AT Commands Siemens C60 - GSM-Forum

rlucian90 · 03-19-2013, 23:01

Hello guys.

For some months i'm trying to make the phone to reply on AT commands but without success.
Firstly i was trying with Nokia 1100 and 1600 but i noticed that those are on FBUS and i want the AT commands, a cheap solution also.
So i'm having now a Siemens C60. I made a cable and connected it to the computer. When i transmit AT command i got no reply.
Please can you tell me what i'm doing wrong?
Does the Siemens C60 also need the CTS RTS and DCD connection ?

Now i'm using this:

Hi,

Yes i am .

Thank you so much for the diagram. I will try it and hope it works . Can't i use it with continous DC Voltage from a power supply not from serial port pin4 ?

I tried it but without any luck. I will try it again and double check it before hope will be ok.

What voltage should be on TX or RX , 2.7-2.9V ?

Thank you.

Hi there,

I can't use that test point on the C60 cause it isnt mine.

That isn't the same test point for the A57 ? If i do this test point and wire the TX RX and GND only on MAX232 and then in PC serial port can i use Freia to unlock phone and then to use AT commands ?

Thank you.
