Hi Marcel, >> I’m running BlueZ 5.50 on my embedded platform containing an ODIN-W160 WiFi/Bluetooth-combo-chip with a TI Bluetooth core. After un-resetting the Bluetooth power GPIO, I run `hciattach … texas 115200 flow` and then start bluetoothd. In `main.conf`, I have set `Privacy=device`. >> >> With this setup, the `set_privacy_complete` (adapter.c) callback in bluetoothd is called with `status == MGMT_STATUS_REJECTED` and according to my 4.9 kernel, this is the case when `hdev_is_powered`: After booting and running `hciattach`, my chip is already "up" and thus I cannot set the IRK. >> >> I found in `texas_post` (hciattach_ti.c), that there's an explicit ioctl to HCIDEVUP the chip at the end, so this combination cannot work correctly at the moment. >> >> For the time being, I have extended my hciattach systemd unit with `ExecStartPost=/usr/bin/hciconfig hci0 down` and that fixes the `set_privacy` call chain when starting bluetoothd. > > stop using hciattach and start using serdev. I'm still on linux-stable 4.9, so I have to put that on the list of things that will be better when I find time to update. Thanks for the pointer!
