Hello,

I try to communicate with a Siemens TC35i gsm module, but with no luck.
I can send sms, but when i want a response for a command, it will not work.

For example, when i use this program to display the model identification, i get the AT command string back in the debug (AT+CGMI), what is wrong?

answer VAR Word

SEROUT 0,16780,["AT+CGMI", 13]
SERIN 1,16780,[STR answer\9]
DEBUG STR answer
DEBUG "Klart!"

Best regards:

Mikael

    Links to the items you are asking questions about are always helpful. Also how you have everything connected.

    Here is a link to the manual: http://www.rfsolutions.co.uk/acatalog/tc35i_atc_v0301.pdf
    The module is directly via two resistors to the bs2:s i/o pins.

    Do you know the module works? Have you ever gotten it to send responses back with any device like your computer? Very little in the manual talks about how to connect it to another device. Do you have that info?

    When i send a sms, i have a line that wait for a "OK" answer, and that works fine.
