Bluetooth: Multiple Broadcaster


A simple application demonstrating the Bluetooth Low Energy Broadcaster that uses multiple advertising sets functionality.

This sample advertises two non-connectable non-scannable advertising sets with two different SID. Number of advertising sets can be increased by updating the CONFIG_BT_EXT_ADV_MAX_ADV_SET value in the project configuration file.

When building this sample combined with a Bluetooth LE Controller, the advertising data length can be increased from the default 31 bytes by updating the Controller’s CONFIG_BT_CTLR_ADV_DATA_LEN_MAX value. The size of the manufacturer data is calculated to maximize the use of supported AD data length.


  • A board with Bluetooth Low Energy with Extended Advertising support.
