Hi,
you can simply reduce this number.

Hi Gilles,
please enable debug and send me the result.

Please, can you reupload the file.
Thanks

Hi Jeff,
if the wiring It’s ok, the only known problem can be the power supply insufficient, or the device broken.

Hi Abdelkader,
sorry for the late response, but I must fix the notifier.
For micropython I write the specified library

https://github.com/xreef/EByte_LoRa_E32_micropython_library
https://github.com/xreef/EByte_LoRa_E22_micropython_library

also for python

LoraWAN It’s a proprietary standard, I think the better solution is to use an MQTT broker and use It (like AWS one).

Hi George,
I think the simple solution is to send a fixed TYPE and decode it to the receiver.
The message isn’t applicable on binary stream.

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); 

Bye Renzo

[Renzo Mischianti]

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

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.
Bye Renzo

[Renzo Mischianti]

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.
Bye Renzo
