Android Question Connect to BLE when no pair is needed

[Shay]

Hi
I have BLE device that does not require any pairing
I need to connect to it and read/write data to it
with BLE scanner (app store) I can see it and connect and read/write
with BLE2 I cannot do it

How can I do it?
Thanks

They are library files, put them to additinal folder of B4a.
