25. to sleep In UDP protocol mode the auto conn timer is re defined as an auto sleep timer Upon the start of transmission of the first UDP data packet this timer will count down set sys autosleep value UDP mode sets the auto sleep timer 0 disables the timer is decremented every 10 milliseconds Because the timer is asynchronous the actual value can vary by 10ms Using a minimum value of 2 is recommended to ensure that the UDP packet gets transmitted For larger packets the value should be increased In TCP Client mode the auto conn timer is used as a connect out timer If set the device will automatically attempt a connection when the timer expires set sys autoconn secs In TCP Client AND TCP Server mode there is also a disconnect timer set comm idle secs sets the idle disconnect timer This causes a disconnect if no transmit or receive data is seen 5 1 Wake on Sensor INPUTs There are 4 inputs available to wake the module from sleep SENSI 4 To enable 1 of these inputs use set sys trigger lt 0 1 2 3 4 gt 0 disables Only the SENSI input has a resistor divider 24K in series with 10K to GROUND which allows this pin to tolerate 3V logic The other sensor pins DO NOT so care must be taken WARNING Under no conditions should the voltage on any SENS2 8 input exceed 1 2VDC Permanent damage to the module will result The SENS1 4 inputs have a small current source that is activated in sleep mode This source is app
