This is a UBLOX Sara R410M Shield from Sparkfun.com
I gave up on TCP connections to Hologram…
I did get HTTP to send data to www.thingspeak.com for my weather monitor.
I get a positive response from thingspeak and can verify that by looking at the Sara R4 file system and a file I named GetFile captures the response:
AT+URDFILE="GetFile"

OK
The HTTPC command, however, times out and returns negative status after the 180s default time out.
