EHMB06 is a dualmode audio and data transmission module supporting Bluetooth 5.1, it is based on Qualcomm QCC3021 chip with built-in 32M flash, supports 120MIPS Kalimba DSP, supports enhanced audio and DSP applications (AAC, SBC codec, 1-mic CVC). Supports GATT, A2DP, AVRCP, HSP, HFP, SPP and PBAP features for connecting with smart devices.

The module's BLE and smartphone connection must use APP, Ehong can provide APP interface technical support, or you can directly download Ehong demo APP for testing.

Ehlink@ AT command set Through the UART interface communication, designers can easily design different Bluetooth products according to their requirements, such as: HS/HF, A2DP, AVRCP, SPP, HID, GATT, etc. In addition, the module's software supports TWS protocol, users can easily achieve two Bluetooth speakers synchronized music playbackfunction, bringing you unparalleled music enjoyment!
