      Hi,

      could you give me more info:

      module setting 

      are you using Telit demokit or your application?

      are you using flow control?

      test description

      Thanks

2. sure modul setting (register nr = setting )

   Cordinator:

   202=7

   214=255

   306= 2

   307=3

   310=42

   315=48

   316=48

   320=148

   321=17

   322=0

   323=4

   324=11

   330=2

   332=1

   333=0

   340=0

   345=0

   346=0

   347=0

    

   My system consists of 5 units, 1 cordinator and 3 endpoint + 1 endpoint/router.

   Each endpoint makes one packed of data every 10 sec, and transmits it to the cordinator, the cordinatoer never sends anything, only resives. the resived serial data going into a computer.

   Im using Flow control but since that system only sendes to a computer i doubt that is the problem, and to fix my problem i only have to reset the cordinator.

   Thanks for the help:-)

   1. Hi,

      how many data you sent every 10 sec? 

      which is Router setting? did you try to increase base time and super frame duration?

      1. each endpoint sends 1 packed of 105bytes, every 10sec, they are not synced individual so that they don´t all send at the same time.

          

         Router have same setting as cordinator.

          

         Have not tried to increse the super frame duration.

         1. Hi,

            I created a network with 

            1 coord

            3 router.

            I’m using default setting.

            I changed only:

            ATS214 (SET TO 255) and payload (ats330=2

            I’m sending a package of 110 bytes and Coord works well.

             

            Could you try the same my setting please?

            1. Hi

               i can try that but how do i change that with the network running, getting to each of the radio moduls is hard:-( 

               but if i change it it will take 4-6 weeks to get the result.
