I have recently got a Breeze and due to warnings from this forum and other reviews have not upgraded to the latest firmware. However I am interested in using the controller that comes with the FPV kit. Already running the latest version of the iOS Breeze Cam app that has the FPV option, but is there a required firmware version needed to use the controller? Am a little hesitant about upgrading the firmware only to have wifi dropouts like others have complained about.
