Hello Strafe and all,
Were you successful in getting the K83 paired to the Raspberry Pi? I am currently having the same trouble and would love some assistance if possible. I am using a Raspberry Pi 3 B+.
When I try to pair, I get no prompt giving me a security pin to enter on the keyboard and the BT on the Pi crashes, forcing me to reboot the Pi if I want to try again.
Thank you in advance for any suggestions.
