3.Saving power model
HXJZ-873 have three Saving power models: awaken from Hardware, awaken from COM Port, awaken from
Air. The model can be set by RF Module software. You can choose one saving power model, the default
model is awaken from Hardware.
1) Awaken from Hardware:
When HXJZ-873 sleeping in this saving power model, the current is under 100uA.
Sleeping status: when you input low level at NO. 5 pin, HXJZ-873 can sleep. In this status, HXJZ-873 cannot
transmit and receive data.
Normal work status: when you input High level at NO. 5 pin, HXJZ-873 turn into Normal work status,
10ms later, HXJZ-873 can transmit and receive data.
Remarks: if you keep the NO. 5 pin untouched, then HXJZ-873 in Normal work status.
2) Awaken from COM Port:
When HXJZ-873 sleeping in this saving power model, the current is under 11mA. When
you input data to
HXJZ-873 with COM port, HXJZ-873 turn into Normal work status after 10mS and can transmit the data. When
HXJZ-873
did not receive data in COM port in the period of 20 seconds, HXJZ-873 will turn into sleep status.
3) Awaken from Air:
When HXJZ-873 sleeping in this saving power model, the current is under 20mA. When HXJZ-873 in
this saving power status, HXJZ-873 works intermittently. When HXJZ-873 received awaken data from air,
HXJZ-873 will turn into normal work status after 10ms, it can receive data normally. When HXJZ-873 did
