Hangs at connecting to smart device wifi

[interfect]

When I try to use the app on my Jasco Enbrighten WFD4105E (with the Tuya CB2s featuring the BK7231N), it hangs at the step of connecting to the device.

I get a log like this:

It seems to be trying to scan as fast as possible and hitting the wifi scanning rate limit as noted here.

A workaround may be to disable wifi scan throttling in the developer options, but if it is possible to work within the throttle the app should detect if it is being throttled and slow down/back off on the scans.

Turning off the limit in my device's developer options worked around this issue.

I was able to dump the firmware with the "Type 1 / Addr 1" profile.

Here it is for reference: dump_wfd4105e.zip

I will see about getting it to the proper place to make a profile for the flasher tomorrow.

Added a profile to CloudCutter for this plug.
