How to Use:

1. Insert SIM Card:
   • Insert a Micro SIM card into the slot on the module. Ensure the card is active and has sufficient credit/data plan.
2. Connect Antenna:
   • Attach the external antenna to the module for stable GSM/GPRS reception.
3. Connect to Computer:
   • Plug the module into a computer’s USB port using a USB cable. The module will be powered through USB, and a virtual COM port will be created for communication.
4. Install Drivers (if necessary):
   • If the module is not automatically recognized, install the necessary USB drivers provided by the manufacturer.
5. Communication Setup:
   • Open a serial terminal on the computer (such as PuTTY or Arduino IDE Serial Monitor).
   • Set the baud rate to match the module’s default (usually 9600 or 115200).
6. Send AT Commands:
   • Begin sending AT commands to configure the module. For example, “AT” checks for module readiness, and “AT+CSQ” checks signal quality.
   • Use “AT+CMGF=1” to set SMS to text mode, and “ATD<number>;” to make a call.
7. Bluetooth Configuration:
   • Use AT commands to enable and configure Bluetooth. For example, “AT+BTPOWER=1” turns on Bluetooth.
8. GPRS Data Connection:
   • To connect to the internet, use “AT+CSTT” to set the APN, “AT+CIICR” to bring up the wireless connection, and “AT+CIFSR” to get the IP address.
9. Monitor and Control:
   • Monitor the status of your device and control it via USB or UART, depending on your application needs.

This module is ideal for projects requiring reliable GSM/GPRS connectivity along with Bluetooth capabilities, such as remote monitoring, wireless data transmission, and IoT applications.
