Suppose I can send the desired amount to the device by sending a specific command. How can I detect in B4J which USB port the device is connected to and how do I send the command to the USB port?

nima66 Member Dec 3, 2024 #4 Sorry, I mistakenly said USB port I meant LAN cable. The device has an IP. So I probably need to connect to the device's IP with the socket library and send a message to it Upvote 0
