Re: Vending Machines sending SMS at inventory low condition.





I have search this forum under “SMS” and have not found how to send (I’m interested in sending only) SMS messages using a Cellular Modem that accepts AT commands like this one;

I have a customer who has over 350 Coke, Snack and Candy Vending Machines, with the cost of Gasoline reaching 65 cents per liter in my country; it becomes absurd to visit one of these machines just to find out that there was not need in the first place.



I suggested installing the shown above (link) $100 cellular modem at each of these machines and connecting it to the spare RS232 port found in the pc motherboard inside the Vending Machine.



We already find out that our local cellular network will provide us with a SIM card equipped cell phone line (for data only) for just $10 a month per machine.



Every time a specific product runs low or the coin changer is empty the machine itself will dial 3 cellular phones and send an SMS message like this.

@ / 2323 / #1-3 / #2-7 /#3-12 /#4-0 /#5-3 /#6-8 /#7-1 / $14 / $116 / @
​

(Meaning: Machine Code / Lane # follows by the quantity left follow by amount left in the changer, follow by amount left in the bill acceptor) \



I’m using VB 2005 and noticed that it has a SerialPort class.



Question:

Has anyone written the correct code using this or any other class to send SMS messages using AT commands? If anyone is interested I have a couple of modems spare.



Please let me know I will appreciate it.



Thanks all
