PostRecordedData is:

msg.payload = "postRecordedData";
msg.headers = {};
msg.headers['statusCode']='200';
msg.headers['Server']='100.0.0.75';
msg.headers['Content-Type']='application/octet-stream';
msg.headers['Content-Length']='0';
msg.headers['Connection']='keep-alive';
msg.headers['X-Content-Type-Options']='nosniff';
msg.headers['X-Tandd-Next-Command']='none';

return msg;

What's wrong, because I have message from Base Unit that not success

You currently have an HTTP Request node in your flow. That is used to send http requests to a server.

In this case, you are trying to respond to an HTTP Request that has been received by the HTTP In node. You should use the HTTP Response node to do that.

like that?
