Smart Wearable Devices and Health Monitors\u003c\/h3\u003e\n\u003cp\u003eDue to the ultra-compact form factor (10*10mm for the E104-BT14SX) and low-power BLE 5.4 protocol, these modules are highly suited for battery-powered wearable health devices. They operate primarily in slave mode, seamlessly transmitting physiological data via transparent UART transmission to mobile applications with minimal power consumption, significantly extending battery life.\u003c\/p\u003e\n\u003ch3\u003e2. Industrial Data Acquisition Systems\u003c\/h3\u003e\n\u003cp\u003eIn factory environments with high interference, the E104-BT14SX equipped with an external IPEX-3 antenna ensures robust RF performance and extends the communication range up to 320m. Engineers can integrate this module with existing Ebyte IoT sensors or PLCs to establish a reliable local wireless sensor network for real-time equipment status monitoring without extensive cabling.\u003c\/p\u003e\n\u003ch3\u003e3. Smart Home Automation Hubs\u003c\/h3\u003e\n\u003cp\u003eThe E104-BT14SP utilizing the built-in PCB antenna provides a cost-effective, space-saving solution for smart home appliances like lighting controllers or smart locks. The module supports low power broadcasting and OTA configuration, allowing home automation systems to efficiently discover nodes and push remote firmware updates smoothly without physical intervention.\u003c\/p\u003e\n\u003ch3\u003e4. Automotive On-Board Diagnostics (OBD)\u003c\/h3\u003e\n\u003cp\u003eFor fleet management and automotive telemetry, the module's standard UART interface facilitates easy integration with vehicle MCUs. It enables transparent data forwarding of vehicle diagnostics to a smartphone or a centralized dashboard via a stable BLE 5.4 connection, providing real-time analytics for maintenance engineers.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eFAQ Section\u003c\/h2\u003e\n\u003ch3\u003e1. What is the fundamental difference in RF performance between the E104-BT14SP and E104-BT14SX?\u003c\/h3\u003e\n\u003cp\u003eThe core difference lies in their antenna design and subsequent communication range. The E104-BT14SP utilizes a built-in PCB antenna optimized for compact environments, achieving a range of up to 200m. The E104-BT14SX features an IPEX-3 connector for external antennas, which extends the reliable transmission distance to 320m, making it ideal for deployments requiring deeper signal penetration.\u003c\/p\u003e\n\u003ch3\u003e2. Does the E104-BT14S series support both Master and Slave Bluetooth roles?\u003c\/h3\u003e\n\u003cp\u003eCurrently, the firmware for these modules is engineered specifically for the Slave role. This includes robust support for low power broadcasting, transparent UART data transmission, and over-the-air (OTA) configuration, which fulfills the primary requirements for end-node IoT devices communicating with central gateways or mobile platforms.\u003c\/p\u003e\n\u003ch3\u003e3. How does the EWT104-BT14SP development board assist in the engineering phase?\u003c\/h3\u003e\n\u003cp\u003eThe EWT104-BT14SP testing kit drastically reduces hardware prototyping time. By featuring a pre-soldered E104-BT14SP module on a 30*59.6mm breakout board with standard pin headers, developers can bypass custom PCB layout during initial evaluations. It allows immediate connection to a PC or MCU for UART communication testing and AT command configuration.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Ebyte Official Store - IoT Module Manufacturer","offers":[{"title":"E104-BT14SP","offer_id":48605671719117,"sku":"E104-BT14SP","price":0.95,"currency_code":"USD","in_stock":true},{"title":"E104-BT14SX","offer_id":48605671751885,"sku":"E104-BT14SX","price":0.95,"currency_code":"USD","in_stock":true},{"title":"E104-BT14SX+TX2400-FPC3-5015","offer_id":48605671784653,"sku":"E104-BT14SX+TX2400-FPC3-5015","price":1.35,"currency_code":"USD","in_stock":true},{"title":"EWT104-BT14SP+E15-USB-T3","offer_id":48605671817421,"sku":"EWT104-BT14SP+E15-USB-T3","price":6.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0615\/5911\/1885\/files\/3034a1133efe01daba919094b70c6310_b9af4fdb-01c5-4058-b7cb-3f7fbc837537.jpg?v=1784870223","url":"https:\/\/ebyteiot.com\/de\/products\/ebyte-e104-bt14s-series-ble-5-4-uart-module-pcb-ipex-ewt104-bt14sp-test-kit-ultra-low-power-iot","provider":"Ebyte Official Store - IoT Module Manufacturer","version":"1.0","type":"link"}
