[SOLVED] ESP8266 WiFi Gateway trouble - pm open, type:2 0

[Strixx]

Hello,

Help needed. I am trying to build a WiFi gateway using NodeMCU. Actually I built it a year ago and it was working fine. But then this hole projekt was suspended, and brought to life again now. But I am not able to get the GW wroking.
I am using Arduino IDE 1.8.5 and have tried with both MySensors library 2.0.0 and 2.1.1. Without any differens.

This is my code:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 9600

// Enables and select radio type (if attached)
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#define MY_GATEWAY_ESP8266

#define MY_ESP8266_SSID "wifi_n2@home"
#define MY_ESP8266_PASSWORD "XXXXXXX"

// Enable UDP communication
//#define MY_USE_UDP

// Set the hostname for the WiFi Client. This is the hostname
// it will pass to the DHCP server if not static.
#define MY_ESP8266_HOSTNAME "MySensor_GW"

// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
//#define MY_IP_ADDRESS 192,168,2,50

// If using static ip you need to define Gateway and Subnet address as well
//#define MY_IP_GATEWAY_ADDRESS 192,168,2,1
//#define MY_IP_SUBNET_ADDRESS 255,255,255,0

// The port to keep open on node server mode
#define MY_PORT 5003

// How many clients should be able to connect to this gateway (default 1)
#define MY_GATEWAY_MAX_CLIENTS 2

// Controller ip address. Enables client mode (default is "server" mode).
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere.
//#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 68

// Enable Inclusion mode button on gateway
//#define MY_INCLUSION_BUTTON_FEATURE
// Set inclusion mode duration (in seconds)
//#define MY_INCLUSION_MODE_DURATION 60
// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3

// Set blinking period
//#define MY_DEFAULT_LED_BLINK_PERIOD 10

// Flash leds on rx/tx/err
// Led pins used if blinking feature is enabled above
// Internal LED is PIN 16
//#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 = 16

#if defined(MY_USE_UDP)
#include <WiFiUdp.h>
#endif

#include <ESP8266WiFi.h>

#include <MySensors.h>

void setup()
{
}

void presentation()
{
	// Present locally attached sensors here
}


void loop()
{
	// Send locally attached sensors data here
}

And here is the serial output:

0;255;3;0;9;Starting gateway (RNNGE-, 2.0.0)
0;255;3;0;9;TSM:INIT
0;255;3;0;9;TSM:RADIO:OK

chg_B1:-40
0;255;3;0;9;TSM:READY
f r-40, scandone
...................pm open,type:2 0
...................................................................

No matter what I tries in the code (static/non static IP) it is the same output.
Any ideas about what is wrong?

@Strixx I can't see anything wrong. The serial output looks fine.

Could you describe what you expected to see?

[Strixx]

I don't know what I except to see. Don't remember how it looked a year ago. But at least an assigned IP (I have seen this output in the forum searching this)

I can't ping it. I can't telnet. I can't see it in my router. And my controller can't find it.

Tried as I wrote with both static and dynamic IP.

[mfalkvidd]

@Strixx yes, you are right. After DHCP the output should say something like this:

connected with Mr-IoT.com, channel 5
dhcp client start...
.....ip:192.168.1.204,mask:255.255.255.0,gw:192.168.1.1
.IP: 192.168.1.204

Could you comment out #define MY_RADIO_NRF24 and disconnect the nrf to see if the problem is related to radio?

[Strixx]

@mfalkvidd I've tried disconnected the radio and comment out the radio. Still the same.

I googled the phrase "pm open,type:2 0" and all hits seemed to refer to problems. So I assumed it was some kind of error message. Since I can't find any documentation of the initial output in the serial interface, and I haven't got the time to go through all the source code.

I started building the gw a year a go, and then it worked. Then I put it on a shelf waiting to get the time to build some sensors. Two weeks ago I started with this project again. And the only thing changed is I now have a new computer. Same router (but uodated firmware), same server, same gateway (Domoticz).

So I thought it was the usb port not being able to power the Node MCU. To day I plugged in a powered usb hub, but that made no difference. Then tried recompiling with the latest MySensors library, then "down grading". Still the same.

@Strixx said in ESP8266 WiFi Gateway trouble - pm open, type:2 0:

I doubt the search results mean that "pm open,type:2 0" indicates a problem. People don't usually post detailed logs when their projects are successful, they post them when they have trouble.

This is the output of my esp8266 when commenting the nrf define. I also changed the wifi ssid and password, but everything else is exactly like your post above (I copied the code you posted). Result:

The connection is also verified in the Arduino IDE Serial Monitor:

Could you post the full output when doing the same on your gateway?

[Strixx]

Well off course you are right about not posting output when it works. But then again Google wont find many answers on that phrase.

Any way. Last night I updated uupdated to MySensors library 2.1.1, and tried again, without any luck. I did notice that I got some errors about invalid library in the IDE after switching to 2.1.1. But there was no luck, still no assigned IP. Tried to change to a different AP. Nothing

So this morning I gave it a new go and change the code back to static IP, and now it is working.

connected with wifi_2@home, channel 11
ip:192.168.2.50,mask:255.255.255.0,gw:192.168.2.1
.IP: 192.168.2.50

pm open,type:2 0
0;255;3;0;9;Client 0 connected
0;255;3;0;9;Client 0: 0;0;3;0;2

So I cant find any pattern in this. I will do some more testing during the day to see if I can find what went wrong before..

[gohan]

Why don't you give a try to mysensors library 2.2?

[Strixx]

Ok... Sorry for bothering you... I have been testing several things now for an hour. And I found what was causing the errors, and it was my Asus router. A year ago when started this project apparently set up an dhcp rule for the gateway binding it to a certain ip when connecting. Some how this is the cause for not getting any IP at all.

Because now, when removing this rule, I am able to connect and receive IP adress in dynamic mode on.

It is strange because I have allot of other things that is getting manually assigned IP from the DHCP in the router, and they all works. But I guess this is to hard for me to find why the gateway is not working with this settings in the router..

Now I will get back to testing inclusion mode and traffic leds on the NodeMCU wifi gateway.

[gohan]

That's odd as I use dhcp reservations too without issues

[Strixx]

It for shore is. And what is even more strange is that adding a new manually assigned IP now is working.
Can't explain it. The router is a Asus RT-AC66U.
