Description
The HC-05 Bluetooth Serial Port Profile (SPP) module is a classic wireless workhorse for embedded systems, built around a CSR core chipset. It facilitates transparent serial communication over Bluetooth, effectively replacing a physical UART cable with a reliable wireless link. Its dual master/slave capability allows it to initiate connections to other Bluetooth devices or accept incoming pairings, making it suitable for creating bidirectional data links between microcontrollers, PCs, and smartphones.
Engineered for stability, the module operates on the universal 2.4GHz frequency with Gaussian Frequency Shift Keying (GFSK) modulation. It features a configurable command mode accessible via AT commands for setting parameters like device name, PIN, and role. The integrated button simplifies the switching between data and command modes for on-the-fly configuration. With an operating temperature range of -20°C to +75°C, it is robust enough for indoor industrial telemetry, DIY automation, and portable data logging applications.
