Detailed description

No detailed description exists yet for this component

Examples

Example program that checks for network connection and then allows a number to be texted or voice dialled.

Waits for connection to be established before allowing texts or calls to be made.

The number at the top of the file in the calculation icon needs to be edited to a number to connect to for texts and calls.


Arduino Connections:

D8-D13 - LEDs / D8 = Connection Status - Flashing = Connecting / D9 Text sending / D10 Call Active

D0-D7 - GSM

A0-A5 - Switches - A0 = Send Text / A1 = Start voice call / A2 = End call

Arduino GSM Example


PIC Connections

B0-B7 - LEDs / B0 = Connection Status - Flashing = Connecting / B1 Text sending / B2 Call Active

C0-C7 - GSM

A0-A7 - Switches - A0 = Send Text / A1 = Start voice call / A2 = End call

Property reference

Properties
Expect Echo
Sets if we expect an echo of any data we send out to the GSM modem. Most AT type modems (e.g. GSM modules) will automatically echo back incoming data. 
String Array Size
Amount of RAM memory to dedicate to receiving responces from the GSM 
Message Array Size
Amount of RAM memory to dedicate to storing the last SMS message received by the GSM. 
Script Count
Maximum number of scripts to store in the device's ROM 
Script1
ASCII based AT command data stored in ROM and used when sending script 1 
Connections
Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. 
TX
Pin to be used for Transmit data 
RX
Pin to be used for Receive data 
Use Flow Control
Flow Control (Handshake) enable or disable. On: Two I/O pins are used to control the flow of data in and out of the device. Off: Flow control is disabled. 
Baud Options
Baud rate option selector 
Baud Rate
 
Simulation
Label
Textual label shown on the component I/O flasher 
Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. 
Console Data
Selects if the console data is automatically generated or not 
Console Columns
Number of characters that can be displayed on a single line of the console. 
Data Source
Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port API - Routes the communication data via a data API component on the Panel.
