I have the iPad linked as the master and it works fine but cannot link the S5 as the slave. I set it as a slave and get a constant purple light but it states it is not connected to the camera and there is no video or gimbal control When i seek permission for the gimbal control it states the controller has it. I have the latest app on the S5 and have tried the red button on the inspire. Could it be that you cannot have an iOS device as a master and an android device as the salve? Any help appreciated.
