packets

 When Data Is Written to Module’s UART, TCP Packets

Forwarded Based On

 Flush timer

 Flush size

 Match character

 TCP Packet Sent When Any of These Events Occur

 Parameters Logically ORed to Determine when TCP Packet Is Sent

 When Configured Correctly, Module Can Be Optimized for Low Latency or High

Throughput

 Low latency: use lower flush timer value & flush size

 High throughput: use higher flush timer value & flush size

Tip: Module Tries to Optimize Automatically for Bandwidth

by Increasing Default Flush Size with Higher Baud Rates
