I wonder if this keyboard is timeing out while I am walking the 50 feet from turning it on, back to this ssh console to type show. Would it be that fast?

In which case, can bluetoothctl trigger that wakeup? > On 9/26/20, Gene Heskett <ghesk...@shentel.net> wrote: > > On Saturday 26 September 2020 06:48:11 Alan Corey wrote: > >> Bring your devices closer together at least until you get them > >> paired.
