| HTTP client problem |
 Posted: Thu Jun 01, 2017 9:10 am |

I'm using PIC18F97J60 with internal ethernet. I use my device as a client, it has the function of updating the sensor data and sending it to a server. I have been successful in sending data to the server. The server got the data and displayed it on the screen. The problem I encountered was that I could not change the data submitted. I can only send the initial default value when creating the project.
This is my entire main program.
Looking forward to receiving the help of all of you.
Thank you very much!
