Is WiFi required for the SDK to operate correctly?

[bbenson09]

My app crashed yesterday mid-flight with nondescript error messages (suggesting it might not have originated in my code), and I'm trying to understand what happened. I was operating in very low bandwidth conditions.

All I have is:

--------- beginning of crash
10-24 17:32:30.312 19984 19984 E AndroidRuntime: FATAL EXCEPTION: main
10-24 17:32:30.312 19984 19984 E AndroidRuntime: Process: com.mypackage.name, PID: 19984

However, I noticed that the following lines came directly before the crash in my logs:

10-24 17:32:30.102 19984 20132 E DJIUSBWifiSwitchManager: ****resetSwitchFromWifiFlag

10-24 17:32:30.275 19984 20072 E DJIUSBWifiSwitchManager: ****resetSwitchFromWifiFlag

I was operating in poor WiFi conditions yesterday, and I'm wondering if it's a coincidence that the DJIUSBWifiSwitchManager was doing some operation just before the crash.

What is the likelihood that the DJIUSBWiFiSwitchManager would have caused a crash if it wasn't able to connect to WiFi?

Thanks.

The WIFI is not required, Normally, the SDK requires network to register, once it registers you can fly without network.
