[QUOTE="WingmanGoose, post: 102811, member: 18869"] Keep in mind that strong radio signals can interfere with electronics. WiFi and Bluetooth are not magical beams. It’s just frequencies of radio waves. Electronics have RFI shielding, but it’s not equal quality of shielding between makes and models. Likewise, varying devices have varying degrees of signal processing abilities. A cheaper device may not be able to shield and decipher multiple signals like higher quality devices. It’s even possible a premium device was built with sub-quality internal components. When using WiFi (without OTG), the phone is sending WiFi signals, the remote is sending WiFi signals to the phone and strong WiFi to the drone, the drone is emitting strong WiFi, and there’s the ever present background radio waves. That’s a lot of RFI when the remote and phone are right next to each other. I suspect the reason everyone gets such varying amounts of success (or failure) with using the Spark without an OTG is the RFI, and the quality (or lack of) RFI shielding in combination of the quality of the device guts.
