Description

I try to use the CC1310F Launchpad by TI to communicate with the Sigfox infrastructure.

CC1310LaunchPad

Connecting with SmartRF

On Windows, run the SmartRF program. You should see two connected devices (one CC1310 LaunchPad has two interfaces).

Select the XDS110 Class Application/User UART. At first, the device is “Unknown”. You have to select the target device. I have a CC1310F128.

Right clic and “connect”. By default, the bootloader mode was not enabled so I got the following message:

To enable the bootloader mode, hold the “SELECT” button (BTN-1, on the left) and press the “RESET” button (on the top). Then try to connect again and you should see the following:

You can now get board information such as the MAC address (we will need it soon).

Getting CCS project from Sigfox

The only way I found was to send an email to tech-pi-team@sigfox.com and ask for it. They replied with 3 hours.

Getting the Sigfox_data.h from TI

Send an email to sigfox@list.ti.com with the MAC address, your name and the company you work for. They should reply with one sigfox_data.h per device.

Compile CCS project (GNU/Linux)

dowload and install CCS from official TI Wiki (I used 7.0.0)
dowload and install TI-RTOS here
- I first had the following error with TI-RTOS version 2.21: Description Resource Path Location Type: identifier UARTCC26XX_HWAttrsV1 is undefined CC1310DK_7XD.c /TI_SIGFOX_CC13xx_v0.13 line 133 C/C++ Problem I then installed a previous version (2.18) following this post. It did not work. I restarted CSS. It worked.
I then found that I had to change UARTCC26XX_HWAttrsV1 to UARTCC26XX_HWAttrsV2 for it to work with the TI-RTOS version 2.21.

Flash the project onto the board

select the green bug to run the debugger (that will flash the board)
if you don't put the board in bootloading mode (as described in the first section), you will get errors:

Connect to the terminal (I use minicom) with the following parameters: 115200 8N1 I got a nice: Initialization error This is because I have to replace the file sigfox_data.h by the one that TI gave me.

replace the file apps/sigfox_data.h with the one provided by the TI support
select the green bug to run the debugger. It should be successful this time

Getting the Device ID and PAC number

Once the board is flashed, you can connect throught the terminal (minicom). No message should be displayed. To see what you are typing, enable “local echo”.

Write the following and press enter: `AT$ID?`` A wild 8 digits device ID appears !
Write the following and press enter: `AT$PAC?`` You should get a 16 digits PAC number.

Activate your device

Activate you device using your device ID and PAC number on: https://backend.sigfox.com/ If it does not work, send an email to Sigfox again. I got a reply within a day. My device was activated after 3 days.

Send message

I had to change the MODE on the sigfox_demo.h file because I’m in Europe: //#define MODE_ARIB #define MODE_ETSI

Sigfox Backend Callbacks

On the sigfox backend, you can create callbacks to trigger some remote function or forward data. Here is what I’ve done:

I am sending the data in Json to a node-red instance on IBM Bluemix.
