BLE Write Commands (Write Without Response)
<p>In the Bluetooth 4.0-4.2 Specifications Vol 3 Part F, I can find this text:</p>

<blockquote>
  <p>Commands and notifications that are received but cannot be processed, due to
  buffer overflows or other reasons, shall be discarded. Therefore, those PDUs
  must be considered to be unreliable.</p>
</blockquote>

<p>I wonder, who receives? For Write Commands, is it the ATT server that receives from the ATT client, or might it also be the ATT layer of the sender host that receives a request to send a Write Command from the client app that drops the Write Command, i.e. it gets dropped before even being sent out over the air?</p>
