How To Configure DA16200MOD For WPA2 Enterprise

Hi James,

Thank you for posting your question online and your interest in our Wi-Fi products.
Please check our User Manual DA16200 DA16600 AT Command: UM-WI-003 DA16200 DA16600 AT Command User Manual (renesas.com)
You can find on 8.2 Wi-Fi Function Commands for WPA Enterprise, page: 61



You should also see on 8.2.1 WPA-Enterprise Connection Example, page:63

Hello,

Thanks for the information that you provided.  This is helpful.

However, our custom hardware is not designed to be able to use the UART0 or UART1 for use of the AT Commands.

UART1 on our board is user to connect to a USB to UART dongle that connects to our PC and serves as a command line interface and UART1 connects to a Display.

We need a way to configure the WiFi Function commands for WPA2 Enterprise without using the AT Commands.

Currently we use the setup command to configure the WiFi for plain old WPA security where we enter the SSID and the passphrase key.  Is there a method to implement this type of solution for WPA2 Enterprise?

We have to have WPA2 Enterprise for our product.

Is it possible to use UART0 with the AT commands?  If this is possible, can you provide information on how we implement this?

Thanks,

James

Hi James,

Thank you for the reply.
As you can see on the DA16200 Datasheet, 10.2 UART Registers, page: 96

If you want to use UART2 for the AT commands, you should go on config_generic_sdk.h file and define the appropriate macro:

///////////////////////////////////////////////////////////////////////
//
// SUB-features for Generic-SDK
//
///////////////////////////////////////////////////////////////////////

    #if defined ( __SUPPORT_ATCMD__ )

        //
        // Default interface of DA16200 EVK is UART1.
        // User can change host-interface kind to change as below four-types one.
        //
        #define __ATCMD_IF_UART1__                          // AT-CMD over UART1
        #undef  __ATCMD_IF_UART2__                          // AT-CMD over UART2
        #undef  __ATCMD_IF_SPI__                            // AT-CMD over SPI
        #undef  __ATCMD_IF_SDIO__                           // AT-CMD over SDIO

        #undef  __UART1_FLOW_CTRL_ON__                           // flow control of UART1

  /* Set to user costomer's configuration */
    ap_config_param->customer_cfg_flag = MODE_DISABLE;    // MODE_ENABLE, MODE_DISABLE

.Keep also in mind that on atcmd.c file you can find the implementation for the AT commands I shared on my previous answer.

Thanks for your reply.  Currently in order for us to configure a UART for use with AT Commands we would need to revise our hardware design, so use of a UART is not feasible at this time!!!!

Shown below is our current NVRAM environment variables for WPA2 setup.

[/DA16200] # nvram
Command-List is changed, "NVRAM"
[/DA16200/NVRAM] # getenv

Total length (318)
country_code (STR,03) ........ US
N0_Profile (STR,02) .......... 1
N0_ssid (STR,12) ............. "Jfethome2"
N0_psk (STR,13) .............. "Football95"
N0_key_mgmt (STR,08) ......... WPA-PSK
N0_proActKeyCaching (STR,02) . 0
SYSMODE (STR,02) ............. 0
MQTT_DUTY_CYCLE (STR,04) ..... 900
0:DNSSVR (STR,08) ............ 8.8.8.8
0:DNSSVR2 (STR,15) ........... 208.67.222.222
SNTP_RUN_FLAG (STR,02) ....... 1
AWS_PORT (STR,04) ............ 443
AWS_KEEPINTER (STR,05) ....... 1200
AWS_OTARC (STR,04) ........... 255
TZONE (STR,07) ............... -18000

For WPA2 Enterprise configuration, the following WiFi network environment variables as shown in the AT Command Manual are required to configured.

,,, [,] Create Enterprise profile to NVRAM. : Enterprise AP SSID. : Authentication mode for WAP-Enterprise. 8 (WPA-EAP), 9 (WPA2-EAP), 10 (WPA/WPA2-EAP). : Encryption Type. 0 (TKIP), 1 (AES), 2 (TKIP+AES). : Phase #1 EAP type. 0 (Mixed), 1 (PEAP0), 2 (PEAP1), 3 (FAST), 4 (TTLS), 5 (TLS) : Phase #2 EAP type. 0 (Mixed), 1 (MSCHAPV2), 2 (GTC) ,,, [,] Create Enterprise profile to NVRAM. : Enterprise AP SSID. : Authentication mode for WAP-Enterprise. 8 (WPA-EAP), 9 (WPA2-EAP), 10 (WPA/WPA2-EAP). : Encryption Type. 0 (TKIP), 1 (AES), 2 (TKIP+AES). : Phase #1 EAP type. 0 (Mixed), 1 (PEAP0), 2 (PEAP1), 3 (FAST), 4 (TTLS), 5 (TLS) : Phase #2 EAP type. 0 (Mixed), 1 (MSCHAPV2), 2 (GTC)

, Set User-ID / Password for WPA-Enterprise user account. : Login-ID for WPA-Enterprise user account : Login-Password for WPA-Enterprise user account

Would you please provide an example of what commands we should issue in order for these variables to be configured in NVRAM!!!

We are still not clear how we can configure and set these variables in NVRAM without having to use AT Commands!!!

Hi James,

Thank you for the reply.
Let me search internally if I am able to find any examples available for WPA2 Enterprise implementation inside our SDK and I will get back to you as soon as possible.

OV_Renesas,

Were you able to find any examples on how to configure WPA2 Enterprise?  Remember we don't have the ability to use AT Commands.  We are in need of getting WPA2 Enterprise working so we can start field trials of our product!!!

Hi James,

Apologies for the delay and thank you the reply.
I have raised an internal ticket regarding this and I will get back to you as soon as possible.

Hi James,

Apologies for the delay.
The WPA2 Enterprise is supported (without AT commands) only on our latest SDK v3.2.6.
You can download it from here:https://www.renesas.com/eu/en/document/sws/da16200-da16600-freertos-sdk-v3260?r=1600096
You can also find the AWS IoT Reference for SDK v3.2.6 here: https://www.renesas.com/eu/en/document/sws/aws-iot-reference-freertos-sdk?r=1600096
WPA2 is supported by default in this version.  You will not need to activate any feature.

Kind Regards,
OV_Renesas

Thanks for the update and for the information.  We understand!!!
