Hello I am new to this forum.
I bought a T2_L4A_8650C DAB radio module and now I am trying to use the UART interface.
My hardware setup is shown in the attached image: KeyStone8650C_TestPCB_Schematic_V2.pdf .
I connect to the UART port with 57600 baud, and now I expected to be able to send commands to the DAB.
As soon as I turn on the power, I receive the message "MPTEST" once every second from the DAB UART.
When I send a SYSTEMGetSysRdy command I expect to get a ACK or a NAK back.
No matter which command I send it keeps on sending "MPTEST"
Do anyone know what MPTEST means , and why the module keeps sending this message ?

Code:
serialPort.writeInt(0xFE); //startbyte
serialPort.writeInt(0x00); //command type
serialPort.writeInt(0x00); //commend id
serialPort.writeInt(0x01); // Serial number
serialPort.writeInt(0x00); //Dar length 2 bytes
serialPort.writeInt(0xFD); //end commandNo matter which command I send it keeps on sending "MPTEST"
