android BLE simple app

I need an android app that can communicate with the bluetooth BLE blood pressure machine. Here are the details of communications (no UI no login,nothing fancy just basic app that communicate as per follows) Setup/Connection ============================= BLE UUID: receive：Service UUID for：0xFFF0， Characteristic UUID for：0xFFF1 send：Service UUID for：0xFFF0， Characteristic UUID for：0xFFF2 【 receive：Service UUID for：0000fff0-0000-1000-8000-00805f9b34fb， Characteristic UUID for：0000fff1-0000-1000-8000-00805f9b34fb； send：Service UUID for：0000fff0-0000-1000-8000-00805f9b34fb， Characteristic UUID for：0000fff2-0000-1000-8000-00805f9b34fb。 】 Command for communication ===================================== When the bluetooth of the mobile phone and the sphygmomanometer are connected successfully, the mobile phone sends[0xFD,0xFD,0xFA,0x05,0X0D, 0x0A] Report that the sphygmomanometer is successfully connected and can be measured. Meanwhile, the sphygmomanometer replied: [0xFD,0xFD,0x06, 0x0D, 0x0A],And start measuring. Pressure signals will be sent during the measurement of blood pressure:[0xFD,0xFD,0xFB,PressureH, PressureL,0X0D, 0x0A] After the measurement is completed, the sphygmomanometer send the following test results: [0xFD,0xFD,0xFC, SYS,DIA,PUL, 0X0D, 0x0A] ; The test results
