Eos TCP Packet not working

Question

Hello community folks, 
 
 I am working on developing a flutter application for eos control via osc. It is currently using udp, but I would like it to use tcp. 
 
 I have been trying to send a raw packet via packetsender and have tried commands like 
 - /eos/ping, 
 - /eos/ping 
 - /eos/ping\0\0\0\0 
 - /eos/ping,d 
 - etc. 
 I have also tried via ETCLabs osctester app but have had no luck. 
 I am able to send it with luminous thought, which makes me think there is something wrong with my packet. 
 
 I have also looked at the OSC Specification Examples and cannot figure out what I am doing wrong. any insight would be helpful.

OSC sent over TCP must be framed appropriately, either with packet length headers or with SLIP encoding. 
 Here is an example of the encoding in a simple open-source utility written in C++ (there are many other examples, but this is relatively succinct) OSCTester/src/OSCParser.cpp at master &middot; ETCLabs/OSCTester &middot; GitHub 
 You may also be able to use Wireshark and inspect the packets Luminosis is sending, to also see a working example.
