Customer Preparation for Sigfox Communication

Confirmation of device ID information
Before communicating with Sigfox, you need to activate the purchased evaluation kit on the Sigfox Buy website. Before doing so, please check the ID and PAC information of the evaluation kit.
For ⇒ details, please refer to “5.1.How to read ID and PAC”.

Evaluation kit activation
In order to communicate with Sigfox, It is necessary to purchase a line contract from Kyocera Communication Systems Co., Ltd. (hereinafter referred to as “KCCS”), the line operator of Sigfox’s Japan. For non-Japan correspondence, please contact the Sigfox operator in your country.

• details can be found in Section 5.2. How to register an evaluation kit.
• • If you rent an evaluation kit, you do not need to activate the evaluation kit.

Reading method of ID,PAC

ID and PAC information1 are required to register the device to Sigfox Portal2.

• The read ID and PAC are essential for Sigfox communication, so please back up the information so that you do not forget it.
  Follow the steps below to read the ID and PAC information.

[Procedure]

Use PowerSchell3 on a Windows PC and a PC.
First, PowerSchell requires advance preparation4.

1. In the Sigfox network, in order to confirm that the terminal has Sigfox communication authentication,
   Each device has a unique identification number, which is called DEVICE ID (abbreviation = ID) and Portable Authentication Code (abbreviation = PAC).

2. Sigfox Portal is a Sigfox site where you can register and manage Sigfox devices and check data delivered to the Sigfox cloud. (https://backend.sigfox.com/auth/login https://buy.sigfox.com)

3. PowerSchell is an extensible command line interface (CLI) shell and scripting language developed by Microsoft to replace the traditional DOS prompt, and is a scripting environment that has been standard since Windows 7.

4. PowerShell scripts are provided without PowerShell signing so that users can edit and use the execution policy. The initial value is set to Restricted, which prevents script execution. Therefore, in order to execute the script you provide, you need to edit the execution policy.

Preparing PowerSchell (How to Change the Execution Policy)

1. Right-click the Windows PowerShell icon in the Start menu and specify Run as administrator.

2. The PowerShell console screen will be displayed, so set the following.
   PS C:¥windows¥system32 >Set-ExecutionPolicy RemoteSigned
   This allows locally stored scripts to run. Also, non-local scripts (downloaded from the Internet) can only be executed if they are signed.

3. Connect the evaluation kit to the Windows PC via USB.

4. In order to use the command script, from the support site described in Introduction (page 2), LWCSP for ML7456N SB Please download it to the connected PC and place it in an appropriate place.

5. On PowerSchell, navigate to the folder where the command script is located.
   PS C:¥windows¥system32>cd C:¥¥¥ ML7456_LWCSP_for_U16_VXXX¥script¥command
   (Please match the *** part and folder hierarchy to the location of the file you downloaded.) )

6. In PowerShell, run the command script “sigfox_get_id_pac.ps1”.
   「. PS1″ extension is a PowerShell script file. In PowerShell, the execution instructions for a script file must explicitly specify the path. Therefore, script execution in PowerShell is executed with an absolute path or with a .¥ at the beginning of a file in the current directory.
   Script execution example：PS C:¥Users¥XXX¥XXX¥XXX¥script¥command>.¥ sigfox_get_id_pac.ps1 COM(“” specifies the COM number to which the evaluation kit is connected.) )

How to register the evaluation kit

• In order to transmit data from the Sigfox device to the Sigfox cloud, a line contract with KCCS is required when using it in Japan country.

• Please refer to “Register device as a development kit (DevKit)” on KCCS’s technical blog site below and complete the device registration procedure.
  https://qiita.com/organizations/sigfox

• In addition, if you want to apply for a line contract other than the above, it is posted on the following site of KCCS, so please apply and register as appropriate according to the posted contents.
  https://www.kccs-iot.jp/buy/flow/

• Reference: Approximate line charge per line ¥700~¥1,200 Device/year (as of January 2020) Charges vary depending on the number of communications per day and the presence or absence of Sigfox Atlas (location services).

Sigfox Communication

This chapter describes the operations for transmitting to a Sigfox base station. In advance, see “5. configure the contents described in “Advance preparation for Sigfox communication”.

Data Transmission Method to Sigfox cloud

In PowerShell, run the command script “sigfox_xxxx_send_frame_msc.ps1”. Script execution example：PS C:¥Users¥XXX¥XXX¥XXX¥script¥command>.¥ sigfox_xxxx_send_frame_msc.ps1 -rc_mode SFX_RC3C -com_name COM(“” specifies the COM number to which the evaluation kit is connected.) )

Example execution response

Confirmation Method of Sigfox cloud

S Device management and data confirmation that is registered to Sigfox service is done on the Sigfox Portal (https://backend.sigfox.com/auth/login)*6 . Please complete device registration that is introduced at the previous page, transmit data, then confirm the data on it.

Sigfox ID is necessary to login the Sigfox Portal. It can be produced in the procedure of KCCS line contract.

Switching Operation Modes

In this chapter, 1) Sigfox communication, 2) IEEE802.15.4g peer communication, and 3) Sigfox periodic transmission. Describes how to switch between sample application types. Each of these modes of operation allows the following sample applications to be configured as startup software:

1. Sigfox communication Sigfox bypass application
2. IEEE802.15.4g Coupled Radio Bypass Application
3. Sigfox Periodic Transmission Sigfoxte Periodic Transmission Application

These sample applications can be modified from PowerShell with syscmd_set_start_app_number.ps1 scripts. After setting the desired startup software in PowerShell, resetting will launch the specified sample application.

• The factory default of this evaluation kit is set to operate the Sigfox bypass application.

How to switch between sample applications

1. Launch PowerShell.
2. On PowerSchell, navigate to the folder where the command script is located (¥¥¥script¥command).
3. In PowerShell, run the command script “syscmd_set_start_app_number.ps1”.

• Sigfox bypass applications：.¥syscmd_set_start_app_number.ps1 -app_number 0 -com_name comXX
• Radio bypass applications：.¥syscmd_set_start_app_number.ps1 -app_number 1 -com_name comXX
• Sigfox periodic transmission applications：.¥syscmd_set_start_app_number.ps1 -app_number 2 -com_name comXX

Execution example

How to review the sample application

You can check if the desired sample application is set up by using the syscmd_get_start_app_number.ps1 script from PowerShell.
.¥syscmd_get_start_app_number.ps1 -com_name comXX
