@/sim900-gprs-sendsms

Node allows to send an SMS messages using GPRS shield based on sim900 chip.

UARTnumber

Hardware serial port number.

BAUDnumber

Data rate in bits per second (baud) for serial data transmission.

TELstring

Mobile telephone number in a format used in your country.

MSGstring

SMS text message. The limit is 128 characters.

SENDpulse

Triggers a new SMS sending.

RSTpulse

Triggers UART initialization.

ERRpulse

Fires if sending failed.

DONEpulse

Fires on sending complete.

To use the node in your project you should have the gabbapeople/on-board-computer library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
