mqtt-publisher

Hi all,
I experimented with the mqtt-publisher on a trial basis. It works well so far, but I can't publish more than 10 HAL pins. Even if there are more than 10 parameters under keys=, only the first 10 are transmitted. Does anyone know if I'm doing something wrong? I followed the mqtt-publisher instructions exactly.
Thanks for help
Peter
 

Did you notice the bit where each token is limited to 255 characters and to get sound this you can use multiple "keys" entries ?

It's hidden in under the examples heading.
If you have no further luck it may be of interest to raise an issue on the GitHub page.

When I create multiple “keys=” entries one below the other, LinuxCNC no longer starts:

Try this for the keys

I see what you mean, even when it starts with multiple key entries only the last group of keys get sent

With your settings, I only receive 7 values. 

After removing the axes and joints that are not present on my milling machine, the result is the same - only 7 values are received. Sorry, I don't understand the principle of keys entries.

I have now shortened the list to 9 entries and am only using one key= statement. This allows me to transfer all 9 values.
loadusr -W mqtt-publisher \
--mqtt-broker=[MQTT]BROKER --mqtt-user=[MQTT]USERNAME \
--mqtt-password=[MQTT]PASSWORD \
keys=halui.axis.x.pos-relative,halui.axis.y.pos-relative,halui.axis.z.pos-relative,\
halui.joint.0.is-homed,halui.joint.1.is-homed,halui.joint.2.is-homed,\
halui.estop.is-activated,halui.machine.is-on,halui.program.is-running \

Like I said it may be worth raising an issue on GitHub as the actual behaviour does not match the behaviour in the docs.

yes, you are right. I'll do it.
