CAN Bus data is not appearing in the applications or tablet

This is by far the most common issue that we experience with the code and is unfortunately due to the nature of CAN Bus and particularly Windows OS.

CAN Bus is based on the UDP protocol, which is fire and forget and does not guarantee delivery, as such the packets often get ‘lost’. The best solution we have generally found to this is to disable any network adapter that is not required to run the system, this is particularly critical in a race environment. Ideally your PC and tablets should only be connected or able to connect to one network which is tested and you know works.

To do this in Windows find your Network Connection and disable anything that is not required. For example below this PC has both WiFi, Ethernet 5 (which is actually a docking station ethernet connection via USB) and Ethernet 2 a TAP or VPN connection. Having all these connections running increases the chance that you UDP traffic is coming down or going up the wrong link. Be careful disabling vEthernet connections as these are part of Docker and are required for it to run.
