4.2. Important Note

The URC of +QIND: "FOTA","START" indicates the firmware upgrade process really starts. If the Ext.

MCU receives this URC after executing AT+QFOTADL command, please

do NOT power off the module

until the firmware is upgraded successfully and +QIND: "FOTA","END",0 is received. Then the module will

reboot and enter into normal mode automatically.

During upgrading process, if the Ext. MCU does not receive any URC in four minutes after the last URC is

returned, then the module can be rebooted.

Meanwhile, it is recommended to set a flag on Ext. MCU to mark the task of the firmware upgrading and

clean it after successful upgrading.
