1. If you choose auto-upgrade, please use the file MECHEN_M30.HEX

Please pay attention that there should be only one MECHEN_M30.HEX saved in the device, or the auto-upgrade cannot be realized.

For example, when you have both MECHEN_M30(1).HEX and MECHEN_M30.HEX saved in the device at the same time, the device is nable to execute the auto-upgrade.


2. If you choose to upgrade the firmware by using the upgrade tool, please select the file in .fw format.
