From Spektrum:
In this video Tom explains to our fellow RC enthusiasts how, with the latest transmitter update (V1.09 or higher) and ESC updates (see update link below for log and version), you can adjust Firma Smart ESC settings right from your telemetry capable Spektrum surface transmitters! This currently is supported on the DX5C, DX5R, DX5 Pro, and DX5 Rugged models. DX6R update is coming soon to include this feature.
If you have or are looking into the Spektrum Firma Smart Sensored ESC for Crawlers, this is a MUST HAVE!
Please note this will not work on older transmitters, such as the DX4R AND it does not work with the DX3 or DX2e Active with the Dashboard app.
