Re: [lwip-users] Network Loss causes network to go down
Hello all, My project environment is: - Controller: STM32F439BGT6 - Ethernet PHY chip: LAN8742A (from Microchip) - OS: FreeRTOS - TCP/IP stack: LwIP Version 2.0.3 My project also requires to identify Link (network) disconnection. I used HAL_ETH_ReadPHYRegister (, PHY_BSR, ) to identify the status of the link. The definition PHY_LINKED_STATUS masks the bit of link status. I read the PHY register twice to ensure the link is down. I changed the function ethernetif_set_link() in the file: ethernetif.c for reading twice the PHY register. The link disconnection is identified successfully.

Its a fundamental thing with TCP and UDP that there is not way to know, that the link is valid but the other side just did not had anything to say unless you added it to your protocol. Using cable detection in the phy might help, but only a little bit as most devices talk to other devices that are multiple hops away and any problem between the first hop and the remote side are not covered then. I once had a project where a LWIP driven device had to send small amount of data ever few minutes to a remote server that was located on the other side of the world. This devices had nobody to maintain it like watching for status leds or pressing a reset knob. We finally solved the issue using multiple points: - enabled timeouts for receive and transmit to never block. Thats what we observed first: the transmit loop was blocked due to to many unacked data. - use some watchdog/ping command in the protocol to detect if the connection to the remote side is still valid/active. Thats the only way to be sure, the remote side is still reachable. The F427 has lots of RAM. You might provide more storage to allow more then one connection.
