Hi, I'm trying to leverage the LE advertising API in BlueZ 5.31 but advertisement registration sometimes fails with an Invalid Parameters error: Jun 24 21:56:06 orion bluetoothd[21940]: src/advertising.c:register_advertisement() RegisterAdvertisement Jun 24 21:56:06 orion bluetoothd[21940]: src/advertising.c:advertisement_create() Adding proxy for /org/iotivity/gatt/advertisement0 Jun 24 21:56:06 orion bluetoothd[21940]: src/advertising.c:register_advertisement() Registered advertisement at path /org/iotivity/gatt/advertisement0 Jun 24 21:56:06 orion bluetoothd[21940]: src/advertising.c:parse_advertising_service_uuids() Adding ServiceUUID: ADE3D529-C784-4F63-A987-EB69F70EE816 Jun 24 21:56:06 orion bluetoothd[21940]: src/advertising.c:refresh_advertisement() Refreshing advertisement: /org/iotivity/gatt/advertisement0 Jun 24 21:56:06 orion bluetoothd[21940]: Failed to add advertisement: Invalid Parameters (0x0d) It looks like my LEAdvertisement1 object itself is fine since BlueZ doesn't complain about it. There are times when registration succeeds, as well. Adding an advertisement with the same data through the btmgmt tool will fail in the same way if I provide a bogus instance ID: [mgmt]# add-adv -c -g -u ADE3D529-C784-4F63-A987-EB69F70EE816 0 Add Advertising failed with status 0x0d (Invalid Parameters) but is fine if I provide a suitable instance ID: [mgmt]# add-adv -c -g -u ADE3D529-C784-4F63-A987-EB69F70EE816 1 Instance added: 1 As a sanity check I ran test/example-advertisement but it fails for other reasons: $ ./example-advertisement Failed to register advertisement: org.bluez.Error.Failed: Failed to parse advertisement The log output Jun 25 11:04:43 void-dev bluetoothd[758]: src/advertising.c:register_advertisement() RegisterAdvertisement Jun 25 11:04:43 void-dev bluetoothd[758]: src/advertising.c:advertisement_create() Adding proxy for /org/bluez/example/advertisement0 Jun 25 11:04:43 void-dev bluetoothd[758]: src/advertising.c:register_advertisement() Registered advertisement at path /org/bluez/example/advertisement0 Jun 25 11:04:43 void-dev dbus[793]: [system] Rejected send message, 1 matched rules; type="method_call", sender=":1.2" (uid=0 pid=758 comm="/usr/libexec/bluetooth/bluetoothd --experimental -") interface="org.freedesktop.DBus.Properties" member="GetAll" error name="(unset)" requested_reply="0" destination=":1.222" (uid=1000 pid=13905 comm="/usr/bin/python ./example-advertisement ") Jun 25 11:04:43 void-dev bluetoothd[758]: Failed to read "Type" property of advertisement Any ideas on what could be causing the intermittent advertisement registration failures when using the BlueZ D-Bus advertising API?
