If we want the RCU stay awake all the time when BLE is connected with a host, would it cause the possibility of random BLE disconnection?
Is this all...
Hi,
I want to implement SWD (and potentially UART lines) over a type A to C USB cable to talk to the NRF52832 on our board.
Currently, we only want to sink power only...
I am really green, so please bear with me. I have been experimenting with the bicycle ANT+ examples in the nrf52-dk API, and have been able to get BSC working to point of...
