10.2.1. LED INTERFACE
The Wireless Module will provide two control signals to the host and capable to drive an LED
to indicate the connectivity and operating status.
The WM-BG-MR -01 have 2 LED’s (output) via 60 pins connector for feedback to the user on
the current WLAN activity state. The signaling will reflect status / activity as described in the
table below. Those two signals are provided via the board to board connector with the
following pin assignment.
