Like many others in this forum, I am trying to get unsolicited messages from the zip gateway. I have followed the “Instant Success” Guide with the referenced Raspberry Pi 3 image and have gotten completely through it for the reference_client. It would have been useful if the guide included the reference_listener because that is where I (and, apparently, many others) have had difficulty. I saw only one thread that resulted in receiving messages (Zip reference server/listener), but the posted configuration did not work for me and I’m not even certain that the author of the post used the same Raspberry Pi 3 image.
I’ll continue to troubleshoot my set up, but I’d appreciate it if someone could assure me that the current Raspberry Pi 3 image actually contains a working reference_listener (I’ve already verified the reference_client).
