| 51 | This error is printed by {{{wl_initNodes}}} when it is able to communicate with individual nodes, but nodes failed to receive a trigger packet. |
| 52 | |
| 53 | Things to check: |
| 54 | * Are all WARP nodes and the host PC on a common Ethernet switch? |
| 55 | * Is the host PC NIC IP address in the same subnet as the WARP nodes (10.0.0.x by default)? |
| 56 | |
| 57 | Debug steps: some PCs require a manual ARP table entry to allow broadcast IP packets. On Windows, open a command prompt as an admin user and run {{{arp -s 10.0.0.255 ff-ff-ff-ff-ff-ff}}}. Run {{{arp -a}}} to confirm the new entry was accepted. The output should look like: |
