OK, so I've been snooping around and found this info from the Moto mod developers site:
https://developer.motorola.com/explore/software/mod-management
as well as this from tasker's literature:
https://tasker.dinglisch.net/userguide/en/intents.html
-specifically: "Tasker can only receive intents which are sent to broadcast receiver components, not to activities or services."
I've tried several of the intents from the Moto mods developer page in the tasker intent receive event edit, but I'm not coming up with the right combination to elicit the notification I have programmed in the profile. I'm not even sure if tasker is capable to trying to detect the Moto mods this way at all (broadcast receiver vs action vs service).
This is the part of programming that always gets the better of me. I really don't know enough to make any real progress in Java based android coding. Every now and again I can find something somewhere that helps me get by, but in this case, I'm really just guessing as to what goes where. If anyone can shed any light, I'd be more than happy to learn.
