Working Mode

STA / AP / STA + AP three operating modes.
  • ♦ STA mode: modules are connected via a router Internet, mobile phone or computer via the Internet to the device's remote control.
  • ♦ AP mode: module as a hot spot, to achieve mobile phone or computer directly communicating with wireless control for LAN.
  • ♦ STA + AP mode: two modes of coexistence mode, which can be controlled via the Internet can seamlessly switch for easy operation.
