Обмен данными между двумя ESP8266, хоть как то

hugiboss317 · August 24, 2022, 1:53pm

Так и знал что это код нельзя показывать…
Жаль что никакой on-line переводчик не сможет выразить тех эмоций, которые я сейчас испытываю. Нет, я всё сказанное понял, спасибо за ответ. Только теперь вообще ничего не понятно.
Вероятно это значит что если сейчас просто ничего не работает, то через 4,5 месяца вообще ничего работать не будет. Я конечно не уверен как у вас там всё устроено, но помогло это мало чем.

You could obviously put some time and effort into getting Bridge working correctly in Legacy, and there are many topics on this forum that explain how to do that.
However, this will stop working on 31st December, and as Bridge doesn’t work in Blynk IoT, so the time and effort you put into this would be wasted.

That’s why you either need to stick with Legacy and set-up a local Legacy server (which isn’t something I’d recommend) or move to Blynk IoT.

What is it Blynk IoT?

PeteKnight · August 24, 2022, 2:55pm

It’s the new version of Blynk…

Pete.

hugiboss317 · August 24, 2022, 4:20pm

So I use that alredy long time. And what we tolking about?

PeteKnight · August 24, 2022, 4:40pm

Well, you talked about local server, which is Legacy not IoT, and Bridge, which is also Legacy and not IoT.

Posting code snippets, and not providing the information about which version of Blynk you are using - which is requested when you create a topic, means we have to make assumptions, and everything you’ve posted leads to the assumption that you are using Legacy not IoT.

If you want to transfer data from a salve device to a master in IoT the. You can use Automations in some situations.
If Automations don’t provide the functionality you’re looking for then the HTTP(S) API can be used to simulate the Bridge functionality of Legacy…

and…

Ok. That is good. Now maybe U can call some one, who can expain me somesing?

PeteKnight · August 24, 2022, 6:32pm

I don’t understand.

Pete.

hugiboss317 · August 24, 2022, 8:44pm

Что мне делать с этим?
Как заставить обмениваться данными между двумя ESP8266, одна из которых подключена к Blynk?

PeteKnight · August 24, 2022, 9:10pm

Both of the ESPs will communicate via the Blynk server.
They don’t talk to each other directly.

Pete.

hugiboss317 · August 25, 2022, 11:43am

That’s a good thing. Thank you so much for answering me. Can you show me a simple example? Which libraries need to be downloaded/updated? What should be declared and initialized in both controllers? I, at this point, have no idea where to start.

P.S. Looks like I get it. Is it equivalent to a GET request from the web browser’s address bar?

PeteKnight · August 25, 2022, 11:56am

It’s all in the links I provided.

Correct.

Pete.

hugiboss317 · August 25, 2022, 12:17pm

Could You just give me link with exammles?
I understand what you’re talking about. That’s what I need. But I can’t do anything practical… I don’t know what to write.
https://github.com there are no examples on the topic of blynk-server.

PeteKnight · August 25, 2022, 12:36pm

I’d suggest that you post your code and the actual full compiler error message, not just as partial screenshot.
You also need to clarify whether you’re trying to compile this for an ESP8266 or ESP32.

Okay, that appears to be caused by using the wrong quotation mark symbols.

This … "

is the correct symbol. The compiler doesn’t recognise “ or ” as being valid quotation mark symbols.

Pete.

hugiboss317 · August 25, 2022, 6:36pm

Yes you are right. I don’t know how I didn’t notice it.
Which library do I need to include?

The two links in post #8 - the original one for the ESP32 and the second one which modifies that code to work for the ESP8266 in an Edgent sketch.

You’ve clearly followed at least one of them as you’ve copied pieces of my code from there - and created some issues for yourself in the process by not copying all of the relevant pieces.

This error is caused because you didn’t bother to copy the line that begins String server_name =
