//|
//| Accumulates a Characteristic's incoming packets in a FIFO buffer and facilitates packet aware

//| unit (MTU), whichever is smaller. The MTU can change so check `packet_size` before creating a

//|
//| When we're the server, we ignore all connections besides the first to subscribe to

//|
//| .. class:: PacketBuffer(characteristic, *, buffer_size)
//|
//| Monitor the given Characteristic. Each time a new value is written to the Characteristic
//| add the newly-written bytes to a FIFO buffer.
//|
//| :param Characteristic characteristic: The Characteristic to monitor.
//| It may be a local Characteristic provided by a Peripheral Service, or a remote Characteristic
//| in a remote Service that a Central has connected to.
//| :param int buffer_size: Size of ring buffer (in packets of the Characteristic's maximum
//| length) that stores incoming packets coming from the peer.
