Description

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 less resource 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 to set Bluetooth connection interval and control different forwarding rates (dynamic power adjustment) and adjust Tx power, customize advertisement data, customize device identification, set data delay (user MCU serial port reception preparation time).
