The response value “0” means USB Disk start-up mode, and the value “1” means Modem start-up mode. If user wants to switch the mode from USB Disk start-up to Modem start-up, a special SCSI command whose code is 0xFF and length is 1, needs to send to the module. It can be sent by CreateFile and DeviceIoControl for windows OS.
Page 30 of 31 If user wants to switch the mode from Modem start-up to USB Disk start-up，the AT command AT+BOOTDEV=0 needs to send to the module. When the module is restart it will be changed to USB Disk start-up mode. In the Modem mode, the AT command AT+DEVCHG will change the device to be a USB Disk directly. In USB Disk mode, the USB Disk is a read-only device by default. If user wants to change the module to be read-write, it needs to switch to modem mode firstly, then use AT commands AT+FILEMODE=0 and AT+DEVCHG. The module will be read-only again after restart.
