Hi thanks for indulging me. Wondering if this hearing aid streaming service can be implemented in the Linux bluetooth stack. So far only found in iPhone and some Android phones There is more information at https://source.android.com/devices/bluetooth/asha I would be happy to help with testing if anyone is interested. I have a Nucleus7 CochlearSpeech Processor and I can connect to it with this RPi4B running 5.4.71-v7l+ with bluetoothd v5.5 bluetoothctl v5.49 gives the following output: [bluetooth] [0m# list-attributes 84:77:XX:XX:XX:XX Primary Service /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075 0000fdf0-0000-1000-8000-00805f9b34fb Unknown Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char007f 2d410339-82b6-42aa-b34e-e2e01df8cc1a Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char007d 00e4ca9e-ab14-41e4-8823-f9e70c7e91df Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char007a 38663f1a-e711-4cac-b641-326b56404837 Vendor specific Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char007a/desc007c 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char0078 f0d4de7e-4a88-476c-9d9f-1937b0996cc0 Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0075/char0076 6333651e-c481-4a3e-9169-7c902aad37bb Vendor specific Primary Service /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064 3c3c6c6b-c9bc-4704-bb14-2ffd32b5aa31 Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0073 18e77d96-c2a2-4da9-a848-436a8aea81ba Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0071 8e5abd16-d6e0-4efb-8881-4d9d257b017a Vendor specific Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char006e 962020af-7715-4f77-b8db-b2ea0e89415b Vendor specific Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char006e/desc0070 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char006b 47c7e464-7bb4-4c8b-9515-3a2141b65300 Vendor specific Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char006b/desc006d 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0068 0472ca69-929b-44ad-9821-97078d06c362 Vendor specific Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0068/desc006a 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0065 31291857-6a7e-4b77-8655-feb603498758 Vendor specific Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0064/char0065/desc0067 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Primary Service /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a 0000180a-0000-1000-8000-00805f9b34fb Device Information Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char0015 00002a50-0000-1000-8000-00805f9b34fb PnP ID Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char0013 00002a26-0000-1000-8000-00805f9b34fb Firmware Revision String Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char0011 00002a27-0000-1000-8000-00805f9b34fb Hardware Revision String Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char000f 00002a25-0000-1000-8000-00805f9b34fb Serial Number String Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char000d 00002a24-0000-1000-8000-00805f9b34fb Model Number String Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service000a/char000b 00002a29-0000-1000-8000-00805f9b34fb Manufacturer Name String Primary Service /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0001 00001801-0000-1000-8000-00805f9b34fb Generic Attribute Profile Characteristic /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0001/char0002 00002a05-0000-1000-8000-00805f9b34fb Service Changed Descriptor /org/bluez/hci0/dev_84_77_XX_XX_XX_XX/service0001/char0002/desc0004 00002902-0000-1000-8000-00805f9b34fb Client Characteristic Configuration Cheers Peter Barrett
