NimbeLink / Mbed 2 deprecated Skywire_Kinetis_K64_demo

Release 1.0 supporting the Kinetis Freedom K64F board and NimbeLink NL-AB-ST-NCL and NimbeLink NL-SWSK. Tested with NL-SW-1xRTT-V and NL-SW-EVDO-V modems.

Dependencies:   LIS3DH LM75B LPS331 mbed hts221

Getting Started Guide

Note for the NL-AB-ST-NCL: In order to use the NimbeLink NL-AB-ST-NCL with the NXP FRDM-K64F, you must populate Resistors R2 and R8 while removing resistors R1 and R7. The NimbeLink NL-AB-ST-NCL will not work with the FRDM-K64F unless this change is made.

Note for the NL-SWSK: In order to use the NimbeLink NL-SWSK with the NXP FRDM-K64F, you must move Jumpers J3 and J4 to pins 2 and 3. The NimbeLink NL-SWSK will not work with the FRDM-K64F unless this change is made.

  • Place the Skywire Shield onto the FRDM-K64F as pictured
  • Place the Skywire modem onto the Shield as picture and attach the antenna U.FL coax cable as pictured
  • Screw in the antenna
  • Plug the 12V wall supply into the Skywire Shield
  • For serial debugging, plug a micro-USB cable into port J26 of the FRDM-K64F. If you are using Windows, make sure you have the serial drivers installed-please consult the guide at https://developer.mbed.org/handbook/Windows-serial-configuration for installation.Use a terminal emulation program such as TeraTerm with the following settings:
    • Baud Rate: 115200
    • Data: 8 bit
    • Parity: none
    • Stop: 1 bit
    • Flow Control: none /media/uploads/kylerodgers/fdrm-k64f.jpg
  • The new dashboard will show up on you account list under My Freeboards, you can then edit the name to whatever you like /media/uploads/kholland/default_skywire2.jpg
  • Under the Datasources tab on the dashboard, click the skywire link /media/uploads/kholland/default_skywire5.jpg
  • Change the THING NAME field to the MEID of the Skywire Modem. The MEID is printed on top of the modem. Otherwise, you can get the MEID from the serial output. /media/uploads/kholland/default_skywire4.jpg
  • Next Import the Skywire_Kinetis_K64_demo program into the online compiler
  • Compile and upload to the FRDM-K64F, cycle power to the shield and the sensor data should start to upload to your new Freeboard.
