HF-LPX70 Series Wi-Fi&BLE User Manual 1. At wireless firmware and config upgrade mode , this LED used to indicate configure and upgrade status. 2. At “SmartLink” config mode, this LED isused to indicate APP to finish setting. 3. At normal mode, it’s Wi-Fi link status indicator.Output Low when STA mode connect to router AP or other STA connect to it when in AP mode. High-Flying strongly suggest customer fan out this pin to LED. UART1 Debug ： 1. 1.2.2.
