💬 Building a WiFi Gateway using ESP8266

[Yveaux]

@Serj-Sam logs are available through serial port. You mention esp8266 and esp32; which one is it?

[mfalkvidd]

@Serj-Sam you mention "connection between this board and esp32". What board are you referring to, and what type of connection? Wifi?

[Serj Sam]

@mfalkvidd I have esp8266 NodeMCU v3. I've connected it to esp32 devkit via nrf24l01 using simple test code where I sending and reading constant string. It's just to exclude problems with nrf24l01 and esp8266.
@Yveaux I don't have any logs through serial port related to the MySensors. When I remove MySensors lib (and the code related to it) I'm able to print messages in setup() and loop() section, but with MySensors lib it stuckted somewhere without logs and do not execute code in setup() and loop() sections.

[Yveaux]

@Serj-Sam you could very well have run into the incompatibility of mysensors with the latest esp arduino core 3.x (see eg https://github.com/mysensors/MySensors/issues/1496)
Easiest solution is to downgrade the esp arduino core to 2.x

[Serj Sam]

@Yveaux said in 💬 Building a WiFi Gateway using ESP8266:

downgrade the esp arduino core

Thank you @Yveaux ! It works now! Have you heard anything about long-term solution? Looks like this will be overwritten once I update MySensors lib.

[Yveaux]

@Serj-Sam there is a pull request included in that pr. Once this is merged it will be available in development, later in the next release.
If you just downgraded the core, that is persistent until you upgrade the core to 3.x again.

Hi,
I would like to add sendSketchInfo to my gateway.
I added

const char* sketch_name = "GatewayESP8266OTA_v3";
const char* rev = "1.01";

at the beginning of the sketch and

sendSketchInfo(sketch_name, rev);

in the presentation part.

but this doesn't seem to work. Am I doing anything wrong? Any suggestion on how to do it right? Many thanks in advance!

[rejoe2]

Use this syntax instead:

#define SN "GatewayESP8266OTA_v3"
#define SV "1.01"
[...]
sendSketchInfo(SN, SV);

@Fat-Fly i also want the answer of this question

Worth noting - use MY_RFM69_NEW_DRIVER define... (2.3.2+)

#ifdef ESP8266
    // For RFM69
    #define MY_RADIO_RFM69
	#define MY_RFM69_NEW_DRIVER
    #define MY_RFM69_FREQUENCY  RFM69_868MHZ // Set your frequency here
    #define MY_IS_RFM69HW                    // Omit if your RFM is not "H"
    #define MY_RFM69_IRQ_PIN    D1
    #define MY_RFM69_IRQ_NUM    digitalPinToInterrupt(MY_RFM69_IRQ_PIN)
    #define MY_RFM69_CS_PIN     D8           // NSS. Use MY_RFM69_SPI_CS for older versions (before 2.2.0)
#endif

Hi,
I'm having trouble compiling the ESP gate code. Can you help me?

I join the question, I have exactly the same problem: .../MyMainESP8266.cpp:95:9: error: 'cont_can_yield' was not declared in this scope; did you mean 'can_yield'?
i found a reference #include "cont.h" in MyMainESP8266.cpp but i can't find 'cont.h'

[Msmax]

@veris25
I installed an older ESP8266 lib v3.0.0 to compile without errors.

[electrik]

You should try downgrading the ESP version below 3.0

[HoseArkadio]

elektryk ....I do not really understand.

[electrik]

I mean the ESP framework version, selected by the board version
