5.6. Feedback levels

Three feedback levels can be defined:

level

description

basic

The default feedback level. Only the reception point and the first following point are covered. Any

following events, including error events will not be reported.

most

This level covers most of the events, including error events. The only event excluded is the stop

event, which can take a long time to occur. This level informs about all possible problems, without

having to wait for the template instance to be actually stopped.

full

This level covers all events, including the stop event.

5.7. Enabling feedback

To enable feedback for one of the supported NRE sub commands, follow these steps:

1. Add the

fb-sw=true

field to the NRE command.

2. Optionally add the

fb-lev=xxx

field/value pair to the NRE command, where

xxx

defines the

actual feedback level as described above. When not added, nexos will default to

basic

feedback

level.

3. Add the exid=yyy field/value pair to the NRE command, where yyy represents a unique ID that

allows the initiator to link feedback messages and commands.

4. Communicate with nexos over a socket link and stay connected, waiting for feedback messages

from nexos.

If these conditions are met, nexos will send feedback replies over the socket link used for sending

commands. Feedback messages are returned as an updated 'echo' of the original NRE command,

enhanced with one or more fields generated by nexos, as described in the following section.
