DJI MSDK version: 4.16.4

Hi, 

I'm facing a issue that onComponentChange() does not return remote controller key for M210 when I switching connection between M210 and M300.

I connect the remote controller with my tablet.

And if I only connect with one drone's remote controller (M210 or M300), and I can connect and disconnect with the drone over and over again, the onComponentChange() will return remote controller key for both drones.

The issue only happen when I start switching drones between M210 and M300, the onComponentChange() does not return remote controller key for M210, for example:

1. M210 -> M300 -> M210: first connect to M210, onComponentChange() does return remote controller key, but once I disconnect M210 and reconnect to M300 (return remote controller key), and connect to M210 again, onComponentChange() is not return remote controller key for M210

 

2. M300 -> M210 -> M300: first connect to M300, onComponentChange() return remote controller key, and reconnect to M210, there is no remote controller key coming in, and connect to M300 again, the remote controller key is return.

 

So just wondering if there any way that I can solve this issue? 

 

Thank you

  Seems like a bug comes from when chaning from M300 RC to M210 RC. But this is a very minor issue, by re-starting the app it should work. We will have a look but it is a very low priority issue. Can your provide me the model name of your M210 RC?

  It is working fine on my side. By the way, when you plug-in the cable, a window will pop up and ask you which app you want to connect with. After choosing the MSDK app, the MSDK app will restart and the onComponentChange is called.

  yeah, I did choose the MSDK app every time I connect to a drone, but onComponentChange only update when I not switching drones. 

  The issue is onComponentChange not updating M210 remote controller key when I connect to M300 first and reconnect to M210. And M210 onComponentChange updating remote controller key if I restart the app.

  So just wondering if there any way that I don't have to restart the app and getting M210 remote controller key? 

  Thank you!
