Ok, is this post related to the issue you sent me over DM? The device name is the same (“Switch”) and shows “checking” or “connected” because the capability “Switch” has no value as seen in this image:
You should see in the driver’s logs what’s going on (you need to use the logcat command of the ST CLI).
If there’s an error, you should be able to see it there, it shows the message exchange between the device and the driver and how they are being handled (Eg. converted to capability events)
Note: Also, per your description, you’re developing the Edge driver based on the parent/child scheme. Just as a reference, this should be used at your own risk. See my comment here
