Casting to my TV while camping Do I need a cable to be able to mirror a video from my phone without WiFi?
While using Bluetooth I only get sound no images….

That depends on what you are casting to.
Casting is only supported by a limited amount of apps on the iPhone as its a Google technology.
If you mean Airplay, then you may not need a cable if trying to Airplay to an Apple TV, but you also don't use bluetooth for this.
Bluetooth simply transmits audio. You cannot use Bluetooth to cast or Airplay.
