TwilioTSexample191121-output.txt

I am using the example (to send an SMS from an Arduino) at https://www.instructables.com/id/Send-SMS-from-Arduino-over-the-Internet-using-ENC2/

I have triple checked the Twilio credentials entered into the ThingHTTP project and the ThingHTTP project's API key.

The Arduino code and the serial output text are below...

/*
Send SMS from Arduino over the Internet using ENC28J60 and Thingspeak
Change one line to use with ethernet shield
Add sensor readings in the loop and a time interval
Using Arduino UIP library from https://github.com/ntruchsess/arduino_uip
Code based on Sparkfun's data logging service data.sparkfun.com
URL encode function from http://hardwarefun.com/tutorials/url-encoding-in-arduino

#include <SPI.h>
//change the following line to #include <Ethernet.h> to use the eithent shield
#include <Ethernet.h> 
// Enter a MAC address for your controller below.
byte mac[] = { 0x00, 0x24, 0xd6, 0x7f, 0xa2, 0x54 };
//thingspeak server
char server[] = "api.thingspeak.com";
//if DHCP fails, use a static IP
IPAddress ip(192,168,0,199);
// Initialize the Ethernet client library
EthernetClient client;
//API key for the Thingspeak ThingHTTP already configured
const String apiKey = "<<my API code fromn ThingHTTP project>>";  
//the number the message should be sent to
const String sendNumber = "<<my cell phone number>>";    // format "+1nnnnnnnnnn"
void setup()
{
  Serial.begin(9600);
  //set up Ethernet:
  setupEthernet();
  
  //send the sms
  Serial.println("Sending SMS");
  
  //this function will send the sms
  //the first argument is the number to send to, formatted like this +12345678901
  //the second argument is the body of the text message, which must be within URLEncode()
  sendSMS(sendNumber, URLEncode("Hello World!"));

Would appreciate some help on this. Any suggestions/theories???

Got it. Pilot error... Twilio account id and auth code had a space at the end that should not have been there. Didn't realize double clicking a number selected the number with a space at the end.
