Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003eSIM808 Bluetooth Compatible GSM\/GPRS\/GPS Module\u003c\/h1\u003e\n\n\u003cp\u003eThe SIM808 is a compact quad-band GSM\/GPRS\/GPS module with integrated Bluetooth connectivity, designed for IoT applications requiring simultaneous voice, data, and location tracking capabilities. Professional engineers and IoT developers use this module to build GPS tracking systems, fleet management solutions, emergency alert systems, and remote monitoring devices that require cellular connectivity and real-time positioning. This module solves the critical problem of integrating multiple communication protocols into a single compact form factor, eliminating the need for separate GPS, GSM, and Bluetooth modules in space-constrained applications.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\n\u003cp\u003eThe SIM808 module operates on quad-band GSM frequencies (850\/900\/1800\/1900 MHz) with integrated GPRS Class 12 data connectivity, enabling reliable cellular communication across global networks. The embedded GPS receiver provides high-sensitivity positioning with TTFF (Time To First Fix) of approximately 35 seconds in open sky conditions, while the Bluetooth 2.1 interface allows wireless pairing with mobile devices and peripherals. The module communicates via standard AT commands through a UART interface, making it compatible with microcontrollers like Arduino, STM32, and Raspberry Pi without requiring complex driver installations.\u003c\/p\u003e\n\n\u003cp\u003eWhat distinguishes the SIM808 is its integrated power management system with built-in charging circuit for Li-ion batteries, eliminating the need for external power conditioning circuitry. The module features a ceramic antenna for GPS reception and an external GSM antenna connector, providing flexibility in antenna placement for optimal signal strength. Operating at 3.3V to 4.2V, the SIM808 draws approximately 100mA during GSM transmission and 80mA during GPS operation, making it suitable for battery-powered applications with proper power management design.\u003c\/p\u003e\n\n\u003ch2\u003eKey

with your microcontroller via UART pins (RX\/TX) at 115200 baud rate. Insert a standard 2G GSM SIM card into the module's SIM slot, ensuring the card is activated with an active data plan for GPRS functionality. Power the module through the dedicated power pins with a stable 3.3V to 4.2V supply, preferably using a regulated power supply or battery with capacitive filtering to handle current transients during GSM transmission. Initialize the module by sending the AT command \"AT\" to verify communication, then configure network settings using \"AT+CPIN?\" to check SIM status and \"AT+CREG?\" to verify network registration.\u003c\/p\u003e\n\n\u003cp\u003eFor GPS positioning, enable the GPS engine using \"AT+CGNSPWR=1\" and allow 35-45 seconds for the first fix acquisition. Retrieve coordinates using \"AT+CGNSINF\" which returns latitude, longitude, altitude, speed, and course data in standard NMEA format. For GPRS data transmission, establish a TCP\/IP connection using \"AT+SAPBR\" commands to set the bearer profile, then use \"AT+HTTPINIT\" for HTTP operations or \"AT+CIPSTART\" for socket connections. Configure Bluetooth pairing mode with \"AT+BTPOWER=1\" and \"AT+BTVIS=1\" to enable device discovery, then pair with your smartphone using standard Bluetooth pairing procedures. Always implement proper error handling for AT command responses, as network conditions and GPS signal strength directly affect module behavior and response times.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between SIM808 and SIM900 modules?\u003c\/summary\u003e\n\u003cp\u003eThe SIM808 integrates GPS and Bluetooth capabilities that are not present in the SIM900, which is a GSM\/GPRS-only module. The SIM808 is ideal for applications requiring location tracking and wireless peripheral connectivity, while SIM900 is suitable for basic cellular communication. SIM808 also includes a built-in battery charging circuit, whereas SIM900 requires external charging management.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow accurate is the GPS positioning on the SIM808?\u003c\/summary\u003e\n\u003cp\u003eThe SIM808 GPS receiver provides horizontal accuracy of approximately 10 meters under open sky conditions with clear satellite visibility. Accuracy degrades in urban canyons or indoor environments due to signal obstruction. The module supports DGPS (Differential GPS) for enhanced accuracy if your application requires sub-10-meter precision. Cold start acquisition takes 35-45 seconds, while warm start (with recent ephemeris data) takes 5-10 seconds.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eCan I use the SIM808 for voice calls in addition to data and GPS?\u003c\/summary\u003e\n\u003cp\u003eYes, the SIM808 supports voice calls through its GSM interface. You can make and receive calls using AT+D command for dialing and AT+A for answering. However, voice and data cannot operate simultaneously on 2G GSM networks. The module will disconnect GPRS when handling voice calls and automatically reconnect afterward, making it suitable for applications requiring both voice alerts and data transmission.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat power supply specifications should I follow for reliable operation?\u003c\/summary\u003e\n\u003cp\u003eUse a regulated 3.3V to 4.2V power supply with minimum 2A capacity to handle GSM transmission current spikes reaching 1.5A. Include a 100µF electrolytic capacitor and 100nF ceramic capacitor close to the module's power pins to stabilize voltage during transients. If using a battery, ensure it can deliver 1.5A peak current without voltage sag below 3.3V. Improper power supply design is the most common cause of module reset and communication failures.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eHow do I enable and use Bluetooth connectivity on the SIM808?\u003c\/summary\u003e\n\u003cp\u003eEnable Bluetooth using AT+BTPOWER=1 command, then set visibility mode with AT+BTVIS=1 to allow device discovery. The module will appear as \"SIM808-BT\" in your smartphone's Bluetooth device list. Pair using the default PIN (typically 0000 or 1234), then establish serial port profile connection. Once paired, you can send AT commands through Bluetooth serial connection for remote configuration and data retrieval without cellular connectivity.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eOrders are dispatched within 1-5 business days from our Bengaluru warehouse.
