Exactly. Concurrent operation is no problem in lwip. Closing this as invalid. Please write to the lists of you have questions about the usage of lwip.

Are you using threads or RTOS?

Are you calling any lwip api from i interrupts?

By experience, the tcp raw api is where it is easiest to do small mistakes that can cause crash or lockups later. Try to minimize your code to a working crashing one and ask help at the users mailinglist

Yes, of course concurrent operation is supported! I assume there's something wrong in the way you are using lwip.

[field #13]                  Summary: LWIP UDP and TCP Concurrent Operation

[field #14]      Original Submission: I am using LWIP in a TI TM4C129X MCU application that sends UDP packets every 10ms and receives TCP packets that contain configuration settings for out hardware.  I can send UDP packets without a problem and I can receive/send TCP packets but when I try to do both I eventually get a stack overflow.  Can LWIP handle UDP and TCP concurrently?
