Operation Procedures Of Using Bc66-Te-B Alone; Operation Procedure With Multi Boards - Quectel BC66-TE-B User Manual

3.1.2. Operation Procedures of Using BC66-TE-B Alone

1. Install USB-UART driver which can be downloaded from the following link:
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.
2. Insert a Micro-SIM card into J303, and please note that a NB-IoT USIM card should be selected.
3. Connect the rod antenna with SMA connector on J304 (RF antenna connector).
Switch J302 (UART Switch) to "MAIN UART TO USB" state.
4.
5. Connect the J301 (USB power supply interface) with PC via Micro USB cable. After turning on
BC66-TE-B, UART port information will be shown on "Device Manager" of PC. Interface0 is the main
UART port and can be used for AT command communication, data transmission and firmware
upgrading. Interface1/2 are auxiliary UART and debug UART respectively, both of which can be
used to output log for firmware debugging. For details of UART configuration, please refer to
Quectel_BC66_Hardware_Design.
NOTE
In the procedure, S101 can be used to turn on BC66 module, S102 can be used to reset the module, and
S103 can be used to wake up the module from PSM.
