To solve the issue, un-install and re-install Bonjour. Times to times, even if Bonjour is already installed on your computer you can't connect directly to your Ergo Jr. If you already have installed an Apple Software like iTunes or QuickTime, Bonjour should be installed. You have to install Bonjour print services for Windows (yes, it is an Apple software). Otherwise replace all poppy.local occurrences by the IP address of the robot given by your router. Zeroconf is not mandatory on your computer to use Poppy robots, but it is strongly recommended, and the documentation will assume it is installed. It makes able to connect the robot to your computer directly with an Ethernet wire without using a router, and without a DHCP server.It makes able to reach the robot on your local network without having to know its IP address.Zeroconf also called Bonjour (name of Apple implementation) or Avahi (name of Linux implementation), is a set of technologies that allow more easily communication between computers without configuration. Note that their might be different settings for iOS devices than for Mac OSX platforms.Ĭheck with the WiFi Controller provider for detailed information.Program with Jupyter notebooks on the real robot In some network environment Wireless Controller needs to be setup so that IPPS traffic is republished around the network. It is necessary to leave the NIC setup with IPV6 enabled even if this protocol is not effectively used on the LAN, then AirPrint announcements are properly done on the selected NICs. This is due to a bug in the JRE that prevents announcements to select the correct source NIC. However, one can notice that AirPrint announcements are not done properly from the selected source NIC. When the EveryonePrint Mobile Gateway is fitted with multiple NICs you can select which one(s) will be used to announce devices with the mDNS protocol. If a router (Cisco or equivalent) is used to route AirPrint mDNS traffic across multiple subnets, make sure to amend its setup accordingly, so that iOS devices see the AirPrint devices on each relevant subnet. In a multi-subnet network environment, the EveryonePrint Mobile Gateway can be setup to make AirPrint announcements on multiple NICs. This is not a problem as the iOS device will simply be forced to open a secured connection. Since EveryonePrint Mobile Gateway 4.1.0.1 announcements are done using secured _ipps._tcp. protocol, that is the recommended and preferred protocol since iOS 7. Prior to EveryonePrint Mobile Gateway 4.1.0, announcements are done with unsecured _ipp._tcp. protocol Install your distribution's package for ' avahi-utils'.Install your distribution's package for ' avahi-discover'.Apple iOS: Discovery - DNS-SD Browser:.Troubleshooting:Correct announcements of Gateway and printers may be checked using a "Bonjour Browser" tool available for your OS platform. It is also required for the service and printer announcements to work, that the iOS devices are on the same WiFi Network as the EveryonePrint Mobile Gateway. In order to discover the EveryonePrint Mobile Gateway and to see available printers on Apple iOS devices, it is required that there are no firewalls or routers blocking the gateway service and printer announcements from the EveryonePrint Mobile Gateway to the iOS devices on UDP port 5353 (Apple Bonjour protocol UDP port 5353 (Multicast DNS)). This article covers two different possible issues depending on installation type: The EveryonePrint server and EveryonePrint Mobile Gateway have been installed and configured, however it's not possible to see the AirPrint printers announced from an iOS device.
