Hi George,
yes you need to pass It in the message.

Hi George,
for a structure, with a fixed size, you do not need to identify the end of the struct, you already know the size.
If you have some different messages, you can use a simple trick like this (read the first part of the struct to understand the type).

Ebyte LoRa E220 device for Arduino, esp32 or esp8266: manage Wake On Radio and sends structured data – 5

Hi George,
I don’t know in detail, but I think the use a personal encryption algorithm, not a standard one.
The size of the message didn’t change.

Hi perca23,
I think that I did an error, the 915 version started from 900 but the 900 does not start from 850 (like E220) but start from 862.
I’m going to fix It.
Thanks Renzo

Hi Ludophot,
have you try to set new Serial like so?:

HardwareSerial SerialPort(1) 
SerialPort.begin(9600, SERIAL_8N1, 16, 17);

I think It isn’t possible, but I can’t find anything about that.
Bye Renzo

Hi,
You can find an example communication here.
https://blog.zesanglier.fr/2023/02/11/communiquer-entre-un-module-ebyte-e32-et-un-module-ra01-02-sx1278/

The algorithm is quite simple.

Hi Sahar,
I’m out for 2 days when I return, I will try to find It.
But surely It’s more simple to use the same kind of device to do a project, you can communicate with the transparent transmission, but a fixed one can be a problem.

Hi Sahar,
I think there are some problem.
First three frequency is
FREQUENCY_900
then you must set the same frequency of the devices in configuration.

But most important is that EByte LoRa use a cryptography system that do not allow the communication from different devices.
But the algorithm was quite simple, so if you want I can search it and post here.

Hi xwingmll,
hehehehe.. sometimes the solution is to power off and power on.
Thanks, sorry for the issue I insert, but It’s a work in progress.
Please keep in touch if you find some other problem.
Bye Renzo

[Renzo Mischianti]

Sorry,
I fixed the regular expression, and I re-tested the library with an esp32 devkit v1 and It’s works correctly, I can reproduce your error by putting an AUX pin or M0 M1 pin wrong
Check the wiring or power supply.

Hi xwingmll,
when the device return data size does not match It’s a high probability that you wrong set M0 and M1 pins, or power supply issues.
Bye Renzo

[Renzo Mischianti]

Azz, no sorry, I check a wrong project 😛

Hi mr.big,
thanks for your help, but I think you get an older version of i18n, please use this to add your language.
Thanks again Renzo

Hi Mike,
Probably pcf8474 maintains the state with the continuous current.
But my library restarted the pcf in Setup and I think you lost all.
Bye Renzo
