I am using the BF607, uC/OS-III, lwIP. I changed the "Number of Connections" in the lwIP Library Configuration and as expected more devices can be connect as one time. The product application may have many more devices than I currently have available to test with. I tested with about 15 devices. Each device sends just a handful of bytes across the connection every few seconds but they stay connected always.
I can set the max to as large of a number as I like but would like to know what the true limit is without buying hundreds of physical devices to test with. Trying to estimate based on available memory and CPU utilization yields ridiculously high results.
Has anyone tried many connections with this OS/processor/stack combination? Perhaps 50 or even 100 simultaneous connections is my goal.
