I used single bank example. When I made the zip for OTA, I specify the device type and device revision as the same as the bootloader codeen-USTelligent Community 13Mon, 11 Jan 2016 06:20:35 GMTRE: Modifying some info in Manifest.json file won't fail OTAhttps://devzone.nordicsemi.com/thread/41994?ContentTypeID=1Mon, 11 Jan 2016 06:20:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed4c98b1-6e34-4805-b28a-1d68f64aba80mc<p>Thank you Wojtek,</p> <p>This confirm my analysis that the json file is only used by Nordic phone app tool and was not in over the air.</p><div style="clear:both;"></div>RE: Modifying some info in Manifest.json file won't fail OTAhttps://devzone.nordicsemi.com/thread/41993?ContentTypeID=1Fri, 08 Jan 2016 10:38:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:23836768-cf20-4ea2-ac91-1628d22b9953Wojtek<p>When you create zip, it has .dat file next to json file. It contains almost the same data as json, but in binary. I think it is used in DFU OTA procedure, not json file directly.</p><div style="clear:both;"></div>
