ESP8266Wifi Gateway won't connect

OldSurferDude

@dpcons @hard-shovel @paqor @chrishiscox @mfalkvidd Hi all,

I saw this and got excited that I could use my NodeMCUv1.0 as a MySensors Gateway. I made sure I had the latest MySensors library (2.3.2) and ESP8266 board (3.0.2). I successfully ran a couple examples, first file-->examples-->ESP8266-->Blink then file-->examples-->ESP8266-->interactive (with my ssid & pass), the latter with serial monitor at 115200 baud.

I ensured that my nRF24l01 was functional by connecting it to an Arduino Nano and running the scanner program.

I connected my nRF24l01 to my NodeMCU, both having pins, using new 10cm 7 conductor ribbon cable. (I have successfully used this type of connection to an RPi)

The program ... I copied the program from this page and applied my ssid and password. Nothing ... I suspected that this code is a node template, not a the gateway program.

On that same page was the instruction "Open the WiFi gateway in the Arduino IDE (File -> Sketchbook -> Libraries -> MySensors -> Esp8266Gateway)" I didn't find "Libraries" under "Sketchbook" I a file of the same name at (File -> Sketchbook -> Libraries -> MySensors -> examples --> Esp8266Gateway) which is the same file.

I tried putting into setup the line

Serial.println("com check");

but nothing came out on the console.

I think I'm at the same place as @dpcons

update: rechecked my radio with the RF24 "getting started" program and found the radio good. Updated my Arduino IDE. Still not working.

@OldSurferDude @dpcons Hi all,
The sample sketch could also be found using (File -> Examples -> MySensors -> Esp8266Gateway

As MySensors version 2.3.2 and ESP8266 core 3.0.2 combination does not work you need to change one or the other versions.

The simplest is to roll back the ESP8266 Core version to 2.7.4 and keep the MySensors 2.3.2 version
(Tools -> Board -> Board Manager)
Enter ESP8266 in search bar, then click within the ESP8266 data info box, click the select version pulldown.
Select 2.7.4 and then click Install.

Other option is to update the MySensors library to the development version 2.4.0-Alpha but that has to be done manually.

OldSurferDude

@hard-shovel Thanks! Now I'm getting output to the monitor. I think I need to set up the IP address and the port 1883 for the MQTT broker. How is that done? I am also getting data from my Arduino node sensors :) I see "controller" but when I change that to my broker's address I get streaming ETH FAIL

OldSurferDude

The port was set to 5003 and setting it to 1883 (the default MQTT broker port) it now seems to work

hard-shovel

@OldSurferDude If connecting to a MQTT Broker i would have expected you to use the GatewayESP8266MQTTClient sketch.
as this is already setup with correct Port 1883 for MQTT and the publishing and subscription topics.

I did a quick test of a GatewayESP8266MQTTClient sketch with mosquitto and it works fine for me.

OldSurferDude

@hard-shovel While it all seemed to be working, it appears that the ESP8266 MySensors Gateway was not passing the data onto the MQTT broker. Working, meaning that data from the Arduino sensors were getting to the Gateway, but that data was not getting to the broker. Here are some lines of the debug output:

6217818 TSF:MSG:READ,133-133-255,s=255,c=3,t=7,pt=0,l=0,sg=0:
6217883 TSF:MSG:BC
6217903 TSF:MSG:FPAR REQ,ID=133
6217936 TSF:CKU:OK,FCTRL
6217962 TSF:MSG:GWL OK
6218281 !TSF:MSG:SEND,0-0-133-133,s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=NACK:0

Also, as an indication that data was not being passed from the Gateway to the broker, I had reset my MQTT Broker and subsequently monitored it with MQTT explorer. The topic "mysensors-out" was not created.

I shut down the ESP8266 MySensors Gateway and restarted the my original one that is running on an RPi. Everything started running as expected.

Thus, my conclusion.

OK, so why isn't the ESP8266 MySensors Gateway passing on the data?

OldSurferDude

@hard-shovel I try the client

OldSurferDude

@hard-shovel client worked for me, too. That is, it sent the message "2.3.2" to topic "mygateway1-outx/0/255/0/0/18"

OldSurferDude

@hard-shovel I tried the client and it did indeed send the MySensors version message. But it does not pass along the messages from the Arduino nodes.

hard-shovel

@OldSurferDude have you set the MQTT user and MQTT passwords in the sketch and uncommented them as well?

// Enable these if your MQTT broker requires usenrame/password
//#define MY_MQTT_USER "username"
//#define MY_MQTT_PASSWORD "password"

// Enable these if your MQTT broker requires usenrame/password
#define MY_MQTT_USER "MQTTusername2022"
#define MY_MQTT_PASSWORD "MQTTpassword2022"

what does your debug log look like?
This sample is not connected correctly to the MQTT Broker

@hard-shovel My MQTT broker does not require them. Should I uncomment and leave them blank?

hard-shovel

@OldSurferDude You should leave them commented if not required.

I have just tested with a new install on windows of mosquitto with config file for anonymous access and it is working fine with them commented out.

what do your gateway debug logs look like?

@hard-shovel This is what I'm getting (with no nodes connecting to gateway)

@hard-shovel I created a faux nano sensor and used nRF24L01 channel 121 to communicate to the gateway. Here is my NodeMCU ESP8266 code with all comments taken out:

@OldSurferDude you are (at least) missing #define MY_GATEWAY_MQTT_CLIENT.

The sketch you are using is instructing MySensors to create an ethernet gateway.

Example sketch for esp8266 mqtt: https://github.com/mysensors/MySensors/blob/master/examples/GatewayESP8266MQTTClient/GatewayESP8266MQTTClient.ino

@mfalkvidd said in ESP8266Wifi Gateway won't connect:

#define MY_GATEWAY_MQTT_CLIENT

That was it! Thank you!

@mfalkvidd Because I see that the example has a presentation() routine with the comment "// Present locally attached sensors here" I made the assumption that the gateway could have local sensors. I described a local sensor

// local sensor information
#define MY_NODE_ID 3
#define CHILD_ID_GATEWAY_FAUX_SENSOR 0
MyMessage msgFauxSensor(CHILD_ID_GATEWAY_FAUX_SENSOR, V_LEVEL);
int fauxSensorValue = 0;

and put the data acquisition code in the loop:

// Send locally attached sensors data here
 send(msgFauxSensor.set(fauxSensorValue++));
 Serial.print("Value sent: ");Serial.println(fauxSensorValue);
 delay(30000);

Lo and Behold! This data was being found on the MQTT broker! Albeit the NODE_ID was not 3 as defined, but 0. This makes sense because the NODE_ID of the gateway is zero.

Previously, I had my gateway running on an RPi. My question is, can I put a presentation() routine and data acquisition of the gateway running on my RPi?

delay(30000);

A delay in the gateway will make the gateway freeze. It will not handle incoming messages (not from the mqtt broker, not for any nodes). Use wait() instead.

Yes, it should work. The file to edit is https://github.com/mysensors/MySensors/blob/development/examples_linux/mysgw.cpp
