I would like to ask you about latency of TCP connection. To be more specific. My proposed network should consist of one module in AP mode and several (lets say max. 20+) of slave modules. These modules should be in the network under that AP. Proposed modules are WizFi-250s.
Once upon a time the master node in AP sends UDP broadcast to synchronize time inside slave nodes (I suppose it is OK, because I need tolerancy of +/-10ms)
But to the crucial thing:
All slaves will be in TCP listening state in the meantime. What is the best estimation of TCP connect latency from master node to the listening slave node? In other words time from AT+CONNECT or sth. to successfully established connection ready for data exchange. I need this time just to check if whole round-robin of slave will be enough short to preserve buffered data in slave nodes.
Many thanks for your answer,
