Castle Link for Android
 

Many Android devices can be a USB host. This means that you can connect Castle Link programming device directly to you Android. You just need an Android OTG cable like shown in this video

+ YouTube Video

.

So, I'm developing an Android application to program Castle ESCs from Android. Its alpha version available now for download. It currently supports 90% of desktop's Castle Link functionality. You can try it out by following the link: play.google.com/apps/testing/synergy.android.esclink

P.S. I'm a hobby enthuseast and I'm a professional programmer. However I'm not related to Castle Creations yet, and doing development independently. If you are from Castle, please send me a PM :)

Sounds great! I will have to dig out my old Castle Link to test this!

How about an IOS version ?

^^ Agreed.. I don't even like Android after getting accustomed to iOS. Haven't looked back.

The thing is iPhone doesn't have hardware nor software support for being USB host. As a big hardware manufacturer, Apple is not willing to use others hardware. Only hope is having Wifi/Bluetoth accessories from ESC vendors.
Gecky Android on the other hand is happy to accept all the stuff like USB sticks, keyboards, missile launchers... :)

You need to contact Castle Creations via RC-Monster. Here is the link. The owner wants to talk to you!!
