Data Time Intervals
For example Test time data every 10 minutes, when a change of state is detected the data
will be upload, the state remains unchanged in next intervals, and no data will be uploaded.
The data will be uploaded periodically like as heartbeat the data interval default 4 hours can
be modified, specific reference to the agreement.
State change means:

Make sure the position of the jumper cap is switched to the hollow position. If it is
placed at solid position module configuration cannot be completed.
Check if TTL and device RX, TX connection is correct, if the connection is wrong,
there will be no reply sending instructions.
Confirm the baud rate is the correct choice of baud rate, the correct should be
115200.

corresponding equipment.
Notes:
1. When the device is at Sleep mode sending instructions will be invalid.
2. Before sending instructions please click enter, and then send.
3. The command is sent in hexadecimal format except for configuring APN for details refer
to the protocol.
4. Check whether the RX and TX of the TTL and the device are correctly connected. If the
connection is reversed no output is displayed on the serial port after the device is powered
on, and the device cannot be configured.
