3.5 WAKE# Signal

WAKE# pin (the signal that the module uses to wake up the PC) supports software control.

This signal is used for module to wake up the host. It is designed as an OC gate, so it should be pulled up by the host and it is active-low.

When the module wakes up the host, the BB Chip hold 1s high-level-voltage pulse and then module output low-level-voltage to wake the host.

3.6 RESIN_N Signal

The RESIN_N pin is used to reset the module's system. When the module software stops responding, the RESIN_N pin can be pulled down to reset the module hardware.

The RESIN_N signal is internally pulled up to 1.8 V, which is automatically on when 3.3 V is applied and it is active-low.
