ERROR sending mesg to ESP

i recently got the new SmartCitizen 2.1 Urban Sensor Board and Data Board. At first i got no problem connecting to the wifi and sending data to the plataform. But after a weekend off, the citizen stopped publishing, i went to the serial monitor and there i found the problem, the board can’t communicate to the ESP, here’s the output:

Hello Alison,

Sorry to hear that your kit is having problems.
Do you changed something in the kit or in your Wi-Fi on the weekend off you mention?

To try to diagnose your problem can you please click the reset button and describe me the behavior of the Wi-Fi led when the kit is trying to connect?

Another thing to try is enabling the debug messages during the communication with the ESP, you can do that with the command:

debug -espcom

You will see a lot more info in the console, maybe we can find a clue of what’s happening!

Keep us posted!

Thanks for the reply, no changes were made in either the SCK or the WiFI over the weekend.

The SCK connects fine with the wifi, i can see it in the wifi administrator page. But for some reason it has problems in the handshake phase when configuring the SCK(the wifi LED blinks from time to time in sync with the status LED).

The output for debug -espcom is:

Hi @alison.santos,

  1. Did you replaced the SSID and PASSWORD of your Wi-Fi for security or it looked actually as you post it?

{“cs”:1,“ss”:“SSID”,“pa”:PASSWORD,“ts”:1,“to”:“jpfzxh”,“ver”:“0.9.6-53fba6b”,“bd”:“2019-08-27T16:58:01Z”,“ac”:6}

  1. Could you register the sensor as on SD Card mode and then share us the url of the device in the platform when you finish?

Thanks you!

  1. the SSID and the PASSWORD are right, i changed it before posting in the forum for security reasons.

  2. https://smartcitizen.me/kits/10536 here is the URL, i uploaded some data it recorded also

I just added your device key (token) to the device you registered on SD card mode.

That means if you press the button on your Kit till the led turns BLUE, your device should start publishing data to the platform via Wi-Fi, too.

Let me know if this works! It will help us know a little bit better what is going on

It worked! Thank you so much for the support.

Great it works!

Let us know if you have any more problems!
