wifi_softap_set_dhcps_lease函数错误

[zhongjru]

设置softAP模式，启动DHCP服务错误（wifi_softap_set_dhcps_lease函数返回false），代码如下：
int ap_setup(void)
{
struct ip_info info;
struct softap_config config;
struct dhcps_lease dhcp_lease;

if (!wifi_set_opmode_current(SOFTAP_MODE)) return -1; //Set softAP mode

strcpy(config.ssid, "configmode");
strcpy(config.password, "12345678");
config.ssid_len=strlen(config.ssid);
config.channel=11;
config.authmode=AUTH_WPA2_PSK;
config.ssid_hidden=0;
config.max_connection=4; //max 4
config.beacon_interval=100;
if (!wifi_softap_set_config_current(&config)) return -2;

wifi_softap_dhcps_stop();

IP4_ADDR(&info.ip, 192, 168, 1, 1);
IP4_ADDR(&info.gw, 192, 168, 1, 1);
IP4_ADDR(&info.netmask, 255, 255, 255, 0);
if (!wifi_set_ip_info(SOFTAP_IF, &info)) return -4;

const char* start_ip = "192.168.1.2";
const char* end_ip = "192.168.1.102";
dhcp_lease.start_ip.addr = ipaddr_addr(start_ip);
dhcp_lease.end_ip.addr = ipaddr_addr(end_ip);
if (!wifi_softap_set_dhcps_lease(&dhcp_lease)) os_printf("wifi_softap_set_dhcps_lease fail\n"); //return -3;

if (!wifi_softap_dhcps_start()) return -5;

wifi_status_led_install(13, PERIPHS_IO_MUX_MTCK_U, FUNC_GPIO13); //GPIO13 is status of WIFI

return 0; //success
}
忽略错误继续运行，功能无误，原因？

您好，

我试了您的代码，运行正常。

请问您使用的 SDK 版本号是多少？能否提供完整的运行 log 以供分析。

最新SDKV1.4，硬件是ESP-12E

您好，

我试了您的代码，因为没有 gpio.h ，测试时将 GPIO 和 UART 部分去掉了。
测试未能复现到您的问题。

附件为我编译生成的 bin 文件，麻烦使用测试，看是否有问题？
