Figure 38. EVSE connection fails
In this case, check that your Ethernet cable has internet connection. Verify that you used the correct settings and definitions
in the "EVSE_config.h" file, matching the ones in the device connection prompt in your Azure IoT Central application. If you
still cannot find the cause of the error, power cycle or reset the board and try to connect again.
6. This step is optional, but recommended. When you have verified that the connection is successful, DPS is no
longer required. The DPS process must only run once to obtain the host-name-connection string. Upon a successful
completion of DPS and for the future connection, it is recommended to move to a direct connection to the Azure
IoT Central host, which reduces the connection time. Therefore, the "EVSE_DPS" define can be set to 0 and the
"HOST_NAME" macro can be defined with the host-connection string. The host name is printed to the device's serial
terminal during boot, as shown in
.
When setting "EVSE_DPS" to 0, specify the host name or connection string. You can copy them from the serial terminal.
Figure 39. Specifying host name
Proceed to flash the new settings of the host controller and verify that you have a successful connection with your Azure
IoT Central application.
