all Softdevice...
