+ * FORCE-ON (only SE868-A)
+Force-ON is an input signal that can be used to wake up the SE868-A from the sleep mode. 
+It is internally pulled-up. It has active-low logic, i.e. the module wakes up when FORCE_ON is tied to ground. When inactive, it should be left open drain or open collector.
+
+Note:
+keeping FORCE_ON tied to ground won�t prevent the SE868-A from going into sleep mode, since this signal is sensitive only to the high-low transition.
+No pull-up circuits are allowed on the FORCE_ON pin, since the signal is already internally pulled up.
