FAQ Section
1. What is the fundamental difference in RF performance between the E104-BT14SP and E104-BT14SX?
The 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.
2. Does the E104-BT14S series support both Master and Slave Bluetooth roles?
Currently, 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.
3. How does the EWT104-BT14SP development board assist in the engineering phase?
The 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.
