ESP8266 WiFi gateway issue

[snow]

Hi,
I have one battery powered node build on Arduino Mini Pro 3.3V with combined 2 sensors DHT11 and BH1750. The node is working OK and give me correct values from sensors on Arduino serial console.

The output from this node connected to Serial gateway is also OK.

And this is the output from the same node connected to ESP8266 gateway. As You can see, only the first output of LIGHT_LEVEL is correct.

Could anyone check this?

@snow Could be a 8 (ATMega32) vs. 32 bit (ESP8266) issue.

1032       = 0x0000 0408
1107297279 = 0x4200 03FF

The lower 16 bits are more or less equal.
Could you post the serial output of the ESP8266 gateway for such a set of LIGHT_LEVELs and a screenshot of MYSController as you did before ?

MsgID#32 is from the serial gateway, as I understand it...

@Yveaux I have made another test on two gateways at the same time. Here is the results.
Serial gateway (Arduino NANO)

ESP8266 gateway (ESP-07)

I suspect a problem with the length or definition of variables, but I'm not a good programmer. ;)

1107296631 - 383 = 0x4200000
1107296622 - 366 = 0x4200000

Msg54 again shows subtype 22, which is for V_HVAC_SPEED. It occurred on both the serial gateway example (top of thread) and the ESP. It seems to mess up the message at the node level. Perhaps not a problem with the gateway.

Agree. Possibly a variable somewhere that has a different size on ESP.
Hopefully tonight I can have a better look.

Pretty sure I found the cause: the messages exchanged between sensor and gateway contain int types.
These have a size of 2 bytes on Arduino and 4 bytes on ESP.
An int sent from the Arduino is sent as 2 bytes, but the ESP expects 4. The upper 2 will be filled with garbage.

Still a hypothesis which has to be verified & fixed.
To be continued!

[Yveaux]

@snow Please try the code in the development branch , where hek did an excellent job to standardize on datatypes being exchanged between nodes.
This will probably solve your issue.

[snow]

The development version is working OK :satisfied:
Thanks guys for your hard work.

[Yveaux]

@snow great to hear!
Glad I could help (and my hunch was correct :-) )

[Hoffan]

@snow

Did you use the Development version of the ESP8266 Wifi gatewavy or for the sensor

[hek]

@Hoffan
You should probably use it on both sides to be sure to get the same size on the data types.

[Hoffan]

All the sensors that i have include before i upgrade the ESP8266 Wifi GW is now working

But its not working to include more, Nothing happens in Veran when i press start
but the gateway say this

0;0;3;0;9Client 0: 0;0;3;0;5;1t version

every time i press start

At the moment I only changed the gateway. It's already solved my problem with incorrect values.

[Hoffan]

@snow

But is your include button working now?
Or maybe you don't use Vera as a controller

[hek]

@Hoffan

The print looks a bit weird. I'll have to do some tests.

[snow]

@Hoffan No. I'm using DomoticZ

[Hoffan]

@hek

That sounds good, Just ask if you want me to test something..

[Hoffan]

@hek

Any News here ?
