Question
Which protocols is myQA Daily using to retrieve the information if the device/s are online?
Answer
When adding a device, myQA Daily is using the broadcasting functionality (UDP, port 5353) to list available devices in the same network sub net:
When the device is in a different hospital sub net than the server with the database, it is still possible to add the device manually (broadcasting is in most cases blocked for different network sub nets).
After having added the device, it will appear in the following list:
As myQA Daily needs an IP address and port to present this list, myQA Daily first try to locate the device in the list of online devices which is created by the broadcast protocol mentioned above (UDP, 5353).
Should myQA Daily not see the device with the broadcast functionality, myQA Daily will use the IP address and TCP port that is configured in the application (usually TCP, port 1338).
So, also when device and server are in different hospital sub nets, the user is able to see if the devices are online after having them set up initially.
