Hello, I am running the Zephyr BLE Controller described https://devzone.nordicsemi.com/b/blog/posts/nrf5x-support-within-the-zephyr-project-rtos and I can't bring up the hci interface. sudo hciconfig hci1 up Can't init device hci1: Cannot assign requested address (99) This is the same issue as described here https://www.spinics.net/lists/linux-bluetooth/msg71100.html except I am running Raspberry Pi version 9.4 and bluez 5.50. hciconfig does show the device: hciconfig hci1: Type: Primary Bus: UART BD Address: 00:00:00:00:00:00 ACL MTU: 27:7 SCO MTU: 0:0 DOWN RX bytes:245 acl:0 sco:0 events:18 errors:0 TX bytes:103 acl:0 sco:0 commands:18 errors:0 btmon output during the hci up operation: @ RAW Open: hciconfig (privileged) version 2.22 {0x0005} 290.771000 @ RAW Close: hciconfig This bug from 2014 describes it as maybe not fixed in Raspbian - https://bugzilla.kernel.org/show_bug.cgi?id=60824 and https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=f9f462faa02777f497eb25255683a94e0c054de6. Is there a way to determine if it is included in the current version of Raspbian? The same board works fine when connected to a Ubuntu 16 system. Please let me know if there is more information I can provide and thanks in advance, Eric
