Basic Infos

I found the esp wifi doesn't connect to an ssid if it is hidden. I connect my devices just fine to the ssid while unhidden, most wifi devices should reconnect just fine once the ssid is known and then is set to hidden. I even went in to the esp and set the ssid and pw by hand, but it still doesnt connect. Setting ssid back to un-hidden, they connect right up.

Im using a mikrotik RB751 for an access point with the latest firmware 6.36, WPA2-PSK and 2.4 n-only mode.

im using wifimanager lib in case that has any bearing.

I found that Mikrotik's n-only mode was the cause of this, the esp connects just fine to hidden ssid when the AP is set to b/g/n mode.
