ADIY HLK-B50 TTL Module

The ADIY HLK-B50 TTL MODULE is a high-performance, dual-mode Bluetooth (BLE 5.0 and Classic SPP) serial-port transparent-transmission module. It is built around a 32-bit ARM Cortex-M3 core running at up to 48 MHz and is designed to bridge a user’s serial device to a Bluetooth network with minimal firmware effort. The module supports simultaneous SPP and GATT transparent transmission, allowing embedded devices to exchange data wirelessly with high stability and throughput. Firmware version V1.17 (Build 26052010) adds enhanced AT-command compatibility. In addition to the native HLK-B50 command set, the module accepts many of the commonly used AT commands from the HC-05 and BT986 modules, which simplifies migration and improves software reuse for existing designs. While most frequently used commands are supported, full command compatibility is not guaranteed — always refer to the AT Command Reference (Section 8) for the authoritative list of supported commands.
