It works! Use 115200 baud.

Works well with Arduino and BlueDisplay Android app, set baud rate to 115200, connect rx, tx, 5v, Gnd and reset. Module Rx goes to Tx Arduino and Tx of the module goes to Rx Arduino for those new to this type of communication.1. Connect the module as above.2. Install bluedisplay in the arduino.3 library. Select the flickering sketch from the bluedisplay.4 samples. Set the speed to 115200, comment out 9600.5. Upload to arduino.6. With the BLE module enabled, install the Bluedisplay app and then pair according to your phone/device's Bluetooth settings.7. Open the app on the device and select ET11.8. It should be possible to control the built-in Arduino LED through the application on the phone.9. Enjoy!
