Thanks a lot for the response Klaus_K.
The BLE Scanners are great, but just sending the digits/characters isn't great from UX point of view.
I was hoping to use something like MiT App Inventor, or something like that so at least i can build a semi nice looking app to use in the project. For those to work i need to pair the device (i think) with my phone.
Is there a workaround so i can use something like MiT App Inventor? (https://appinventor.mit.edu/)
