Hello,
I’ve followed the getting started guide to run FreeRTOS on ESP32_DevKitC. I’m able to build the Make files etc, but when I run $make flash monitor it hangs on starting WiFi.

It just sits here and never connects to my WAP.
So I know something is setup wrong, but need help to identify where.

Doing more testing I find that the SetupAWS.py script is throwing errors:

I’ve deleted the ‘Thing’, ‘Certificate’, and ‘Policy’ in my IOT Core account.
Tried cleanup and all other command switches with the setup script, but it always throws these errors.

Sorry to hear that the setup does not work for you. Would please check if WiFi SSID and Password are correctly configured in https://github.com/aws/amazon-freertos/blob/master/demos/common/include/aws_clientcredential.h#L58.

Thanks.

Nothing has populated in the aws_clientcredentials.h
I’m guessing that because SetupAWS.py setup is failing with these errors it’s not taking the parameters from configuation.json and populating this file?

I’ll try coding the wifi parameters in the credentials file and test.

Still will not connect, just hangs at “SYSTEM_EVENT_STA_START”
No client connection activity monitored on the WAP.

It seems that your configuration.json file has some invalid characters which is causing the setup script to fail. What is the content of configuration.json and how are you populating it?

Thanks.

i got the same Problem with the ESP-WROVER Kit which is also a recommended development board.
my configure.json:

“afr_source_dir”:"/home/torsten/amazon-freertos",
“thing_name”:“ESP”,
“wifi_ssid”:“WLAN-E33E75”,
“wifi_password”:“7856956690585151”,
“wifi_security”:“eWiFiSecurityWPA2”
}
the wifi test files from espressif worked for me, but the aws mqtt test project gives the same error as above.
I work with Linux 18.04.

about help i would be much appreciated.

Hello, would it be possible for you to attach your configuration JSON file here? Thank you.

Hi DanG-AWS

I have been having troubles setting up the file configure.json, I am not sure if I am establishing the right format of is something missing, I tried checking the trends already created in this Forum and I couldn’t find any solution out of the ones already created. How I am setting is like below:

{
“afr_source_dir”:"/home/yohan/Desktop/AmazonFreeRTOS-OTA",
“thing_name”:“thing”,
“wifi_ssid”:“",
“wifi_password”:"*”,
“wifi_security”:“eWiFiSecurityWPA2”
}

I realized that this wasn’t with the right format when in the flashing process, the process was freezing in the next command.

I (1234) WIFI: SYSTEM_EVENT_STA_START

Do you know what is the right format or if I am missing something? I have tried different configurations
Much appreciated your help

Hello YohanMetalform,

That behavior indicates invalid WiFi credentials. If you are trying to run a demo can you manually edit demos/include/aws_clientcredential.h If you are trying to run a test can you manually edit tests/include/aws_clientcredential.h. Double check that you the information you enter in the specified file matches the WiFi endpoint you are trying to get to. Can you attach the logs of running device, and when you try to configure the device with SetUp.py?
