If your firmware version is NUM_VERSION_A and then you will download version_a+.bin as your new firmware. If your firmware version can't be found through JSON file, and your firmware version is older than NUM_VERSION_B, then you will download "master" url specified version_b.bin as your new firmware. Sample Content of SB30.json { "master":{ "version":"NUM_VERSION_B", "url":"https://www.custurl.com/download/version_b.bin", ... }, "NUM_VERSION_A":{ "version":"NUM_VERSION_A+", "url":"https://www.custurl.com/download/version_a+.bin", ... } }
