The manuals assume a v0.1 release. We should create one.

If the first release is not named v0.1 the following documents need updating:

• ethmux-M01
• lxatac_can_io-M01

The TROUBLESHOOTING.rst file is no longer present in the repo.
We should remove the reference to it and replace it with a link to this URL:

• https://lxa-iobus.readthedocs.io/en/latest/troubleshooting.html

I used pip install -e .[server] to install only the server portion, however this does not lead to a usable web interface.
Executing the Makefile used [full] which leads to a working server environment. Either [server] should be removed or fixed to provide a working server.

LXAIOBus nodes tend to be left in "locate" mode making it impossible to locate a new node. The locator function must be turned off manually, either via the web interface or with the button on the LXAIOBus. Only after that, the locator mode is useful.

When activating the locator mode on a node, it should time out after a few minutes (10? 30?).

There is a new SDO endpoint SERVER_TIMEOUT_SDO (0x2d06) that, when set to 1 enables a watchdog mode in the node firmware.
When enabled the node will reset its node_id after not being pinged for some time, so that it can be re-discovered via LSS.

I would go about implementing this feature like this:

• Break out the discovery of supported SDOs from LxaNode::get_info() into a separate method (maybe also cache the results)
• Check the supported SDOs early in the node discovery
• Enable SERVER_TIMEOUT for nodes that support it as early in the node discovery as possible
