Hi Fabiooo,
if you have a (minimal) memory leak, probably write over the memory location of the received message variable or at the sending time.

hi Fabioo,
It’s very strange; It’s possible that there are some issues with the power supply.
Or a bad usage of memory allocation?

Thanks a lot. Your work is precious.

Sorry Woto,
if you set the ADDH, ADDL, and CHAN with the same value, you have configured the devices to communicate in transparent transmission.

To use fixed transmission, you must set a different ADDH or ADDL and send the message from the first by setting the receiver’s destination address.

So, if you have configured the sender

ADDH = 00
ADDL = 03
CHAN = 18

you must configure the receiver

ADDH = 00
ADDL = 04
CHAN = 18

and in the sender
ResponseStatus rs = e220ttl.sendFixedMessage(0, 4, 18, "Hello, world?");

But I think you must check the articles, they can be more clean.

Hi woto,
you have configured the Address and Channel for transparent transmission and set fixed transmission.

Follow these tutorials to send fixed message

this is for E32 and micropython but you can get some ideas

Hi woto,
you don’t need to change the library.
You can find how to use the library for e32 (similar to E220) in this article.
EByte LoRa E32 & MicroPython: a detailed look at configuration – 3
I create a specified tutorial for E220 soon.

code, configuration = lora.get_configuration()
configuration.CHAN = 18
code, configuration = lora.set_configuration(configuration)

Hi MAWMN,
not inside the library, but I think you can check the millis(), and if you already have a click in a specified interval, you can abort the previous action and activate the new one.
But pay attention, if you already clicked one and after that interval, no other action was activated, you must execute the click function.

Hi Carcela,
to create a network, you can follow the instructions in this article

you can also use the repeater function to manage devices with a lot of distance

Hi Orhan,
you must connect the AUX pin and try to manage the air data rate and baud rate, but the frequency can be variable because of FEC and waiting for the transmission, so disable It.

Hi Srill,
haaa perfect!
No, I think it’s not possible, they use a different chip to implement the communication.
Bye Renzo

[Renzo Mischianti]

Hi Srill,
you must pass the reference of Serial.

LoRa_E32 e32ttl(&Serial2, 15, 33, 32);

Hi,
check if another process uses the port.

netstat -an

Hi,
remove all unneeded lines like

SoftwareSerial mySerial(D2, D3);

pin declaration etc. and retry.

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.

tools\xtensa-esp32-elf\esp-2020r3-8.4.0\xtensa-esp32-elf\bin\xtensa-esp32-elf-addr2line.exe -fe C:\MYPROJECT\build\MYELF.elf 0x4000c269:0x3ffb7810 0x400d5327:0x3ffb7830 0x400d59a2:0x3ffb7850 0x400d600f:0x3ffb7b20 0x400d5039:0x3ffb7b40 0x400d3f17:0x3ffb7b80

or you can use Arduino IDE plugin.

Bye Renzo
