Detail

EH-MB18 is a Bluetooth 3.0+4.0 dual-mode audio and data transmission module based on CSR8670 with built-in 16M flash, 80MIPS Kalimba DSP, enhanced audio and DSP applications (t Apt-X, AAC, Apt-XLL, SBC codec). Supports GATT, A2DP, AVRCP, HSP, HFP, SPP, iAP 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 UART interface communication, designers can easily design different Bluetooth products according to their requirements, such as HS/HF, A2DP, AVRCP, SPP, HID, GATT and so on. In addition, the module's software supports TWS protocol, users can easily achieve two Bluetooth speakers synchronized music playback function, bringing you unparalleled music enjoyment!
