BLE without connection

Postby awaisahmed » Thu Jul 19, 2018 6:12 am

if someone has read the kolban ESP32 book in BLE section on page 196 its written that

peripheral can simply broadcast its packets of data and the central can receive them
without the need to form a connection.

how this can be achieve ?

Try to find some info about beacons. Beacons are peripheral devices that only advertising some data and are not connectable.

You need to read a little about how iBeacon connection works..

P.S. all you need to know is the Bluetooth role, advertising packet and scan response :)
