Hi,
for the interrupt you can use this constructor:

	PCF8574(uint8_t address, int sda, int scl, uint8_t interruptPin,  void (*interruptFunction)());

And the code become like so

#define INTERRUPTED_PIN D7
 
void ICACHE_RAM_ATTR interruptFunction();
 
// initialize library
PCF8574 pcf8574(0x38, SDA, SCL, INTERRUPTED_PIN, interruptFunction);

Hi g,
Well done! The project looks clean and well-designed, with the PCB neatly housed in the box. The solar panel and antenna add a practical and professional touch. If you’d like to share it on the site, I’m happy to help!

Hi,
try to put 5v on power and 3.3v on logic level.

Hi aleemont,
I think to change speed, you must change the Air data rate. If you want to change the baud rate (I don’t remember very well), you must also set the baud rate on the initial constructor.
By default, It is set to 9600.

LoRa_E220(byte txE220pin, byte rxE220pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600);
LoRa_E220(byte txE220pin, byte rxE220pin, byte auxPin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600);
LoRa_E220(byte txE220pin, byte rxE220pin, byte auxPin, byte m0Pin, byte m1Pin, UART_BPS_RATE bpsRate = UART_BPS_RATE_9600);

Try and give me a feedback.

Hi syrinx,
sorry but I have some issue on some libraries and some pending think to complete, I don’t have so much time.
I hope so be more free and work on It, but It’s very difficult.

Hi Elkez,
you must import esp_sleep.h lib.

#include <esp_sleep.h>

Hi a1ro,

You can find some helpful information on this topic in this article.

For your setup, I recommend configuring each client in fixed transmission mode, targeting the master device. Each client can send a structured message containing the identifier (name or code) of the remote device along with the event value.

The master will read the incoming data, use the identifier to distinguish the source device, and then map and save the corresponding event data. This approach will ensure that each sensor or switch is uniquely identifiable on the master device.

If you have more questions, feel free to ask!

Best,
Renzo

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

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"
