Hi Kiran,

posts like this, which basically say "I seem to have some arbitrary problem, I use 10 other libraries and lwIP, please help me!" normally don't get much attention here. Everyone reading and writing here does this without getting paid for it (and your mail + address suggests you use lwIP for a product you get paid for). We might be able to help you, but only if you are willing to do the work and ask for guidance, not ask us to work for you (without getting paid).

In other words: try to debug, try to locate the fault, ask us if this and that could be the problem, etc. With a more details bug report or failure question, you might get more answers.

With the mail like this, I just say: lwIP is fine, check why your driver drops frames (which makes select time out).

Cheers,
Simon

Hi all,

 

We have been using the lwip on the LPC1769 platform along with the wolfSSL, wolfmqtt libraries. We have a rabbitmq server to which we are communicating from this LPC client. Our problem is, some times the communication succeeds but sometimes it fails, in fact the lwip_select times out. Not sure why, I anyone of you can help us any where it will be very helpful. I am attaching a detailed log we captured from the LPC client and the ‘lwipopts.h’ file we use on the LPC herewith.

 

Kindly help out.

 

Regards

Kiran
