[lwip-users] Closing netconn, application or lwip bug?

Hi, I am developing a commercial application for embedded device using lwip. My device is listening on specific tcp port for incomming message, if client connects can send request and get response then decide if want to keep connection or disconnect. My device is based on AVR32 processor, and

Re: [lwip-users] Closing netconn, application or lwip bug?

Hi, Thank you for answer, this code was only a simplified example of my code, there are some synchronisation mechanisms used in application, I removed them to clarify my question. I will recheck them again. My message was only part of description of my problem, read full story in another email. --

[lwip-users] Sending out small TCP data very fast

Hi everyone, I'm using lwIP v1.31 with an 72MHz Cortex M3 Processor and 64kB RAM. I need to write small 10-35bit messages as fast as possible through ethernet. I've set up a timer to 50ms, the timer interrupt executes a tcp_write and a tcp_output. My problem is that every outgoing Message, when

[lwip-users] coap on lwip

hello lwip-users, have you hever heard of or seen an implementation of coap (constrained application protocol[1]) atop native lwip? everything i've seen so far is based on contiki/uip, but i'd need coap and serious tcp inside the same device. as a warning to whoever wants to look for such

Re: [lwip-users] coap on lwip

I have just been doing the same search - and evaluating coap as an option in one of our projects. On Mon, Jan 14, 2013 at 9:18 AM, chrysn chr...@fsfe.org wrote: hello lwip-users, have you hever heard of or seen an implementation of coap (constrained application protocol[1]) atop native

Re: [lwip-users] coap on lwip

I had given libcoap a quick look over the weekend! It seemed like the best choice as a starting place. My biggest concern was I need an lwip raw API implementation, and a minimal memory footprint version. I'd be happy to help - tell me what you need from me. Feel free to email directly:
