Multiple Clients Teensy41 server example QNEthernet #65

videojedi commented 1 year ago

HI, When trying to run the following example, my teensy seems to get stuck in a loop of accepting new websocket client connections. I don't quite understand what is happening. I'm using the latest build of QNEthernet. Doesn't seem to happen with Native Ethernet. Possibly didn't happen on versions prior to latest release?

https://github.com/khoih-prog/WebSockets2_Generic/blob/master/examples/Generic/Teensy41_QNEthernet/MultipleClients_Teensy41_Server/MultipleClients_Teensy41_Server.ino

Terminal output is

Accepted new websockets client at index 0 Accepted new websockets client at index 0 Accepted new websockets client at index 0 Accepted new websockets client at index 0 Accepted new websockets client at index 0 Accepted new websockets client at index 0 ...

Arduino IDE version: 1.8.19 Teensy4.1 QNEthernet 0.17.0 Windows 10

Many thanks Richard.

Hi @videojedi

Just comment out the unnecessary line

https://github.com/khoih-prog/WebSockets2_Generic/blob/3dd5c9f98470b1a0e445c62a3535934e83aec72d/examples/Generic/Teensy41_QNEthernet/MultipleClients_Teensy41_Server/MultipleClients_Teensy41_Server.ino#L253

Be sure to have the client connect to the same IP:port
