Operation Procedures Illustration

This chapter introduces how to use LTE OPEN EVB for testing and evaluation of Quectel LTE-QuecOpen
and Wi-Fi modules.

5.1. Power on Modules

5.1.1. Power on LTE-QuecOpen Modules

1. Connect the TE-A of respective modules to the EVB via connectors J0101 and J0102.
2. Insert a (U)SIM card into the U(SIM) card connector J0901 on EVB, and connect the antennas to the
TE-A.
3. Connect the EVB to a 5V power adapter, or connect the EVB to PC via USB to RS-232 converter
cable.
4. Switch S0301 (POWER) to ON state, then D0310 (VBAT ON/OFF indicator) will light up. Press the
S0403 (PWRKEY) for at least 100ms, then the module will be powered on and D0311 (power
ON/OFF status indicator) will light up.

5.1.2. Power on Wi-Fi Modules

Wi-Fi function is only supported on Quectel EC2x/AG35-QuecOpen module. BG96-QuecOpen does not
support the function.
1. Make sure EC2x/AG35-QuecOpen module is powered on if there is a need to test the Wi-Fi function
of them.
2. Connect the TE-A of Wi-Fi modules to the EVB via connectors J1001 and J1002, and then connect
the Wi-Fi antenna to the TE-A.
3. Connect the TE-A to PC via an Ethernet cable.
4. Send AT+QWIFI=1 command to EC2x/AG35-QuecOpen module to enable power supply for Wi-Fi
modules. For more details, please refer to document [2], [3] and [4]. Before sending the command,
please make sure the EVB has been connected to PC via USB to RS-232 converter cable.
