How can I use UART and SoftwareSerial with TEL0051

Dear All,
I am still trying the interessting TEL 0051.

I would like to use UART for GPS and SoftwareSerial for GSM.

So, could you correct me and help me with this?
Here is how I thoung:

First
I put the S3 to GPS mode and not in the middle.

Second,
I want to use PD2 and PD3 of Arduino for SoftwareSerial.
I remove jumper J10 and J11. (I keep J12 as I am going to use PD5 to power the module.
And I have a double. Do I have to do somthink else? I think?
How can I make sure that PD2 and PD3 of Arduino is well connected to the circuit, and specialy to SIM908 pin?

Do you understand my whish?
What do you recommand me to do?

PS: To make the think easier, I also can use pin 10 and 11 for the Softwareserial (it does not matter, for me). But I will have the same question, how can I make sure the PD10 and PD11 of Arduino are well connect the SIM908 matching pins?


I get some information. Some informat state that pin 0 and 1 has not to be connect with Arduino and cruve it to pin 10 and 11. But as I whish to use UART for GPS, I think I would bette switch the S3 to GPS mode.

What are you suggestion, rate, and advise to complete my wishes?

Many thank for your help

Thank again for your reply. Let e resume again to make sure I understood weel.

If i want to use Serial(UART) and Softwareserial (SoftwareSeiral cell(10,11);
First I remove the pin0 and 1 as you show in your picture.

Because I left S3 in middle position and I trun the gsm mode
Code: Select all
digitalWrite(3,HIGHT);                                      //desable the GSM mode
digitalWrite(4,LOW);                                                  //Enable the GPS mode
I can read GPS data from Serial.read() (pin 0 and 1 of TEL0051)
and I can read GSM data from with cell.read(). (pin 10 and 11 of Arduino)By the way, I could send AT command for GSM function as ready/sending SMS, call etc?

Thank a lot for clarification.
For now I could test the module and I am happy. It seams to work fin even if I still have a lot to do......
