Authentic product, 7-day warranty on manufacturing defects, fast delivery across India.\"\u003e\n\n\u003ch1\u003eBeacon Module BLE 4.0 nRF51822\u003c\/h1\u003e\n\n\u003cp\u003eThe Beacon Module BLE 4.0 nRF51822 is a compact Bluetooth Low Energy broadcasting module based on Nordic Semiconductor's nRF51822 chipset, designed for proximity-based location services and IoT applications. Professional developers, IoT engineers, and embedded systems specialists use this module to build beacon networks for indoor positioning, asset tracking, and proximity marketing solutions. This module solves the critical challenge of creating power-efficient, long-range wireless communication in battery-powered devices by leveraging BLE 4.0 protocol with ultra-low power consumption.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eThe Beacon Module BLE 4.0 nRF51822 operates on the 2.4 GHz ISM band using the Bluetooth Low Energy protocol, which consumes significantly less power than classic Bluetooth while maintaining reliable communication over distances up to 100 meters in open space. The nRF51822 chipset integrates a 32-bit ARM Cortex-M0 processor running at 16 MHz with 256 KB flash memory and 32 KB RAM, providing sufficient processing capability for beacon firmware, sensor integration, and real-time data processing. The module broadcasts iBeacon-compatible packets that can be detected by any BLE-enabled smartphone or tablet, making it ideal for retail analytics, museum navigation, and proximity-triggered notifications without requiring paired connections.\u003c\/p\u003e\n\n\u003cp\u003eWhat distinguishes this module is its exceptional power efficiency, consuming only 15-20 mA during transmission and less than 1 microamp in sleep mode, enabling battery operation for months or years depending on broadcast interval and battery capacity. The module features a built-in antenna with approximately 0 dBm transmit power, adjustable advertising intervals from 100 ms to 10 seconds, and support for multiple simultaneous beacon profiles. Its compact form factor, typically measuring 15x15x5 mm, makes it suitable for embedding in wearables, access cards, product tags, and IoT sensors while maintaining industrial-grade reliability and temperature stability from -20 to 60 degrees Celsius.\u003c\/p\u003e\n\n\u003ch2\u003eKey

the Beacon Module BLE 4.0 nRF51822, begin by selecting an appropriate power supply, typically a 3V coin-cell battery (CR2032) or regulated 3.3V source for continuous operation. Connect the module to your development environment using a UART interface or SWD debugging port, then flash the beacon firmware using Nordic's nRF51 SDK or pre-compiled iBeacon firmware. Configure the module parameters including UUID, major and minor values, transmit power, and advertising interval through serial commands or the nRF Connect mobile application, which provides real-time signal strength and packet reception monitoring.\u003c\/p\u003e\n\n\u003cp\u003eFor production deployment, mount the module in your target enclosure ensuring adequate clearance around the antenna for optimal radiation pattern, then program the desired beacon identity and settings. Verify beacon transmission using any BLE scanner application on iOS or Android devices to confirm proper packet broadcasting and signal strength at expected distances. For applications requiring firmware customization or sensor integration, leverage the ARM Cortex-M0 processor by developing custom applications in C using the nRF51 SDK, enabling advanced features like sensor fusion, local data processing, or conditional broadcasting logic based on environmental inputs.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the difference between iBeacon, Eddystone, and AltBeacon formats?\u003c\/summary\u003e\n\u003cp\u003eiBeacon is Apple's proprietary format using UUID, major, and minor values for device identification, widely supported on iOS and Android. Eddystone is Google's open-source format supporting multiple frame types including URL, UID, and telemetry data, offering greater flexibility for diverse applications. AltBeacon is an open standard providing vendor-neutral beacon identification. The nRF51822 module supports all three formats through firmware configuration, with iBeacon being the most universally compatible for consumer applications and Eddystone preferred for advanced IoT deployments requiring sensor data broadcasting.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow long will a CR2032 battery power this beacon module?\u003c\/summary\u003e\n\u003cp\u003eA standard CR2032 coin-cell battery (220 mAh capacity) can power the beacon module for approximately 6-12 months depending on advertising interval and transmit power settings. At a 1-second advertising interval with 0 dBm transmit power, expect roughly 6-8 months of continuous operation. Reducing the advertising interval to 2-3 seconds or lowering transmit power to -10 dBm can extend battery life to 12-18 months. For applications requiring multi-year operation, consider using higher-capacity batteries like AA or AAA cells, or implementing motion-triggered advertising that activates the beacon only when movement is detected.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I reprogram the nRF51822 module with custom firmware?\u003c\/summary\u003e\n\u003cp\u003eYes, the nRF51822 supports complete firmware reprogramming through the SWD (Serial Wire Debug) interface using Nordic's nRF51 SDK and development tools like Keil uVision or GCC toolchain. You can develop custom applications in C to implement advanced features including sensor integration, conditional broadcasting, local data processing, or two-way communication protocols. The module includes 256 KB flash memory for firmware storage, sufficient for sophisticated beacon applications with multiple profiles and sensor support. Programming requires an SWD programmer interface and familiarity with embedded systems development, though pre-compiled beacon firmware is available for straightforward iBeacon deployment without custom development.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the actual range of the beacon module in different environments?\u003c\/summary\u003e\n\u003cp\u003eThe theoretical range of 100 meters applies to open-air line-of-sight conditions with optimal antenna orientation. In practical indoor environments with walls, furniture, and interference, expect effective range of 20-50 meters depending on construction materials and radio frequency congestion. Concrete and metal structures significantly reduce range, while drywall and open spaces maintain better propagation. Transmit power adjustment from 0 dBm to -20 dBm provides range tuning capability, with -20 dBm reducing range to approximately 5-10 meters. For critical applications, conduct site surveys using the nRF Connect application to measure actual signal strength and range in your specific deployment environment.\u003c\/p\u003e\n\u003c\/details\u003e\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.
