u-blox / Mbed OS C027_SupportTest

C027_Support library test

Dependencies:   C027_Support

Dependents:   C027_SupportTest_xively_location software_test_v1

Fork of Seeed_GPRS_Library_HelloWorld by wei zou

When running this example make sure you have:

  • edited the SIM PIN, APN, USER and PASSWORD for you network operator
  • have inserted a SIM card with enough credits
  • the antennas connected
  • have good reception (especially for GPS)
  • installed the mbed CDC drivers if you run windows
  • connected a terminal program, such as teraterm

The example will connect the modem to the network and attach it. I will place a post request to download a file from mbed website. It will do a USSD request and finally wait for incoming SMS. It will try to answer your SMS (try asking "where are you").

You should see a similar output in your preferred console program:
