ESP8266 MySensors Gateway Crashes when Node Connects

[Luppie]

Today I've build a ESP8266 MySensors Gateway.

The gateway starts up and I can connect to it with my Domoticz Controller.

What I tried my self:

• placed a decoupling capacitor on both radio's
• mounting the PCB's on a protoboard to minimize the distance between the controller and the radio by nit using dupont cables.
  

What am I missing and how can I get this setup to work ?
Any help/suggestion is appreciated.

[Yveaux]

Power supply seems to be a recurring problem with ESP8266.
I assume you power the ESP board through the USB connector?
Do you power it from your PC then?
USB 2.0 can supply a maximum power of 500mA, which is on the edge for ESP.
Try powering the board from a 1Amp minimum supply and see if things improve.

[Luppie]

I did power it from my PC, so i tried your suggestion and powered it with an 'official' Raspberry Pi 2A power adapter. IMHO this is the most stable 2A power adapter.

Unfortunately it still crashes and reboots.

[vickey]

I am using mysensor 1.5.1 ESP8266 mysensor gateway. But It is not starting up. I am using 2A power supply. Here is the log.

May someone help me?

[Luppie]

I also tried to use 1.5.1, but the ESP8266Gateway sketch won't even compile, so I'm stuck with no Gateway.

[Luppie]

Yesterday I installed 1.5.1 Development.
Today I installed 1.5.1 master

Still having the same crash when a sensor connects to the gateway.

To rule out if the problem is on the controller side, I installed a different controller (MajorDomo) to see how the gateway reacts.

Unfortunately the gateway still crashes.

[twisted]

Well I'm sort of glad, I thought I was the only one with this issue. I have tried numerous power supplies, including one I am sure is very stable and can supply the required load.

I am using 1.5.

[hek]

Sorry to hear about your troubles. Very strange. My ESP gateway seems very stable here, shuffling messages back and forth. I just feed in from my mac (but with vanilla NRF-radio on it).

Yesterday I installed 1.5.1 Development.

Guess you mean 1.6.0-beta? That is what I mainly run here now...

What happens if you simply use netcat to send messages to the ESP?

> nc 192.168.1.xx 5003
(then send the serial messages..)
42;1;1;47;0;Hello

[Luppie]

When I use a telnet session from Putty, the crash does occur.

When i connect from linux with nc, the crash doesn't occur.

What could be the problem ? I exactly followed the build instructions. I even bought the hardware from the ebay-links provided.

[hek]

Looks like you're sending some trash characters when connecting with telnet (just after "Client 0"-print).

I have no idea what that crap is.

But as it works with nc you must be doing something strange...

[mfalkvidd]

telnet is more than just a TCP connection. Not much more, but it will always send some extra characters. Netcat is a pure TCP connection.

[Luppie]

Thanks hek & mfalkvidd.
Reading your replies made me think that maybe the problem isn't the gateway, but the sensor sending some crap.
I will build a new sensor toninght and test it.

[Luppie]

Hmmm, I've build the most basic actuator "BinarySwitchSensor" and again when it connects, the gateway crashes. I'm totaly lost here.

[hek]

So it crashes both when controller connects to gateway or when it receives a radio message?

[Luppie]

When no controller is connected and a message is received it doesn't crash.

It only crashes when a controller is connected and the gateway receives a radio message.
(I used the tempsensor sketch and the binaryswitch sketch to test)
(But the testmessage : 42;1;1;47;0;Hello didn't crash the gateway)

Right now I just uploaded the SerialGateway sketch to 1 of my sensors and that is working correctly with my Domoticz Controller. But I still prefer a wifi gateway.

[Tronix]

@Luppie Hi. Have you ever been able to solve this issue? I have the same here.

Tronix

[Luppie]

Nope, I never resolved it. So I've build a USB gateway, thats is working great for 4 months now.

[Tronix]

@Luppie Ok, thanks. I also have the USB and LAN gateway running. But it would be very helpful having the WIFI version on other locations in the house. Thanks anyway.

[Mark Swift]

I also experience a crash... I've tried using master and dev, I see the crash when Domoticz tries to connect to the gateway (Using the MySensors LAN option)... When running without Domoticz, it seems to run fine without issue (watching debug all appears a-okay).

Spent almost the last day trying to work it out, no luck so far!

[hek]

Could this be related to your problems?

[Mark Swift]

@hek I'm not sure as I'm using a nodemcu

[Mark Swift]

@hek Grrrrr, figured it out after a whole day wasted! My board manager had updated the ESP8266 version to 2.1, rolled back to 2.0
