This PR contains several corrections needed for HCI to work correctly on both ninafw and cyw43439:

  • separate read and write buffers to accomodate read buffer with pending partial data to be handled
  • only read when there is data pending to avoid putting cwy43439 into forever loop
  • handle any data in buffer from read that contains data from more than 1 packet
  • skip past data for sync packets since we do not handle them anyhow
  • some better naming and comments to hopefully clarify a bit what is going on

Addresses #300

Thanks! Examples work on the Nano 33 IoT with these changes.

Thanks so much for this fix! I was unable to enable the bluetooth adapter on my Arduino Nano 33 IoT. But after updating to your commit in my go.mod, it works! Now I'm unblocked!
