rickkas7, thanks so much for your prompt reply. I did try running the example code verbatim as a starting point. I have since adjusted the code to have the IP 8.8.8.8 which I believe is the IPv4 address of googles servers. I tried the example code listed above with the address changed to:
byte server[] = { 8, 8, 8, 8 }; // Google
This did not work. I wasn't sure if the cell modem was appropriately initialized so I tried to run the TCP example code on top of the tracker-edgeV15 software for the Tracker One:
#include "Particle.h"
#include "tracker_config.h"
#include "tracker.h"
#include <fcntl.h>
SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(SEMI_AUTOMATIC);
PRODUCT_ID(TRACKER_PRODUCT_ID);
PRODUCT_VERSION(TRACKER_PRODUCT_VERSION);
STARTUP(
Tracker::startup(););
SerialLogHandler logHandler(115200, LOG_LEVEL_TRACE, {
{"app.gps.nmea", LOG_LEVEL_INFO},
{"app.gps.ubx", LOG_LEVEL_INFO},
{"ncp.at", LOG_LEVEL_INFO},
{"net.ppp.client", LOG_LEVEL_INFO},
});
TCPClient client;
byte server[] = { 8, 8, 8, 8 }; // Google
void setupTCP()
{
Log.info("connecting...");
if (client.connect(server, 80))
{
Log.info("connected");
client.println("GET /search?q=unicorn HTTP/1.0");
client.println("Host: www.google.com");
client.println("Content-Length: 0");
client.println();
}
else
{
Log.info("connection failed");
}
}
void loopTCP()
{
if (client.available())
{
char c = client.read();
//Log.info(c);
}
if (!client.connected())
{
//Serial.println();
Log.info("disconnecting.");
client.stop();
for(;;);
}
}
void testFileOpen()
{
int fd = open("test.txt", O_RDWR | O_CREAT | O_TRUNC);
if (fd != -1)
{
Log.info("opened");
close(fd);
}
else
{
Log.info("not opened");
}
}
void setup()
{
waitFor(Serial.isConnected, 30000);
testFileOpen();
Tracker::instance().init();
}
void loop()
{
Tracker::instance().loop();
if(millis()>120000)
{
setupTCP();
loopTCP();
}
}
Here is the output log from this code (as much as my serial logger CoolTerm stores):

Do you have any suggestions for getting the TCP connection to work with the Tracker one? My overall goal is to perform an operation similar to that described by CanCon_ENG as described here: Best way to update local device with Particle - #3 by rickkas7
Thanks so much for your help and support!
