Tool Connection

3.1. Connection Configuration

Connect the module to the PC through the Micro USB port on the TE-B. After the connection completes,
the PC will automatically install the USB-UART driver. After the driver is installed, the following 4 ports will
appear on the PC:
Generally, the first port, "USB Serial Port (COM36)", is used for AT communication, and the third port,
"USB Serial Port (COM38)", is used for log capture. Yet the port display order may vary with different PCs.
⚫
NOTE
The actual port names may be different from these shown in the figure above due to different drivers
installed.
