ge865 serial port2

2 thoughts on “ge865 serial port2

  1. Hi,
    I am using the ge865 on a sparkfun evaluation board where I can find tx_aux and rx_aux , which I assumed I could send/receive data from my serial port device (sensor 2 pins only, flow control off)
    e.g. python script – ser2.send(), ser2.read().
    Now trying for a couple of days with all sorts of speed settings etc. I can;t get it to work.
    Do I need to switch it on somehow or are there certain conditions when I can use it?
    Has this anyting to do with mux – I guess I leave it as it is by default?
    serial port1 e.g. ser  is used by  usb adapter on evaluation board and I would like to keep this going as I can easily upload python files, debug or sent at commands from pc.
    I am writing files with notepad and upload with manually.
    Any help would be appreciated.

    thanks

    (if this is relevant I use GPRS  sending at  commands to MDM e.g.:
    AT+CGDCONT=2,"IP","www.vodafone.net.nz"r’,0,20,10,1,’OK’
    AT+CGQMIN=2,0,0,0,0,0r’,0,20,10,1,’OK’
    AT#SCFG=2,2,256,300,900,50r’,0,20,10,1,’OK’ 
    AT#SGACT=2,1r’,0,50,10,1,’SGACT’ 
    AT#SD=2,0,5001,"218.185.225.181",0r’,0 
    Connection and communication scripts via gprs works fine )

    1. GE865 has 2 serial ports:
      •  MODEM SERIAL PORT 1 (Main, ASC0)
      •  MODEM SERIAL PORT 2 (Auxiliary, ASC1) 

      Hardware User Guide doc gives info on this, including balls layout, voltage level translations etc

      The default SER2 speed (ASC1) is 9600.
