One instruction missing from your example to enable wifi connection

[spinoza1791]

One instruction missing. Here is the default line from example face recognition:

uint8_t wifi_mode = 0; //1:station mode, 0:access point mode

In your instructions, make sure to ask user to change mode to 1, like this:

uint8_t wifi_mode = 1; //1:station mode, 0:access point mode
