Re: [lwip-users] help with mDNS sending a DNS_RRTYPE_SRV query

Hi Erik, I am using a simulation like environment, and since I am using a loopback interface, and I am unable to see TX/RX packets through wireshark on the *loopback_if *127.0.0.1. However, I added my own hack functionality *err_t mdns_resolve(const char* hostname, ip_addr_t *addr,

[lwip-users] TCP Dup ACKs and TCP Window full

I took some steps to see if the packet loss problem can be solved: - Migrated to ChibiOS 18.2 with Lwip 2.0.3 - Used only internal ram of STM32 instead of SDRAM Firstly, jumping to Lwip 2.0.3 made no difference at all. I think, this problem is not caused by Lwip itself

Ok, I do not usually take captures, so I did not know I can shorten them. I will try next time. I will check memory settings and reevaluate if there are errors. Adrian Von: lwip-users Im Auftrag von goldsi...@gmx.de Gesendet:

Hi Antonio, didn't you already figure out a couple of mails back that the problem is that your stack is too small so you get a stack overflow in mdns_readname? The recursive function has a max depth check so you shouldn't be in an infinite recursive loop. BR /Jens On 2018-04-10 14:14,
