No more laptops in the field!

This app is great. I love being able to change vtx channel too. My only comment would be to add the Led strip tab so we can change led color for racing. Then it will be complete!! Thank you!

A useful app, except for the CLI

I'm using the Speedybee app on a 2017 iPad Pro, with the Speedybee Bluetooth adapter and a BrainFPV RADIX FC. When I go to the CLI and issue any command which yields a lot of text output (DIFF ALL, DUMP, etc), the app drops characters...a LOT of characters. If you ever wanted to paste the output back into the FC, it would fall due to incorrect syntax and bad values for the command arguments. There seems to be no error checking or flow control. Data comes from the FC too quickly for the adapter and/or the app to process. I reached out to Speedybee, who replied saying "We tested it, it works." - totally ignoring the screen shots of it clearly not working! There has been no other communication from their support personnel.

I use my computer WAY less now since I can do almost everything in Betaflight using this app, thanks speedybee!

If I could update flight controller firmware with this I’d be 100% computer free:)
