Advertised Services Do Not Show In Packet 5.55 #189

Open zer0stars opened 11 months ago

Hello,

I have a problem with setting services that should show up in bluetooth advertising packet. Tried to shorten the length and manually add just 1 service, but unfortunately not working for me. Added btmon logs as well.

Setting the service manually by using sudo hcitool -i hci0 cmd 0x08 0x0008 12 11 07 30 44 5a 3e 35 50 0f ab 01 48 fd 25 11 63 a7 f5 00 00 00 00 00 00 00 00 00 00 00 00 00 makes it work. However I notice that the commands executed are different. Instead of 

< HCI Command: LE Set Advertising Data (0x08|0x0008) plen 32                                                                                                                                                                  #99 [hci0] 153.277241

It runs
