Hi all, We are trying to use Zephyr (https://www.zephyrproject.org) nrf52 hci example as BLE scanning device. We were able to sucessfully run the example according to this tutorial: https://devzone.nordicsemi.com/blogs/1059/nrf5x-support-within-the-zephyr-project-rtos/ We've successfully set up and communicate with Zephyr based controller using ubuntu 16.06 with kernel 4.8.0 and newest bluez release. Unfortunately our target final design is using embedded linux with quite old kernel (3.10.93). On this kernel, latest bluez release lacks btmgmt interface used in the example above. We are trying to use legacy tools like hciattach, hciconfig, hcitool to run scanning on nrf52 with zephyr hci example. After running: $ hciattach ttyACM0 any -s 1000000 flow we can see new hci device as: hci0: Type: BR/EDR Bus: UART BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 DOWN INIT RUNNING RX bytes:0 acl:0 sco:0 events:0 errors:0 TX bytes:8 acl:0 sco:0 commands:2 errors:0 Unfortunatelly we cannot get interface 'up' ./hciconfig hci0 up Can't init device hci0: Cannot assign requested address (99) so we cannot also start scanning ./hcitool -i hci0 lescan Invalid device: Network is down What I'm asking for is some advice on how to debug this problem and bring Zephyr based controller up. Thanks in advance, Jacek -- 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
