leaving transparent mode with DTR line toggling unreliable | Thales IoT Developer Community

Our scenario is that we enter transparent **** to a server, send some data and close transparent **** to communicate with some other host, etc. We use DTR line toggling to escape from transparent ****. Now it seems that *some****** the ****m becomes unresponsive after toggling the line. My assumption here is that the ****m either some***** stops/halts or transparent **** remains on. Any idea which? The symptom is that issueing a command such as ATI in the error case does not respond *at all*.
- Is there a guidance for how long we should keep the DTR line high?
- it seems more reliable if we toggle the DTR line multiple *****? Is this true?
Note: ATI1 gives: Cinterion||PLS8-E||REVISION 03.017||A-REVISION 01.000.05||||OK in the normal case.
