Note: Also tried with experimental features enabled in BlueZ

ubuntu@ubuntu:/connectedhomeip$ sudo systemctl edit bluetooth.service Editing "/etc/systemd/system/bluetooth.service.d/override.conf" canceled: temporary file is empty. ubuntu@ubuntu:/connectedhomeip$ sudo systemctl restart bluetooth.service

Still facing the same issue.

Extended advertising is disabled by default. In order to enable it you have to change these settings:

https://github.com/project-chip/connectedhomeip/blob/f658ea2f316cc0d4f1bdaae96ddd6be3d747a881/src/include/platform/CHIPDeviceConfig.h#L629 https://github.com/project-chip/connectedhomeip/blob/f658ea2f316cc0d4f1bdaae96ddd6be3d747a881/src/include/platform/CHIPDeviceConfig.h#L718

E.g.:

#define CHIP_DEVICE_CONFIG_BLE_EXT_ADVERTISING 1
#define CHIP_DEVICE_CONFIG_DISCOVERY_TIMEOUT_SECS (20 * 60)  // 5 minutes of extended advertising

@arkq After updating this config file the extended announcement is enabled. But test-plan expect that

DUT must send ADVs at a rate equal to 1200ms.

The following Advertising PDU payload fields shall comply with section 5.4.2.5.6. "Advertising Data". Verify that:

12-bit "Discriminator" field in Matter service data is populated

16-bit "Vendor ID" field in Matter service data is set to 0

16-bit "Product ID" field in Matter service data is set to 0

"Extended Data" bit is set to 1 if Extended Data exists otherwise set to 0 (Bit[0] of last byte)

"Extended Announcement" bit is set to 1 in Matter service data (Bit[1] of last byte)

But in all-cluster-app the ADV's rate is 1284ms which is out of range and the "Extended Announcement" bit needs to 1 but i got the 2 from the 16-bit data.

So this make the test-step to fail , Please correct me if my understanding is wrong
