... Inputs must not exceed 1.2 V. The sensitivity saturates at 400 mV. Ad Hoc Mode & Restoring Factory Settings Ad hoc mode is controlled with GPIO9 (pin 24). Roving Networks recommends that you connect pin switch or jumper connected to a pull up. When GPIO9 is driven high at power up, the module enters ad hoc mode. If GPIO9 is then toggled low 5 times, the module will be restored to it’ ...
