Somachine basic SMS function

1 post in this topic

Hi folks,

I'm using TM200CE40R comm with SMS modem  GT-7600E via TMCR2SL1 RS232. I was using send_receive_msg to send the SMS functions. The SMS has been sent out successfully. 

I can get "OK" response at hyperterminal. However, I'm facing a problem to get the modem response "OK" at PLC. I always receive the same commands that I had sent out. Then, I turn off the echo mode by using AT command ATE0. Suppose I should get "OK". In the end, I get 16#0D0D (carriage return). 

Anyone have better idea to counter this or any experience to have better setup? Do I have to use SR2MOD03 with send_receive_sms function?
