3.5. Returned Data from Module

3.5.1 Returned data after the module is powered on

1). After the module is powered on, normally it needs about no more than 500ms to 1500ms(depending on the

actual track quantities in the storage device) initialization time. Once the initialization is done, the module returns a

data to MCU. If it does not return a data after more than the initialization time, it means there is an error for

initialization, and please check the hardware connections.

2). The returned data from module after initialization means the current effective storage device/online equipment.

For example, the module returns 7E FF 06 3F 00 00 03 xx xx EF. 0x3F is the returned command by module, and

0x03 represents USB flash and SD card are effective/online at the same time. See the details as below.

Online Equipment

Returned Data

USB flash online

7E FF 06 3F 00 00 01 xx xx EF

SD card online

7E FF 06 3F 00 00 02 xx xx EF

PC online

7E FF 06 3F 00 00 04 xx xx EF

USB flash and SD card online

7E FF 06 3F 00 00 03 xx xx EF

3). MCU can not send commands to control the module until the initialization of the module is done and a data is

returned, otherwise the commands sent by MCU will be ignored and also this will effect initializing of the module.
