bad data over tcp

9 thoughts on “bad data over tcp

  1. Hello 


    Recently my test device sending giberish data over tcp. it is like random characters.


    I am using GE-865-quad, a server listens for connections and devices registers themselves to the server. There are devices working good with same software.  


     what may be the problem?


    Thank you 

      1. I changed python software to send data to my computer and i listened the port with hyper terminal. Device send bad data again. Then i tried same software with another device it sent decent data. So my conclusion is problem is on my device. And i suspect there are bad sectors at device’s ram or tcp buffer or something


        is it possible? 

          1. Problem solved after flashing module. Since i go in trouble flashing i upgraded it to 10.006. Now it sends decent values. 

            My new question what behaviour may cause bad firmware so i can avoid them

          2. Sorry i misunderstood; 

            Sudden power losses are because of development process. 
            There is no sudden power loss during test process
