HM-BT4502 Bluetooth Low Energy (BLE) Pass-through Module
₹510.00
HM-BT4502 is a wireless data pass-through module based on CMT4502 Bluetooth Low Energy 5.0 chip. By connecting with MCU, it can quickly realize the connection and data communication between the module and Bluetooth devices such as smartphones and tablets. MCU takes up fewer resources and development is simple.
HM-BT4502 BLE can be set with AT commands. Basically, it can support AT commands for software reset and get MAC address. Moreover, the AT commands can also be used toset Bluetooth connection interval and controldifferent forwarding rates (dynamic power adjustment) andadjust Tx power, customize advertisement data, customize device identification, set data delay (user MCU serial port reception preparation time).
Â
Features:
- Universal serial port design, full-duplex two-waycommunication, minimum baud rate support 9600 bps
- Default connection interval is 30 millisecond, fast connection
- Support 2M symbol transmission and244 bytes packet transmission
- Support AT commands for basic settings
