This library is intended to be used with u-blox products such as the C027 or a shield with u-blox cellular and GPS modules like the cellular and positioning shield from Embedded Artist.

For 2G/GSM and 3G/UMTS you need to:

  • have a SIM card and know its PIN number
  • need to know you network operators APN setting These setting should be passed to the connect or init and join functions. You can also extend the APN database in MDMAPN.h.

For CDMA products you need to make sure that you have provisioned and activated the modem with either Sprint or Verizon.

mazgch 85:dd8f4f0d0ca9 4 APN stands for Access Point Name, a setting on your modem or phone
mazgch 85:dd8f4f0d0ca9 5 that identifies an external network your phone can access for data
mazgch 85:dd8f4f0d0ca9 6 (e.g., 3G or 4G Internet service on your phone).
mazgch 85:dd8f4f0d0ca9 7
mazgch 85:dd8f4f0d0ca9 8 The APN settings can be forced when calling the join function.
mazgch 85:dd8f4f0d0ca9 9 Below is a list of known APNs that us used if no apn config
mazgch 85:dd8f4f0d0ca9 10 is forced. This list could be extended by other settings.
