Hello, the UUID represents the "type" of data you want to send/ receive; if you're using serial, there is a standard UUID set up for that (should be in the example code). I don't know the specifics of the module you're mentioning, but if it works with the Serial Terminal application, it should work with this plugin.

You can see the screeshot of error I have taken from the android app I mention the link from play store.

this is bluetooth module attached on the pcb I have.

and this is uuid used in the example folder app
"00001101-0000-1000-8000-00805f9b34fb"

If the device communicates using serial, the provided UUID should work fine. I hadn't seen the first screenshot you had sent; check if the device appears in the phone's Bluetooth settings app. If not, check that the device is in pairing mode when connecting to it using the plugin.
