Hi  every one,

   I compiled externalized ColorLight with JN-AN-1218. I want to change the version of Ota file and how to modify it.

Hi Daniel, I hope you're doing well!

 

Could you please take a look at this document here? Appendix B has some related information to the values related to OTA version.

 

The example provided in said document is for a null OTA file, but the concept applies to regular OTA files as well.

As you can see in the image below, the first two bytes correspond to Manufacturer code, then two bytes for image type, and one byte for version number, followed by 3 "zero" bytes.

You can also change the version number using JET, as explained in section 3.3 of the same document.

 

Please let me know if you need more information.

 

Best regards,

Sebastian
