Detailed Description

Arduino Stream interface for IEEE 802.15.4 transceiver.

Allows using ESP32TransceiverIEEE802_15_4 as a Stream for easy integration with Arduino APIs and libraries that expect a Stream object. Provides buffered read/write access to the transceiver.

If you want to control the creation of the individual frame segments, write data smaller than the MTU (127 bytes) and call flush() to send the frame immediately.

When you write data to the stream, that is bigger than the MTU, it is automatically split into multiple frames and sent one after another.

When you enable acknowledgment requests for outgoing frames, the stream will wait for the acknowledgment frame from the receiver before sending the next frame. If the acknowledgment is not received within the configured timeout, the stream will retry sending the frame after a delay. This process will repeat until the frame is acknowledged or a maximum number of retries is reached.
