Hello.

I can’t turn on the AP mode in security mode  
An error occured when I am running example  
(Open the WiFi AP example, “File” → “Examples” → “WiFi” → “WiFiAPMode”)

- Platform : Arduino
- Power : USB
- Amebad : 3.1.6

char ssid[] = "2203KR0202-0039"; char pass[] = "xxxxxxxxxx"; char channel[] = "1"; 1. Security mode : WiFi.apbegin(ssid, pass, channel, ssid\_status); \<-- got the error 2. Open Mode : WiFi.apbegin(ssid, channel); \<-- work well

if anyone have solution to my problem it’d be really helpful…
