[Tharak]

Hi Mate,

I need to upgrade image through ota but how is i dont know now am trying using nrfconnect mobile apk but i dont have prior knowledge is there way to upgrade mcu bootloader please help me and if possible please provide tutorial also

Is this the MCU bootloader on the BL653 DVK board or an MCU bootloader on the onboard nRF52833? If it's something specific to the BL653 DVK I think you need to ask Laird about that.

As to how to create a botoloader package using nrfutil that is explained by my colleague Terje in this ticket. Then you need to move the bootloader file over to your Android device and connect to the device you want to do a DFU on.

Best regards,

Simon
