    UART enable on Intel edison

    Radhika.k

      Hi,

       

      I'm working with SIM 900 on Intel edison arduino expansion board.To enable the UART I'm running the script file which is pinned below.Sometimes it is enabling the UART and sometimes it is not.When I run the script file and UART is enabled the voltage at Rx and Tx pins are 5.0 V .But sometimes even though I run the script ,UART is not enabling ,then the voltages at Rx and Tx pins are 0 V and 5V respectively. What is the reason behind this?? Can you please let me know the way of enabling the UART when the script file runs.

       

      Thanks and Regards,
