I have been using WK-M and Naza for years but I have not used other acessories from DJI.
Recently I decided to have a go and I'm trying to decide what to buy.

But I'm not sure about what suits me better, if only BT module or 2.4GHz BT Datalink.

What are the specific diferences between them?

Do they also work with DJI A2 FC?
