Hi Vincent, my application is not time critical and due to an error on the PCB the interrupt line from my ethernet controller is not connected.
Right now my sollution works like this: my driver is initied via *_init() and creates the task that periodically polls my ethernet controller for new frames and events. When cable plug/unplug occurs a function is called (this function is registred as a callback to keep the project structure sane). This function then safely executes netif_set_link_up/down(). The task polling the ethernet controller is run every ~44 ms. I'm not sure what sort of response time you are hoping to achieve but for my purposes it seem to work fine. /Åke ----------------------------- Åke Forslund 0433-273296 NIBE AB Box 14 S-285 21 Markaryd Tel +46-(0)433-273296 From: vincent cui <vincent....@enlogic.com> To: Mailing list for lwIP users <lwip-users@nongnu.org> Date: 2011-09-07 01:15 Subject: Re: [lwip-users] how lwip know internet cable is unplug Sent by: lwip-users-bounces+ake.forslund=nibe...@nongnu.org >>>> My approach is to send a signal to a separate task to handle the cable-plug/unplug events Ake: For your approach, who send a signal to the task ? the driver ? my driver can get the link status by polling, not interrupt, so it takes more cpu time..I stop using it And try to find another one to replace… maybe it need HW sensor support.

I think that is something you define in your ethernet driver. My approach is to send a signal to a separate task to handle the cable-plug/unplug events. In the task I currently disable dhcp (if active) on cable-unplug signal and reenable it on cable-connect. it might be good to set an auto-ip when unplugged as well, but I'm not sure. Maybe it should be handled with the netif_set_up/down-functions instead, I'm still experimenting... /Åke ----------------------------- Åke Forslund 0433-273296 NIBE AB Box 14 S-285 21 Markaryd Tel +46-(0)433-273296 From: vincent cui <vincent....@enlogic.com> To: Mailing list for lwIP users <lwip-users@nongnu.org> Date: 2011-09-02 07:27 Subject: [lwip-users] how lwip know internet cable is unplug Sent by: lwip-users-bounces+ake.forslund=nibe...@nongnu.org Hi; When unplug internet cable, how lwip deal it ?

No, I'm not sure why you need any of your sockets to be non-blocking.
