Do you experience any of these symptoms when using Litchi:
If you are experiencing any of these issues then it might be your mobile device.
The reason for this is most likely the DJI SDK (software development kit) which 3rd party app providers use to develop their app for DJI drones.
In July 2017 DJI released SDK 4.0. This latest SDK is the most demanding one yet. For example the Nexus 7 worked without issues on the previous SDK, but on SDK 4.0 the Nexus 7 struggles.
According to Litchi they tested the following devices, using a Mavic Pro with the latest DJI firmware (results may vary with other drone models):
- Nvidia Shield Android 7: OK
- Galaxy S8+ Android 7: OK
- Galaxy S6 Edge Android 7: OK
- Galaxy Note 5 Android 7: OK
- Galaxy Tab S2 Android 7: OK (can have some connection issues depending on model)
- Galaxy Note 4 Android 4.4: Not OK (a lot of lag)
- Nexus 9 Android 7: Not OK (way too much lag)
In the above list the 2 slowest devices (note 4 and nexus 9) used to be OK before SDK 4.0.
It seems that the SDK is more demanding on Android then iOS.
Litchi have not published a detailed list but the above Android examples are an idea of what will work.
iOS devices they recommend are: iPad mini 4, iPad 2017, iPad Air 2, iPad Pro, iPhone 6s or anything higher.
In general they recommend at least 2 Gigs of RAM. Also the software version makes a difference as the Note 4 above had issues but it ran on Android 4.4., but my Note 4 on Android 6 runs fine.
