Airdata provides an easy sync option ...

7/21/2017

If you fly a lot or run a drone business then you are going to want to get an account with Airdata.com.

Its free but you can get paid options too.

The beauty of this service is it automatically syncs all your flight data into the cloud and gives you actionable intelligence at your fingertips. No more pen and paper at the flying field and wasting precious time and energy doing log keeping. AirData will do it all for you.

In today's blog I discuss how Airdata provide an easy way to sync with the flights in the DJI Go app and this is especially useful for those with a Phantom 4 Pro + drone which could not use Airdata until now.

As always happy flying

Litchi handset issues

7/14/2017

Do you experience any of these symptoms when using Litchi:

lag or slow performance e.g. pressing a button on the app & it doesn't respond instantly
video freezes for a second or longer
erratic gimbal movements

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.

To improve the performance of your mobile device, please follow these guidelines:

make sure there are no apps running in the background before you start Litchi
enable “Hardware Decoding” in the general settings (iOS only)
make sure your mobile device is not in power saving mode (has various names on Android - called “Low Power Mode” on iOS)
set the “Preview quality” to 4Mbps in the general settings (for Lightbridge based drones only, not P3S/P34K/Mavic Pro)
Disable Internet (for example switch to airplane mode) to prevent the DJI development kit to continuously send analytics data while you fly
Make sure the Histogram is disabled (camera setting)
Do not use screen recording as that will increase the requirements a lot - make sure there are no interference where you fly
make sure “Full HD Stream” is disabled in the camera settings (for Mavic Pro/P4 Pro/Inspire 2)

As always happy flying
