@jackmanjlskmv1xe, if you are not able to list device names still, Please see here. I was able to list device names. This was less than 1 hr of testing and trying different blocks. no tutorial used.
I first started by listing the names into a label. then by adding that list to a variable or an error to that label should one occur.
next i loop all items in the name list to make sure there is actual text there, apparently some devices transmit a signal without including a name. if name is null, set it as ‘no name’
then i displayed all names into a list viewer.
if you click on a list viewer item name, you will see the associated device id
