Read RFID card number protocol

Data type: 0x00

Data segment format when receiving commands:

Data length is 0

Data segment format when responding to commands:

Obtained card number

Example: Card number: 08 FA AF F2 50 01 04 E0

Sent: 7E 00 00 00 7E

Received: 7E 00 00 08 FA AF F2 50 01 04 E0 5E

Read RFID card data protocol

Data type: 0x01

Data segment format when receiving commands:

Byte0: Start block number

Byte1: Number of consecutive read blocks

Data segment format when responding to commands:

Obtained block data

Example: Read the 00th block, continuously read 8 blocks of data;

Sent: 7E 01 00 02 00 08 89

       Received: 7E 01 00 20 31 32 33 34 35 36 37 38 39 30 30 32 00 00 9F 4E 67 75 79 65 6E 20 56 61 6E 20 42 00 00 00 00 FA

Write Card Data Protocol

Data segment format when receiving commands:

Byte0: Start block number

Byte1~ByteN: Continuously written data

Data segment format when responding to commands:

Byte0: 0 write card successful; 1. Card write failure

Example: Write the 00th block, continuously writing 16 bytes of data;

Sent: 7E 02 00 11 00 39 38 37 36 35 34 33 32 31 30 32 34 30 07 9F

       Received: 7E 02 00 01 00 81

LED light and buzzer control protocol

       Data type: 0x03

       Data segment format:

Byte0：buzzer

Byte1：led_pwr

Byte2：led_net

Byte3：led_gps

Byte4：led_login

Byte5：led_rec

Byte6：led_alram

Byte7：led_cam0

Byte8：led_cam1

Byte9：led_cam2

Byte10：led_cam3

Byte_Value: The low 4 digit value (0: constant off, 1: constant on, 2: single flashing, 3: continuous flashing), when flashing, the high 4 digits         indicate the flashing frequency, flashing several times in 1 second, and the maximum should not exceed 5

Example: Net continuously flashing fast, GPS continuously flashing slowly, login always on, rec always on, cam1-4 always on
