hi, I'm Gabriel
I have at home a modem GSM Siemens MC35 and I olso try to send SMS with Serial Protocol function from an Easy 800 .
I did' t succeded yet ,and I want to tell you what I now may be we will find toghether a way to make this work.
I am comunicating and sending SMS with the moden from the Pc .
To initiate a send job to modem the sintax will Be:
AT+CMGS="Phone nunmber"OD
[OD is Carriage return in Hexa]
Then I have to start a new send task :
My messange 1A
[1A is Substitute]
Both CR [OD] and SUB [1A] are very important to be placed at the end , I supose in Easy it must be writen in end sequence.
I do not think the example from Moeller using SP function block will work , my opinion is that you must use to SP function ,first one to tel the modem what you want him to execute and the next one with mesege and end of task.
