That information can be * viewed using a Freeboard at www.freeboard.io (account required). Depending on your * ST Development Kit version, clone the following freeboard: * Rev A (Legacy): https://freeboard.io/board/jqlneI * Rev B (Current): https://freeboard.io/board/LhnbrX * * Please consult the wiki for more information */ /* * INSTRUCTIONS FOR USING THIS CODE * 1. Under the "DEFINE THE SKYWIRE MODEM" section of the code, uncomment the modem that you * are using to enable to proper setup and features of your Skywire modem. * * NOTE: Make sure the other Skywire modems listed are commented out. * * 2. Change the "DeviceID" to a unique identifier for your Nucleo board. One recommendation * would be to use the MEID/IMEI of your Skywire Modem. * * 3. If applicable, change the APN for your Skywire Modem. */ #include "mbed.h" #include "LPS331.h" #include "LIS3DH.h" #include "LM75B.h" #include "hts221.h" #include <string> /* * DEFINE THE SKYWIRE MODEM * Uncomment only the modem that you are using. * Make sure only one modem is uncommented! */ //#define NL_SW_1xRTT_V // Verizon 2G Modem - CE910-DUAL //#define NL_SW_1xRTT_S // Sprint 2G Modem - CE910-DUAL //#define NL_SW_1xRTT_A // Aeris 2G Modem - CE910-DUAL //#define NL_SW_GPRS // AT&T/T-Mobile 2G Modem //#define NL_SW_EVDO_V // Verizon 3G Modem //#define NL_SW_EVDO_A // Aeris 3G Modem //#define NL_SW_HSPAP // AT&T/T-Mobile 3G Modem //#define NL_SW_HSPAPG // AT&T/T-Mobile 3G Modem w/ GPS //#define NL_SW_HSPAPE // GSM 3G Modem, EU #define NL_SW_LTE_TSVG // Verizon 4G LTE Modem //#define NL_SW_LTE_TNAG // AT&T/T-Mobile 4G LTE Modem //#define NL_SW_LTE_TEUG // GSM 4G LTE Modem, EU //#define NL_SW_LTE_GELS3 // VZW LTE Cat 1 Modem /* --CHANGE THIS FOR YOUR SETUP-- */ #define DeviceID "SkyWire02" //Freeboard DweetIO unique ID /* --CHANGE THIS FOR YORU SETUP (IF APPLICABLE)-- */ #if defined NL_SW_HSPAP || defined NL_SW_HSPAPG || defined NL_SW_HSPAPE || defined NL_SW_LTE_TSVG || defined NL_SW_LTE_TNAG || defined NL_SW_LTE_TEUG || defined NL_SW_LTE_GELS3 std::string APN = "3,"IPV4V6","NIMBLINK.GW12.VZWENTP"";
