I’ve checked about the DFOTA for BC660K in the pdf file located at the SDK: DFOTA Application Note.
It states that we must send the new firmware versions to Quectel, then the Delta is generated and sent it back.
But, checking at the forum here, other modules comes with the delta-gentools in the SDK.
I needed documents and tools regarding sdx Delta gentools v3.13 I have created all the files but unable to make script please provide me required tools and documents
