fix & tool: enhancement for this integration

[junfengP]

1. In 2024/09/21, my Z7X projector is no longer listening on port 554, so the method I used to check its status is no longer working. I have scanned all the ports on my projector. Here is the result from nmap:

PORT     STATE SERVICE        VERSION
7001/tcp open  afs3-callback?
7002/tcp open  afs3-prserver?
7100/tcp open  font-service?
8080/tcp open  http-proxy?

I also found that when the projector is on, I can see its IP address in the router. This IP address disappears when the projector is off. Therefore, another way to detect the projector's status is by using the ping method.

2. I added a script tool for scanning BLE tokens; this simplifies the process of finding tokens.

I hope these corrections help clarify your message. If you need further assistance, feel free to ask!
