ESP8266 SDK with RTOS released on github！

sorry my mistake. it's working. but still freertos sdk is buggy. for example i am trying to connect router in station mode with tcp request but it need restart sometimes.

Could you offer us your test code to replicate it ?

I think I found a bug.
"wifi_get_ip_info" does not work as expected. It returns true without initializing the struct.
This causes dhcp_set_info to fail later on (as it depends on wifi_get_ip_info internally - check "...\third_party\udhcp\files.c" ) and DHCP does not work correctly.

Test code:
{
struct ip_info setinfo;
struct ip_info getinfo;

bool set_result;
bool get_result;

setinfo.gw.addr = ipaddr_addr( "192.168.4.128" );
setinfo.ip.addr = ipaddr_addr( "192.168.4.128" );
setinfo.netmask.addr = ipaddr_addr( "255.255.255.0" );

set_result = wifi_set_ip_info(SOFTAP_IF, &setinfo);

printf("Set returned:%d [IP:%X,GW:%X,MASK:%X]\r\n", set_result, setinfo.ip.addr, setinfo.gw.addr, setinfo.netmask.addr );

get_result = wifi_get_ip_info(SOFTAP_IF, &getinfo);

printf("Get returned:%d [IP:%X,GW:%X,MASK:%X]\r\n", get_result, getinfo.ip.addr, getinfo.gw.addr, getinfo.netmask.addr );
}

Results in:

Set returned:1 [IP:8004A8C0,GW:8004A8C0,MASK:FFFFFF]
Get returned:1 [IP:0,GW:0,MASK:0]

Otherwise, LWIP's BSD sockets seem to work nicely and system is pretty stable if only static memory is used. Using dynamic memory like it's done in the examples (zalloc,free) causes reset at some point.

Edit: It works if DHCP is configured at a later point (other thread in couple of seconds). wifi_get_ip_info then works as expected. I suppose a background thread is responsible for updating the values...

We would like to see new forever deepsleep and deepsleep type functions on freertos. Is it possible? Do you planning to add this features on freertos?
Thank you for your good work.

A few more sockets would be nice. Currently 4 lwip sockets can be allocated.
