Communication via Micro-USB Interface Step 1: Connect the EVB and the PC with a Micro-USB cable through Micro-USB interface, and then switch POWER to ON state to power on the EVB. Step 2: Run the USB flash drive on PC to install the USB driver. The USB port numbers can be viewed in Device Manager of the PC after the USB driver is installed, as shown below. Figure 9: USB Ports Step 3: Install and then use the tool QCOM provided by Quectel to realize the communication between L26-T module and the PC. The following figure shows the COM Port Setting of QCOM: select the correct “COM Port” (USB Port shown in the above figure) and set the correct “Baudrate” (the default value: 9600bps). For more details about the usage of QCOM, please refer to document [4]. Figure 10: COM Port Setting of QCOM L26-T_EVB_User_Guide 14 / 22 GNSS Module Series L26-T EVB User Guide 4.2.
