My OTG procedure (DJI GO 4
4.2.12):
- Turn on Remote Control (RC). Wait for solid red.
- Plug in OTG cable in phone.
- Plug other end in RC.
- Choose DJI GO 4 app in popup window.
- Wait until GO 4 app is open and it says "RC Connected" in lower left corner.
- Power up your Spark. Try to place RC as close to Spark as possible. (DJI recommend 20 cm)
- Bonding between RC and Spark should take less than 30 sec.
- Hit GO FLY!
This is absolutely fail-safe method!
If for some reason you want to change channels, lower numbers is 2.4 GHz and higher numbers is 5.8 GHz.
In CE area 2.4 GHz channel is preferred.
To change between bands/channels:
- In Wifi section of settings, choose "Custom".
- Where it says Channel Index, tap one of the channels.
- Tap "Apply" at the bottom of the page.
- Power down your Spark (Air-craft)
- Power up your Spark again.
- Within 30 sec you will see new channel has been set.
This is also fail-safe method!
FLY SAFE!
