💬 Building a WiFi Gateway using ESP8266

[DenisJ]

Hi there all,
I'm new here and for first think I'll like to thanks a lot for this wonderful MySensors

I just folow step-by-step the guide here: Building a WiFi Gateway using ESP8266

• use all this on a NodeMcu
• I opened the sketch from Arduino Ide from File>Examples>My Sensors> GatewayESP8266
• I edited my WiFi credentials, compiled, and write it on the NodeMcu
• I opened the serial console and watch...

This is what I see on the NodeMcu log:

2216 GWT:TIN:CONNECTING...
scandone
state: 0 -> 2 (b0)
3982 GWT:TIN:CONNECTING...
state: 2 -> 3 (0)
state: 3 -> 0 (12)
reconnect
5068 GWT:TIN:CONNECTING...
6096 GWT:TIN:CONNECTING...
7124 GWT:TIN:CONNECTING...
scandone
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 0 (12)

This NodeMcu was always connecting on my WiFi LAN.
Someone can help me please ?

Thanks in advance
Denis

I finally understand with was the problem...
My WiFi Mesh LAN accepted only 802.11.g+n radio... now that I have set 802.11.b+g+n it's ok
Strange this think cause an all other WiFi Arduino schetch the 802.11.g+n radio was always accepted.

Anyway... now it's work :-)

Hi,
I have a small problem: I am using the Gateway Mysensor EPS8266 WIFi.
Everything is correctly working except the leds:

in the code mysensor code , there is:
// Flash leds on rx / tx / err
// Led pins used if blinking feature is enabled above

define MY_DEFAULT_ERR_LED_PIN 16 // Error led pin
define MY_DEFAULT_RX_LED_PIN 16 // Receive led pin
define MY_DEFAULT_TX_LED_PIN 16 // the PCB, on board LED

I replaced by:

// Flash leds on rx / tx / err
// Uncomment to override default HW configurations
#define MY_DEFAULT_ERR_LED_PIN 1 // Error led pin
#define MY_DEFAULT_RX_LED_PIN 3 // Receive led pin
#define MY_DEFAULT_TX_LED_PIN 4 // the PCB, on board LED

and it does not work: the LEDs are always half-on.

can You tell me if these pins are used for other things and only PIN16 is available for the user ?

Thanks for your help

Gerard

Hello,
I have been using MySensors for a long time. First with serial gateway now with ESP8266 gateway. For months everything worked fine except for small dropouts. Due to dropouts I wanted to switch to current development branch, since then I can not get the gateway to work.
The ESP delivers only the following output:

 ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x4010f000, len 3460, room 16 
tail 4
chksum 0xcc
load 0x3fff20b8, len 40, room 4 
tail 4
chksum 0xc9
csum 0xc9
v00051da0
~ld

I use ESP07 with RFM69 and Standard Sketch. Compiled the code with Arduino IDE as well as with VS code, always with the same result.
I disconnected RFM69 and checked the supply voltage. Have even used other calculator.
Have also tested ESP12e.
Erase Flash I have also already done.
However, when I run other code on the ESP, it runs without problems.
Erase Flash I have also already done.
I just don't understand it.

@Zwer2k please don't crosspost!

[Zwer2k]

Sorry for crosspost.
I found out that the error was due to too new version of espressif8266. I had version 3.1.0 installed, but MySensors seems to work only with versions < 3.0.0. Otherwise the error comes up. Unfortunately I did not find any hint about this anywhere.

Hello! I'm trying to run ESP8266 gateway with nrf24l01 radio module, but when I run it I don't see any logs, I've enebled debugging mode, but still no logs (and it doesn't run gateway either). I've checked connection between this board end esp32 - they communicate well. Don't know what to do else.

[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

[Bogusz Jagoda]

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.
