R4 firmware update with the cloud is in my experience completely hopeless. Load the IDE and connect the R4 directly to a COM Port and the upgrade firmware. This works if the PC does not already have to many devices using the USB. I think its about time OTA firmware upgrades just became and option when you OTA a script to the device. Cloud also seems very poor at telling you when there is new firmware available, and the devices page currently only ever shows the firmware that was loaded on that device when you connected it. This spoils a great product, I've wasted so much time hoping each cloud update would improve this deployment. I have a special PC with almost nothing else on for direct COM port firmware updates and when OTA scripts wont deploy. Use the IDE. Pretty poor if you've deployed your hardware to the field but it seems to be the only reliable way. Come on guys this is important!
