Crash after start paring #1

Open Alynva opened 7 months ago

Alynva commented 7 months ago

While running the examples, whenever I try to pair with my phone the program crashes with this error:

bleno - echo

  const output = Buffer.alloc(input.length);

Node.js v18.13.0

It appears that its receiving SMP_PAIRING_RANDOM before SMP_PAIRING_CONFIRM, so this._tk doesn't have a value yet... Any clues?

Sorry for late reply. Can you provide some more details about setup yyou had. Hardware platform. Which BLE HCI?/Windows? etc.
