ESP8266 WiFi gateway port for MySensors

[D_dude]

update,
the error changed to "rst cause:4, boot mode:(3,6)" once i added a capacitor.

These ESP's seem to walk in mysterious ways...
A lot of people have them, running without any issues (including myself and hek) and some people can't seem to get them to run stable.
On the net, a lot of stability/reset issues are are claimed to have a relation to power supply.

I even tried to power it using a USB cellphone charger, but i was unable to telnet so that rules out the power issue

There are a lot of assumptions in this sentence ;-)
What current rating is the cellphone charger? I'd advise one with at least 1amps, and a stable output.
Not being able to telnet to the gateway can have more issues then just the ESP crashing...

@Yveaux
Thank you for the response.

As for the cell phone charger, I'm using a tablet charger Specifically original HP stream 7 charger, and it is able to provide more that 1amp. I Will try to use other charger/power supply to see if that helps.

PS: I reloaded the gateway sketch and the error went back to boot mode (3,7) even with cap present.

[Yveaux]

@D_dude I searched the net for a description of reset causes and boot modes but failed to find one.
I have no clue of what they mean.

[D_dude]

@Yveaux
thank you for your assistance. I will try adding some debug in the code on the weekend to see what exactly is not running and possibly causing crash.

I got a suggestion here to erase the flash before flashing. Haven't tried it yet, but it might help you @D_dude

[D_dude]

@mfalkvidd
Thank you, i will try this and post results.

[D_dude]

@mfalkvidd
tried erasing the flash using the method suggested but doesn't seem to be working for me. same result.
Thanks for the tip though.

[mfalkvidd]

Too bad. Thanks for posting your results.

here is my ESP8266 wifi gateway installed in wifi repeater box, taking the advantage that its has a 5 volts power supply.

@luisgcu Nice housing!
Thanks for the pics!

I'd been using the ESP gateway for several weeks, but recently was having trouble adding a new sensor I am developing.

Since the copy of dev I built it with was now out of date, I went ahead and updated... still wasn't working right so while I had the serial link to it I checked and noticed it was crashing and cycling. It would work for hours, until I fired up my new node, then crash about immediately. A few dozen debug(PSTR())'s later, I found a cause.

In core/MySensorsCore.cpp the result of _msg.getConfig() is dereferenced in a comparison, and it's possible it could return NULL ( like when it's a new node ). I put a check around that and it's not crashing anymore. Which is more than what I can say for my new sensor node....

I have not tested this change with an AVR.

I submitted PR 264.

[mfalkvidd]

Great work @soward !

[D_dude]

on some basic debugging, seems like my sketch is crashing in setupGateway.

infact even adding a print statement, it only prints first 3 chars.

My question is setupGateway takes output as an arg, which in turn is a function, should there be some parameters for this function?
also "Serial.print(serialBuffer);" does not print anything i added prints above and before and they don't show up either.

  va_end (args);
  Serial.print("A1");
  Serial.print(serialBuffer);
  Serial.print("A2");

any suggestions?

[Yveaux]

@D_dude flush the serial output after each print.
The ESP will output the serial data in the background while your programm continues and then it crashes.

Hi,
I'm getting all the time this:

Connecting to layla
......Connected!
IP: 192.168.0.102
0;0;3;0;9;gateway started, id=0, parent=0, distance=0

Then it got stuck so I do reset and getting this in loop:

Means there's something wrong with your nRF communication. The WDT reset following this is normal.

i have been using wifi gateway with Domoticz controller without any problems until recentely. After the last update to beta version of the controller, the gateway crashes when the controller request gateway version:
Gateway startup complete.
Client 0: 0;0;3;0;2;

Exception (28):
epc1=0x4000bf80 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

ctx: cont
sp: 3ffebf60 end: 3ffec1f0 offset: 01a0

I have tested with telnet client with the same request and it was ok. Then I saw that the request from controller was terminated with only <LF> and not with <CR><LF> and this is why it crashed. I have added the following to the sketch:

•    if (inChar == '\n')
    {  
      if (inputString[i].string[inputString[i].idx-1] != '\r') { // if the last char is not CR then add it
      inputString[i].string[inputString[i].idx++]='\r';
     }
      // a command was issued by the client
      // we will now try to send it to the actuator
  

and now it seems to work.
Is this the right way to go?
Thanks
