Project #007: BLE Peripheral and Broadcaster - Changing GAP Roles

Today's project is an interesting demonstration of how you could change the GAP role of a BLE device on the fly.

Recall, BLE devices can assume the following GAP roles:

  • Peripheral: Advertises capabilities and establishes connections with Central devices.
  • Central: Scans for advertising devices and establishes connections with them.
  • Broadcaster: Only advertises capabilities, does not connect.
  • Observer: Only scans for advertisements, does not connect.

There's also the possibility of a dual-role where the BLE device can be a Peripheral + Broadcaster

The BLE Component is configured with a custom Profile assuming the GAP Peripheral role. Once this Peripheral connects to a Central device (e.g. a mobile phone), it changes roles and begins to act as a Broadcaster. Other BLE devices in the vicinity can then see advertisement packets from this Broadcaster.
