Da16200 connecting to AWS

Hi There,

Thanks for your question. Can you please share the complete log file? What is the SDK version that you are using? 

If you are using the AT Commands, please also share the sequence of the commands.

Thanks, PM_Dialog

Hi There,

Thanks for sharing the complete log file. We'll go through it. In the meantime, can you check if you can replicate it with our latest SDK release?

Thanks, PM_Dialog

I created an AWS thing (neuroalert) and downloaded the certificates. my settings are shown below

MQTT Client Information:
  - MQTT Status  : Not Running
  - Broker IP          : ****-ats.iot.us-east-1.amazonaws.com
  - Port               : 8883
  - Pub. Topic         : da16k
  - Sub. Topic         : da16ks
  - QoS Level          : 1
  - TLS                : Enable
  - Ping Period        : 600
  - TLS Incoming buf   : 4096(bytes)
  - TLS Outgoing buf   : 4096(bytes)
  - TLS Auth mode      : 1
  - User name          : (None)
  - Password           : (None)
  - Client ID          : neuroalert
  - MQTT VER           : 3.1
 

I get the following

I tried using the same certificates to send a message using mosquitto_sub.exe on my PC. the 3 certificates are the same as cert 0/1/2 and the broker and topic are the same. It works perfectly from my PC using the certs, broker, and port as shown below. these match the ones in the DA16200 board. The DA16200 does not work. What am I missing?

PS C:\Mosquitto> .\mosquitto_pub.exe -h *****-ats.iot.us-east-1.amazonaws.com -p 8883 -t da16ks -m "hello world" --cafile .\AmazonRootCA1.pem --cert .\neuroalert-certificate.pem.crt --key .\neuroalert-private.pem.key -d

Client (null) sending CONNECT

Client (null) received CONNACK (0)

Client (null) sending PUBLISH (d0, q0, r0, m1, 'da16ks', ... (11 bytes))

Client (null) sending DISCONNECT

PS

in AWS IOTR at topic da16ks

hello world

Hi There, 

Can you please indicate the SDK example that you are using? is it the SDK image, or the Eclipse project?

Additionally, are you using AT commands? Can you please share the steps we should follow in order to replicate it?

Thanks, PM_Dialog

I am using the example below and just setting the MQTT parameters under the [/DA16200/NET] # tab.

I am not using any AT commands. I am using the CERT command to load the same 3 cert files that I have used on my local PC to connect to AWS as shown above. I am using teh same AWS endpoint and port. the only difference is the DA16200 eval board. I am building and compiling with Eclipse. I am flashing with TeraTerm using the macro option in directory shown below.

C:\.....\SDK\DA16200_SDK_FreeRTOS_v3.1.2.0\DA16200_SDK_QFN_v3.1.2.0\customer\projects

C:\.....\SDK\DA16200_SDK_FreeRTOS_v3.1.2.0\DA16200_SDK_QFN_v3.1.2.0\img

any idea why I cannot connect to AWS? This is a requirement of the project.  I have loaded the certs and failed to connect to my AWS account. I have used these same certs from my local PC and made a connection and could publish to my AWS account as shown above. This indicates teh host name and certs are correct. Can someone point me to anyone who can use the DA16200 and connect to AWS using TLS.

Hi tjm, 

I have escalated this to our CS Team internally to take a look. I'll get back to you ASAP. 

Thanks, PM_Dialog

Thank you very much. I am sure it is operator error and I have just missed a setting or something. I followed the instructions in the MQTT document below to get it work without TLS on my local MQTT broker but could not get it to work with TLS either on my local broker or AWS.
