DFU Bootloader version:

• SDK version: 29
• Bonding used: yes
• Library version:1.11.0

Device information:

• Device: Samsung s10
• OS: Android 10

Your question: When upgrading the device, an exception occurred.The location of the exception at SecureDfuImpl.class@onCharacteristicChanged characteristic.mValue ： [96,3,3] I can be sure that the installation package is fine and all other devices can be upgraded normally.What to do about it?

thanks.
