Rolling back since soundbox should anyway move to a microcontroller-based solution. 2024-09-29T09:17:53Z xengineering me@xengineering.eu 2024-09-29T08:56:44Z urn:sha1:97148c8d1b91289b1c41d736077fca8ac1a840d3 2024-09-29T09:16:30Z xengineering me@xengineering.eu 2024-09-29T08:53:57Z urn:sha1:c4611a3fbefdbc974b384ca71133e2e6fbc98240 It used to listen on IPv4 requests only. 2024-09-28T20:53:37Z xengineering me@xengineering.eu 2024-09-28T20:53:37Z urn:sha1:77158b80a0e3d24ec7c70a1ad36b1f680c942940 This board is suitable to connect passive speakers to an unofficial soundbox build. 2024-09-28T20:17:04Z xengineering me@xengineering.eu 2024-09-28T20:17:04Z urn:sha1:afa22db1f3a1b50b6ae9577df8da7af830047601 2024-09-28T20:09:46Z xengineering me@xengineering.eu 2024-09-28T20:09:46Z urn:sha1:55db6f8b7338a2c47447aceec93908160dd60128 It is a bit more complex to stream via IPv6 link-local addresses.

Thus a label containing the MAC address has to be added to the device. 2024-09-28T19:49:08Z xengineering me@xengineering.eu 2024-09-28T19:12:34Z urn:sha1:844588c7b98db65fc4c8050bae3184a747822092 The MAC address is required to compute the IPv6 link-local address of the device used for streaming audio. 2024-09-28T19:49:08Z xengineering me@xengineering.eu 2024-09-28T18:51:04Z urn:sha1:7745d56644621cb0365d51ee5a284a36f5089dd6 soundbox should use IPv6 for streaming. IPv6 link-local addresses are well-suited for soundbox devices since they are generated by the hardware MAC address in this case. This has the advantage that they do not need external infrastructure like a DHCP server to be set up and that they are valid and unique for the whole life cycle of the device. This makes network management significantly easier. 2024-09-28T19:49:02Z xengineering me@xengineering.eu 2024-09-27T13:59:53Z urn:sha1:6cfb69f8a265ffadead2275c13c74178b17b5184 The goal is to switch to IPv6 link-local addresses only. They have the advantage that they can be static by a hardware MAC address, are suited for local network streaming and discovery can be done by using the `ping` utility. Additionally the address can be calculated based on MAC addresses which can be printed on the case and typed into the client by the user. Thus this makes network discovery only a convenience feature instead of a required one. Removing the LLDP-based discovery is the first step into this direction. 2024-09-28T19:48:48Z xengineering me@xengineering.eu 2024-09-28T17:56:30Z urn:sha1:0abe275743dd9cf73e339a7e41636a6da0f7914f No special reason for the update.

This is not intended.

Thus it can be applied to all contents of this repository. Having only one license makes the license structure for this project way easier. Since the OHL is written with hardware in mind it likely fits better to this open hardware project. 2024-01-31T20:34:17Z xengineering me@xengineering.eu 2024-01-31T20:34:17Z urn:sha1:0c1cabb24ed00c6a69a69cc4bc4505c384be6b35 This makes sure that the version / date file is always re-generated.
