  3. The device's red and blue system LEDs will turn on at the same time.
    If the two LEDs do not turn on, disconnect the USB from the PC and repeat from step 2.

  4. Open the device manager on the PC and identify the COM port number that the device is connected to.

  5. Start TeraTerm and open the COM port.

  6. Set the serial port and terminal settings as shown below.

  7. The User Console mode will start up, and a prompt will appear when the enter key is pressed.
    If no prompt appears, disconnect the USB from the PC and repeat from step 2.

Challenge Registration

If connecting an STM32 Discovery device to the NEQTO service for the first time, it is necessary to perform the procedure to register a serial number for STM32 Discovery issued by the NEQTO Console to the device. This is called "challenge registration".

Due to challenge registration requiring a communication connection to the NEQTO Console, ensure that the communication settings are completed in advance.

The procedure is as follows:

  1. Complete the STM32 Discovery device registration and node registration on the NEQTO Console.

  2. View the details of the STM32 Discovery device registered in step 1. and note the challenge code.

  3. In User Console mode, enter the chal command. Specify the challenge code confirmed in step 2.

    CommandContentNote
    chal <Challenge Code>Schedules the challenge registration.
    Specify the 12 character challenge code.
    This command must be entered before entering the start command.

    User Console Mode!
    Enter challenge-code!

    > chal 123456789Abc↵
    OK

    > 


  4. Enter the start command to initiate the challenge registration.

    If the challenge registration is successful, the NEQTO service will continue to be launched.

    User Console Mode!
    Enter challenge-code!

    OK

    > start↵
    OK

    > Challenge failed. Check the network configuration and try again.

If the challenge registration is successful, it will not be necessary to perform the challenge registration from the next boot up.
If the device registration has been changed on the NEQTO Console, it will be necessary to re-perform the challenge registration.


Troubleshooting

The operating status of the device can be ascertained from the state of the system LEDs and the display of event messages.
