3You see I want to broadcast data, not to send it to a certain one. – abrutsze Aug 24 '17 at 06:05

What you mean by broadcast? – Vygintas B Aug 24 '17 at 07:28

I am broadcasting "Hello" from device A and other devices without connecting to A getting that message. How I know all BLE ( like rangefinder, termometer, ... ) works in that way. I mean you can read the data without connecting to BLE. – abrutsze Aug 24 '17 at 07:34
