Android Question How mobile app control garage door?

[Adamdam]

Dear all,
greetings,
I need to build controller on mobile to control garage door,
If I use Bluetooth take some time to start communication with Bluetooth module, it requires to authentication between mobile a Bluetooth module. how to overcome this step? it takes long time.
I need fast operation, even by Bluetooth or Wi-Fi,
I read about BLE, as I stood it does not require authentication or any long time, correct me please, if yes, I need project (B4A +B4R or Arduino)
hope for correction, and help if can
Best regards

Hi all: *** ADDED Project with B4XPages working on B4A and B4J. See post #15 Not sure if this is the rigth place, or if I should publish it in Examples, @Erel, feel free to move. The code is not perfect, but it works. Most of code is copied/pasted/modified from forums, so this app is made by...

Look for wifi relay on Ebay. Even better, look for ones that also have some switch inputs (eg roller door limit sensors) as well as relay outputs.

If you open up a punch-through port on your home router to the wifi relay board, then your app can talk to the garage door relays via internet.

You might even be able to communicate with the relay board via wifi directly, without needing a router to glue the two ends together.

fast? then use a RFID Reader 6mts or 12mts Long Range and a passive tag

You can configure the BLE module in advertising mode, enabling quick connections, though not as instantaneous as simple RFID
