[lwip-users] ERR_ABRT: Out of pcbs or netconns

Hi all, I am developing a MODBUS Server which can serve multiple clients simultaneously, using LwIP 2.0.3 & netconn and FreeRTOS 9.0.0 and STM32H743BI. A client (my pc in this case) can connect the server with no problem. When disconnected and connected again there is no problem also, but if it

Kanka ben uzman değilim LwIP konusunda. STM32H743 için CubeH7 örneklerinden yola çıkarak iskeleti oluşturmaya çalışıyorum. Söylediklerinin üzerine kodu şu şekilde değiştirdim: Bu şekilde hiç başarılı bağlantı kuramadım. Teşekkürler. -- Sent from:

Re: [lwip-users] Netconn API Server Mode Connection Drope Detection

netconn_receive must return ERR_CLSD when connection closed. Check your error code in every loop. -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html ___ lwip-users mailing list lwip-users@nongnu.org

Hi Ricardo, ricardoschoof wrote > Please read for more information about the API's: > https://www.nongnu.org/lwip/2_0_x/raw_api.html I have read that doc. Point is I have a TCP server also written using RAW API, and it works fine. I have tried to write this server with netconn but failed. But

Original code is: And a part of lwipopts.h: But sarp corrected me and it turns to: But when the second code is active, there is 1 OK and after 1 ERROR message from modbus client program in PC. After some communications (generally after 3 OK messages) no more tx or rx. Thanks. -- Sent
