Other Parts Discussed in Thread: CC3120MOD
Hi Team,
Customer is using MSP432E401Y in UPS communication card, but have some issue when run the Azure mqtt client example code. Could you give some comments? Thanks.
1. Customer is using Azure mqtt client example code, what they modified is only the ntp server ( change from NULL to their own ntp server ), but the example can't get ntp time. The CCS console output is as below.

Notes that they checked the ntp server works well with their old network card, and also checked it works OK with following command line.
2. Based on Azure mqtt client example, they modified the code from ethernet connection to wifi connection (MSP432E401 + CC3120mod plugin in AP mode).
They find there is no issue with ntp server connection, and they saw good messages “IoTHubClient_LL_SendEventAsync accepted message [x] for transmission to IoT Hub.” But after about 3 minutes, ndk report server alert “Service Status: DHCPC : Enabled : Fault : 002”. And they do not see good values from their Azure cloud.
