3.1.2. Operating Procedure
1. Install a USB-UART driver. You can download it from the following address:
http://www.ftdichip.com/Drivers/VCP.htm .
2. Insert a Micro USIM card into J303, and choose an appropriate USIM card according to different
hardware versions of the BC95-GR module.
3. Connect a rod antenna with the SMA connector on J304 (RF antenna connector).
4.
Switch J302 (UART Switch) to “MAIN UART TO USB” state.
5. Connect J301 to a PC via a Micro USB cable. When BC95-GR-TE-B is connected to the computer,
UART information is shown on the
“Device Manager” of the PC. “USB Serial Port (COM154)”
(corresponding to “USB Serial Converter A”) is connected to the main UART of BC95-GR and can be
used for AT command communication and data transmission. “USB Serial Port (COM156)”
(corresponding to “USB Serial Converter C”) is connected to the debug UART of BC95-GR and can
be used for debugging, debug log output and firmware upgrade. For details of port configuration, see
document [1]
