Hi Lucas,
Thanks for your words. No, the protocol allows only step of 1, so you can’t do that.

Mmmm…
the Gcode output isn’t managed; the commands on documentation are wrapped from MKS WiFi firmware and do the work, not the printer board, and I don’t know as Marilin works.

For the “compilation” o web folder you can follow the instructions of the guide, but basically, after build the project you can launch the uploader of ArduinoIDE 1.x (now there is a version for 2.x, but I use the old one)

and you can find the file path in the console and grab It.

Basically in the temporary folder like C:\Users\renzo\AppData\Local\Temp\arduino_build_785244 you can find some file like so:

core
libraries
preproc
sketch
build.options.json
includes.cache
local.eagle.app.v6.common.ld
MKS_WIFI_upgrade_with_BeePrint_web_interface.ino.bin
MKS_WIFI_upgrade_with_BeePrint_web_interface.ino.elf
MKS_WIFI_upgrade_with_BeePrint_web_interface.ino.map
MKS_WIFI_upgrade_with_BeePrint_web_interface.spiffs.bin

For the Gcode follow the relative article with the specified code offered from the MKS_WIFI firmware

You can find the relative implementation here on the firmware.

Hi Victor,
I uploaded a new version with the Marilin command to the web UI.
To generate a bin, I followed the old guide and worked correctly.

I built your version, and you can download it from here.

Bye Renzo

[Renzo Mischianti]

Hi Fernando,
sorry for the late response.

I think the problem can be that From core 2 to core 3, TX2 and RX2 pins are changed

Try to force the pin number
LoRa_E32 e32ttl100(16, 17, &Serial2, 15, 21, 19, UART_BPS_RATE_9600); // RX AUX M0 M1

Hi,
sorry for the late response

The error (SSLClient)(SSL_ERROR)(m_print_br_error): Incoming protocol or record version is unsupported. indicates that the SSL/TLS version the server expects is not supported by your client. Check if your server enforces a specific SSL/TLS version (like TLS 1.2 or 1.3). Ensure that your ESP32 or SSLClient library supports the required version.
Try to modify the SSL settings on your server to allow older versions like TLS 1.1 or ensure the client can handle TLS 1.2+.
Bye Renzo

[Renzo Mischianti]

Hi,
I think that, as described in the error, the problem is that the version of SSL is not supported by SSLClient; try to check the server security settings.
Bye Renzo

[Renzo Mischianti]

Hi Edge,
to show the frequency as you need, you must put one of these define before the library include.

#define FREQUENCY_868
#include "LoRa_E32.h"

[Renzo Mischianti]

Hi Sachi,
try to post your code so we can try to help you.
Bye Renzo

[Renzo Mischianti]

Hi Adi,

I don’t think it’s possible for the E22 to communicate with the E32 directly. They use different chips and have different cryptographic systems, which makes them incompatible for direct communication.

Best,
Renzo

[Renzo Mischianti]

Hi Adam,
You are right. The C1 is correct. It is also in the library. I verified that but also checked the other set that must be respected; if you receive that message, you have something wrong or some noise with the device setting. But if it works for the other operation, we will never discover what it is :D.

Bye Renzo

[Renzo Mischianti]

Ahh! Yes, I already found that some models of E220 have this “issue,” but they’re working correctly.
Sometimes, there is a power supply problem. In your case, it’s more rare, but you can ignore that response.
Bye Renzo

[Renzo Mischianti]

Hi Adam,
If it’s well connected, there are two other options:

• the power supply is not sufficient;
• the device is broken.

Try to use an external power supply for the module.

Bye Renzo

[Renzo Mischianti]

Ahh! perfect!
I am waiting for your news.
Bye Renzo

[Renzo Mischianti]

Ahh, wait, you use uart directly to send messages.
If I remember, I applied encoding in the library to prevent problems with not-in-range characters.
Use the library.
Bye Renzo
