HE910 DSR signal

  1. Hi all,

     

    On my HE910, when module start, DSR rise HIGH during 500ms and fall down. Why ?

     

    I thought the DSR indicated the possibility to send commands, during all uptime.

    1. HE910 startup procedure (see Hardware User Guide) takes 5-6 seconds, and PWRMON should be checked for module’s status. One should not rely on DSR during startup.
