Hi Luiz, I tried with 2 BT 4.0 dongles both of which have the same problem. And instead of running example-advertisement, if I run the following commands 2 commands manually, it works fine and I can discover and connect to my device: hcitool -i hci0 cmd 0x08 0x0008 3 02 01 05 hciconfig hci0 leadv So I only have problem with the dbus advertising api. Copying the commands and output from btmon below. example-advertisement does not seem to set and advertisement data at all. //Run example-advertisement < HCI Command: LE Set Advertise Enable (0x08|0x000a) plen 1 [hci0] 7.258091 Advertising: Disabled (0x00) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 7.259431 LE Set Advertise Enable (0x08|0x000a) ncmd 1 Status: Success (0x00) < HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15 [hci0] 7.259540 Min advertising interval: 1280.000 msec (0x0800) Max advertising interval: 1280.000 msec (0x0800) Type: Connectable undirected - ADV_IND (0x00) Own address type: Public (0x00) Direct address type: Public (0x00) Direct address: 00:00:00:00:00:00 (OUI 00-00-00) Channel map: 37, 38, 39 (0x07) Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 7.260346 LE Set Advertising Parameters (0x08|0x0006) ncmd 1 Status: Success (0x00) < HCI Command: LE Set Advertise Enable (0x08|0x000a) plen 1 [hci0] 7.260444 Advertising: Enabled (0x01) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 7.261344 LE Set Advertise Enable (0x08|0x000a) ncmd 1 Status: Success (0x00) //hcitool -i hci0 cmd 0x08 0x0008 3 02 01 05 < HCI Command: LE Set Advertising Data (0x08|0x0008) plen 4 [hci0] 288.328182 invalid packet size 03 02 01 05 .... > HCI Event: Command Complete (0x0e) plen 4 [hci0] 288.329444 LE Set Advertising Data (0x08|0x0008) ncmd 1 Status: Success (0x00) //hciconfig hci0 leadv < HCI Command: LE Set Advertising Parameters (0x08|0x0006) plen 15 [hci0] 343.872012 Min advertising interval: 1280.000 msec (0x0800) Max advertising interval: 1280.000 msec (0x0800) Type: Connectable undirected - ADV_IND (0x00) Own address type: Public (0x00) Direct address type: Public (0x00) Direct address: 00:00:00:00:00:00 (OUI 00-00-00) Channel map: 37, 38, 39 (0x07) Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 343.872852 LE Set Advertising Parameters (0x08|0x0006) ncmd 1 Status: Success (0x00) < HCI Command: LE Set Advertise Enable (0x08|0x000a) plen 1 [hci0] 343.880238 Advertising: Enabled (0x01) > HCI Event: Command Complete (0x0e) plen 4 [hci0] 343.880842 LE Set Advertise Enable (0x08|0x000a) ncmd 1 Status: Success (0x00) On Thu, Jul 9, 2015 at 2:45 PM, Luiz Augusto von Dentz <luiz.dentz@xxxxxxxxx> wrote: > Hi, > > On Thu, Jul 9, 2015 at 3:15 PM, dogan yazar <doganyazar@xxxxxxxxx> wrote: >> Hello, >> I am using Bluez 5.32 on kernel 4.1. >> >> When I run advertisement-example, bluez successfully sends >> advertisement but then as an answer to scan request it sends an empty >> scan response. >> >> Any idea what can be the problem? > > Could you please add the trace, iirc BlueZ only set the scan data so > it is up to the controller to generate the scan response not the host > stack so perhaps there is something wrong with your controller. > > > -- > Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
