Hi Supachokhansaran,
you must clean your code by disabling the single features and checking who created the problem.

If you want more information about stack trace, and check It detal.

or you can use Arduino IDE plugin.

Hi Sid,
sorry, your message went to spam so that I will answer only now.
You are right, I push a fixed version without json requirements.
Thanks, Renzo

Hi Srill,
in which line?
Bye Renzo

[Renzo Mischianti]

Hi Srill,
perfect!
Bye Renzo

[Renzo Mischianti]

Thanks for your feedback, JaTo; I often find some bugs in EByte software, and I try to fix Them when I find them.

Hi Srill,
Strangely, the library does not say again any response from the device. You get
Available buffer: 0 structure size: 6
and means that the device doesn’t give a response.

There is a power supply problem or wiring problem.

Hi Andrecolz,
probably some internal management, try to remove/change all pull-up resistors and try to use other pins.
Bye Renzo

[Renzo Mischianti]

Yes, thanks, I’m going to test It too.
Bye Renzo

Hi,
It seems that the pinout Is wrong; put the device on a breadboard and, with an LED, test the single pin output.
Give me feedback RM

[Renzo Mischianti]

No no,
I need the first part of Serial output where the pin initialized are printed.
Bye RM

[Renzo Mischianti]

Please add also the pin initialization part.

Hi Elkez,
I usually use this solution
Emergency power bank homemade

The step-up drain current is from 18650 (you can put more than one in parallel), and the output is 600mha, which I think is sufficient to power the 400T33D, but check with the tester how much the current drains the device.

Hi,
use get configuration sketch and enable the debug.
After that post the output.
Bye Renzo

[Renzo Mischianti]

Hi,
I think It’s Serial1 not Serial2.
And there isn’t necessary specify the pin of the serial.

Hi Erick,
Do you already try to set the SD filesystem in the external storage?
