Hi Lev,
the project is subdivided into 2 parts, the first is the link in your post, and the second is the web interface that is in another repo.The “heartbeat functionality” can be managed with a broadcast message with the address set in the E32 fitted in the gateway. In the message return, you must check if it’s an acknowledgment and add the information passed in a WebSocket message.
The second is less simple, because the WebInterface is a React, Typescript, Redux framework, so you must know at least React, here an example of Message receiver box.
The only consideration is that in the project, we use a push server hosted in the ESP32 that implements WebSocket. To create a fully working gateway, the best practice says that you must use an external MQTT server, like the LoRaWAN implementation (It’s a simple standardization of a gateway to ask for money from the people).
So my advice is to implement all the needed functions in the “server” part; if it’s interesting and usable, I think some people will follow you to help on WebInterface.

It’s interesting if you want, I can change your role as an Author, and I’d be happy if you want to write an article about that on the site.
Keep in touch, RenzoHi Mariano,
Thanks a lot for your feedback.It’s strange my version works with SdFat as the key to manage the connection, not SdFs, but I think It can be the style of programming that determines the problem; the interaction method must be the same as the library.
Thanks again RenzoHi g0730n,
you must create a repeater specified for your kind of network.If you create a transparent transmission network, you must use a transparent transmission and set the devices on the same ADDH ADDL and CHAN, but every time you repeat a message also, the sender receives It.
Ebyte LoRa E32 device for Arduino, esp32 or esp8266: fixed transmission – 4
For the fixed transmission you must create/manage a protocol or similar.
For example, you want to repeat a message that all devices must read: you must send the message to the repeater, and the repeater sends a broadcast message.If you want to send a message to a specified device, you must send the message to the repeater (or broadcast), and the repeater reads some information inside and sends a specified message.
There isn’t a specified solution.
For example, E22 has the repeater function, but It’s quite complex; here is a schema.

Thanks, Renzo
Hi,
I understand, as you can check here,you must close the opened structure.

Yes, there is a memory leak. You must discover which part of the code generates that.
Normally I’m going to add a lot a Serial.print to examine every part of the code.But, when you program, also in the embedded env, It’s a best practice to encapsulate every functionality in functions because when the function ends, It works, and every variable inside is released.

Hi Woto,
It seems that there is a character that’s not encoded correctly, which kind of message do you send?
Bye RenzoHi L33t331,
It seems to be a memory leak problem; try to examine the memory usage and give me feedback.
Check also the power supply, but It isn’t probably.
Bye RenzoHi Woto,
if you don’t add the sleep time, the processor gets 100% of usage and can freeze.If you receive more than one message, the messages are stored in the buffer of E220, and when you read them, you receive the two messages at once.
Bye Renzo
Haa!! perfect.
But also the other module works better at 5V power supply; if you use 3.3V, the distance is reduced drastically.
Bye RenzoI don’t know if I explain well.
Suppose you put the code with the operation of sending and relative variables inside a function. In that case, all the variables and operations executed and allocated inside the function remain inside the function (like Fight Club).
So this can prevent the memory leak.
