Hi, I'm attaching a Zephyr based Bluetooth controller that exposes an hci interface. To make the Linux host part understand the controller i run: ~# sudo btattach -B /dev/ttyACM0 -S 1000000 I can see messages being exchanged in btmon but eventually it ends with the following error: = bluetoothd: Failed to open crypto 3.879748 = bluetoothd: No Bluetooth address for index 0 [hci0] 3.879916 Am assuming two things here: 1. The underlying embedded device doesn't have the appropriate crypto hardware. This results in errors when trying to open an crypto socket. I've enabled all the crypto related settings in the kernel config. 2. The only thing crypto is used here is to generate the address for the controller, but besides that isn't essential. Is there a way to disable the crypto dependency, generate it in software or set the address manually? -- 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
