Greetings,
I have some issues creating a stable connection between a mobile device (AGV) and a VM running a windows server OS (I would have to ask which version).
The wireless network, VM and main gateway are present and not something I can see the settings of.
The AGV is a vehicle able to freely drive around in a set area, it uses a number of ethernet devices to operate:
- Navigation controller, this is an VBox IPC running unix. It is the main controller of the AGV.
- IO controller, this is an Omron PLC, it is mostly intended to handle safety and status.
- Laser scanners, 2 laser scanners measure the environment for navigation and safety purposes.
- Wireless bridge, a HP Aruba 501 connects to an existing wifi for all communication.
The wifi has multiple APs that the bridge can connect to and it allows for roaming. the VM that the AGV needs to communicate with is on the same subnet as the AGV.
From time to time the connection seems ok, but it can drop at any moment and stay off for a seemingly random time. This is not a roaming effect as it can occur when stationary with a good connection to the network.
Network setup:
When pinging the AGV components from the server or service laptop only 1 device tends to respond. pinging another device long enough and you can often get a connection to the other device.
Similar setups have been created and they work but for some reason here it does not. what would be required to be able to access all network components at any moment? We test these devices with a setup where there are no seperate APs, the gateway is a router with wireless capabilities and then this works properly as well.
Without a good clue what is causing this odd behavior I cannot propose changes to either the bridge or gateway settings. Even a nudge in the right direction may be enough to help.
I do not have all the information, but I will answer any questions regarding more specific settings and/or devices if I can.
