Hello,

I'm running the latest version of the bleno package and when I'm trying to swtich from a paried phone to another phone i get this error:

/home/pi/NodeBLETest/node_modules/@abandonware/bleno/lib/hci-socket/crypto.js:60 var output = new Buffer(input.length); ^

Is there a way to bypass the pairing itself or the code that causes this issue?

The code runs on an RPi 4

Thanks!
