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

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.

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...

Did you set softap_config.ssid_len ?

It is the same as non_RTOS_sdk http://bbs.espressif.com/viewtopic.php?f=5&t=53

ok. It seems working now. but i tried set ssid and it's working too except one thing. What is ssid size? i saw ssid:uint8[32]. i set ssid to "espTestWifi2" and
i saw "espTestWif" in wireless networks. than i set ssid to "esptestwf" and i saw "estestwf" in wireless network. it seems code working fine but ssid name accept just first 9 char.

Sorry for this issue, memory for user_init is too small.
Please unzip the attachment, replace libmain.a and try it again.
