Demo using a Nimbelink Skywire cellular modem paired with ST Nucleo. This demo reads several sensors and reports them to a Freeboard dashboard using dweet.io from Buglabs
Dependencies: LIS3DH LM75B LPS331 hts221 mbed
Fork of Skywire_Demo by
Getting Started Guide
- Set the JP5 jumper to E5V on the Nucleo
- Place the Skywire Shield onto the Nucleo as pictured
- Place the Skywire modem onto the Shield as picture and attach the antenna U.FL coax cable as pictured
- Plug the 12V wall supply into the Skywire Shield
- Go to https://freeboard.io/ and create a user account
- Once you are logged into your Freeboard account, go to https://freeboard.io/board/PJI272 and clone the dashboard by clicking the CLONE link in the lower right corner
- Old Revision of dashboard is here https://freeboard.io/board/jqlneI
- Old Revision of dashboard is here https://freeboard.io/board/jqlneI
- The new dashboard will show up on you account list under My Freeboards, you can then edit the name to whatever you like
- Under the Datasources tab on the dashboard, click the skywire link
- Change the THING NAME field to a unique string, we recommended using the MEID or IMEI on the Skywire Modem, but it could be anything you want.
- Next, Import the Skywire_Demo program into the online compiler
- Open main.cpp. Starting at Line 58, there is a list of Skywire Modems. Uncomment the Skywire Modem that you are using. Make sure only one Skywire Modem is uncommented:
main.cpp
/* * 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
- Next, to Line 73 in main.cpp, and change the DeviceID to the THING NAME you entered into your Freeboard:
main.cpp
/* --CHANGE THIS FOR YOUR SETUP" -- */ #define DeviceID "DweetIODeviceName" //Freeboard DweetIO unique ID
- If applicable, go to Line 77 in main.cpp and change the APN to your specific APN:
main.cpp
/* --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 = "yourAPNhere"; #endif
- Compile and upload to the Nucleo, cycle power to the shield and the sensor data should start to upload to your new Freeboard.
