Sending and receiving data/text over bluetooth without paring

[imrpk]

Hi,
I am looking for support or sample for sending and receiving data/string/messages between each others (windows, IOS, Android & RPI) over the blue tooth but without paring but all these devices have installed application accordingly B4J, B4I, b4A & b4R

I think @Peter Simpson updated a BLE server peripheral library that should enable this.

This feels like it:

Customise your BLE GATT Service with BLE Peripheral 2 Enhanced

Hello All, First I want to say thank you to the B4X developers that reached out to me via PM and to others that I spoke to, you all know who you are ? As you are all well aware I personally do not touch Java, I only started learning java so that I could enhance Erel's current BlePeripheral2...

www.b4x.com

and the specific bit you'd be using to send information is:

Properties:

• ManufacturerData As Map
  Gets or sets the manufacturer specific data that will be advertised.
  Each item in the map should have a positive int number as the key and an array of bytes as the value.

which other devices the receive via the BLE2 scan for available devices.
