waiting time for packet transmission will be adjusted fast and slow.
Distance: When the "Distance" button is clicked, the point-to-point bridge distance can be
entered. The system will automatically calculate the ideal reference value for the Slot Time and
ACK Timeout. The input distance is calculated in units (meters).
ACK Timout : When waiting for the "ACKnowledgment frame" interval is too long to be received,

the ACK will be retransmitted. A higher ACK Timeout will reduce packet loss, but the
transmission efficiency will be poor.
Setting Slot Time and ACK Timeout can strengthen the long-distance
connection. Changing the value can optimize the setting. If the value is too
low, the length transmission will be reduced. If the value is too high, there may
be disconnection.
