BGS5T input GPIO allways 0 | Telit Cinterion IoT Developer Community

I am trying to read GPIO input states trough java and terminal, but I am allways getting 0, even when there is 5V on that input.
Terminal code:
AT^SPIO=1
AT^SPIO=1
OK
AT^SCPIN=1,6,0
AT^SCPIN=1,6,0
OK
AT^SCPIN=1,7,0
AT^SCPIN=1,7,0
OK
AT^SGIO=6
AT^SGIO=6
^SGIO: 0
OK
AT^SGIO=7
AT^SGIO=7
^SGIO: 0
at^scpol=1,7
at^scpol=1,7
OK
at^scpol=1,6
at^scpol=1,6
OK
Java code:

protected void startApp() throws MIDletStateChangeException {
InPort5V inport = null;
OutPort5V outport = null;
try {
m_Cmd = new ATCommand(false);
m_Cmd.addListener(m_Listener);
String Response = m_Cmd.send("-AT+CMEE=2\r");
System.out.println(Response);
Response = m_Cmd.send("ati\r");
Vector pins = new Vector(1);
pins.addElement("GPIO21");
inport = new InPort5V(pins);
inport.addListener(new gpioListener());
} catch (IOException e) {
e.printStackTrace();
} catch (ATCommandFailedException ex) {
ex.printStackTrace();
}
catch (IllegalStateException ex) {
ex.printStackTrace();
} catch (IllegalArgumentException ex) {
ex.printStackTrace();
}
int a = 0;
boolean run = true;
System.out.println("Inport : " + inport);
while (run) {
a++;
if(a > 20)
{
try {
inport.release();
} catch (IOException ex) {
ex.printStackTrace();
} catch (OperationNotSupported ex) {
ex.printStackTrace();
}
destroyApp(true);
run = false;
}
try {
Thread.sleep(4000);
System.out.println(inport.getValue());
} catch (InterruptedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
destroyApp(true);
}
}
I tryed all the GPIOs : 6,7,8, 20, 21
AT^SCFG returns this, as I watched the data sheet everything is ok.
AT^SCFG?
AT^SCFG?

Tnx fpr your help
Hello Jedrzej
It worked for me also.
Can you tell me the same for the rest of GPIO !!. It is, What SSPI command to use to set as inputs?.
Hello,
To set as inputs please send in the same way as described by Jędrzej:
GPIO6 <aD41000>
GPIO7 <aD41100>
GPIO8 <aD41200>
GPIO11 <aD41300>
GPIO12 <aD41400>
GPIO13 <aD41500>
GPIO14 <aD41600>
GPIO15 <aD41700>
GPIO21 <aD41800>
GPIO20 <aD41900>
You can find all details in BGS5T Hardware Interface Description.
Regards,
Bartłomiej
