Getting XBEE S2C End Device Address through USART by PIC MCU

Hello,
Recently, I started using XBEE S2C modules in my project. I would like to get XBEE Device Address by sending commands to the XBEE module through USART. But, the XBEE Device doesn’t return any information. I used the API1 mode to connect with XBEE module. The Baud Rate is 9600 bps. The commands I use to get XBEE Device Address are described as below.

const uint8_t XBEE_ADDRESS_MAC_UPPER_4BYTE [] = {0x7E, 0x00, 0x04, 0x08, 0x52, 0x53, 0x48, 0x0A};
const uint8_t XBEE_ADDRESS_MAC_LOWER_4BYTE [] = {0x7E, 0x00, 0x04, 0x08, 0x52, 0x53, 0x4C, 0x06};

Could you please tell me how to do it correctly ?

Thanks.
