I am trying to compile the reed example with minimal secure coap code but in the process i am getting following error for mbedtls

Hi,

Hope you are doing well. Could you please describe the procedure you followed?

Can you clarify what do you mean with "reed example with minimal secure coap code"?

Best Regards,

Ricardo

Hello @Ricardo_Zamora

I am developing an apps based on k32w061dk6_reed_ble_wuart_bm example where i need to add the secure coap support. I added following lines in <Proj Dir>/MCUXpresso_11.4.1_6260/workspace/k32w061dk6_reed_ble_wuart_bm/source/reed_app.c

otCoapSecureSetSslAuthMode(gpOpenThreadInstance, false);
otCoapSecureSetClientConnectedCallback(gpOpenThreadInstance, HandleConnected, NULL);

otCoapSecureSetDefaultHandler(gpOpenThreadInstance, DefaultHandler, NULL);

otCoapSecureStart(gpOpenThreadInstance, OT_DEFAULT_COAP_SECURE_PORT);

I tried defining OPENTHREAD_CONFIG_COAP_SECURE_API_ENABLE as 1 in <Proj Dir>/MCUXpresso_11.4.1_6260/workspace/k32w061dk6_reed_ble_wuart_bm/source/config.h

and when I tried to build I am getting following errors

undefined reference to `otCoapSecureSetClientConnectedCallback'

undefined reference to `otCoapSecureSetDefaultHandler'

undefined reference to `otCoapSecureStart'

Please guide the steps to enable the secure coap support in K32W SDK 2_6_4.

Thanks!!

Also one more question what are the steps to make changes in openthread libraries available with the SDK
