Hello.
I’m currently working on controlling 3 ANAFIs by one PC using Olympe.
There is a connection problem I can not solve.
The problem is sudden disconnection.
The disconnection occurs between Olympe-ANAFI not PC-ANAFI.
This problem has never been shown up with sole drone but shown up while controlling multiple ANAFIs.
I have no idea why the problem happens.
There are mainly 2 different types disconnection.
TYPE1 : Disconnection probably caused by other Wi-Fi devices
I use 2.4 GHz Wi-Fi band to control ANAFIs.
When a device exists that use Wi-Fi channel same(or close) as ANAFI, My ANAFIs disconnect easily.
I can’t get it that if Wi-Fi channel interference is main cause of this problem, disconnection may occur at the time of connection between My PC(Ubuntu) and ANAFIs.
But the disconnection always occurs after Olympe creates drone objects and successfully send command and receive data from ANAFIs.
TYPE2 : "Error cmd interface seems to be destroyed"
This type disconnection occurs at connection phase using Olympe.
When this type problem happens, the error output would never end until I force termination by Ctrl+C.

Are there any solution for this disconnection problem?
Have someone ever achieved multiple ANAFIs control without any error?
Thanks.
