I believe you can only pair the repeater to one device at a time. In order to pair to another device you have to reset the repeater. That will clear the settings.
Note that when you connect the WiFi signal to the drone, when you use the extender you are selecting the Tello PLUS via the extender. When you fly the drone without the extender you are just connecting to the Tello without the word "Plus" after it. You have have selected another name for the drone but you know what I mean. "Plus" means thru the extender.
I give up! I've watched the video above multiple times as well as numerous other videos on YouTube to try to get my tello and wifi extender setup. All the instructional videos stop just short of all details needed. Perhaps someone can answer a few questions here:
1. The light on the extender is solid blue. However, it still appears to be trying to add a device and keeps saying "bring the phone closer to device and retry". Which device is it referring to? The extender or the Tello? I've moved all 3 devices to right next to each other. They are literally on top of each other and I still get the same message with a solid blue light? Doesn't the solid blue light indicate that it is connected?
2. When I look for WiFi connections on the phone I now see my TelloDrone (the wife of the drone itself) and now also another wifi connection called TelloDron-plus. What is that? Is that the extender wifi?
3. As all of this is pretty much as clear as mud, how do I know that the extender, Tello and phone are all connected and in sync?
4. Is the phone supposed to connect to the extender wifi?
Where are step by step instructions on who to accomplish available?? This is maddening!
