V.2 reset after decoding the first packet on Arduino Nano

[zoomx]

I have compiled and loaded the V2.0 version on an Arduino Nano. I have only corrected the plugin 047 as described in issue #20

I disabled most plugins, leaving only these

define PLUGIN_029 // Alecto V2 (WS3000/DWK2012) 434 MHz.

define PLUGIN_030 // Alecto V1 (WS3500) 434 MHz.

define PLUGIN_031 // Alecto V3 (WS1100/WS1200/WSD-19) 433.9 MHz.

define PLUGIN_032 // Alecto V4

define PLUGIN_044 // Auriol v3

define PLUGIN_045 // Auriol

define PLUGIN_046 // Auriol v2 / Xiron

define PLUGIN_047 // Auriol v4

I made also the correction described in issue #24

I get this

`"29/04/2020 12:40:16",20;00;RFLink_ESP;VER=1.1; "29/04/2020 12:40:24",20;01;Alecto V1;ID=008C;RAIN=0e42;BAT=OK;

It seems that few milliseconds after decoding the first packet the MCU resets

Changed MaxPlugin from 55 to 10, now I have more RAM but get strange results

Changed USB port, same results.

When I use my sketch to capture I get expected results.

Hello again! Can you :

• Disable Alecto V1 plugin
• Disable all but Alecto V1 plugin

And tell me if you reproduce this issue in both cases?

I also suspects IDE... Can you both test :

• Arduino IDE (18.10+)
• PlatformIO IDE

[zoomx]

I changed the Arduino nano.

Disable Alecto V1 plugin
Disable all but Alecto V1 plugin

Unfortunately same result BUT reset doesn't happen after printing 20;01;Xiron;ID=0C03;TEMP=00df;HUM=62;BAT=OK;

So I disabled also Alecto V4 and AlectoV1 and it doesn't reset.

[couin3]

So, problem is narrowed to both those plugins Alecto V1/V4 ?

[zoomx]

Yes, it seems that.

what is the function of display_Footer()? It is called after all printing, for example after display_BAT(battery) but it prints nothing

void display_Footer(void) { sprintf_P(dbuffer, PSTR("%S"), F(";\r\n")); strcat(pbuffer, dbuffer); }

this add only ";\r\n" at the end in pbuffer?

Because it happens just after printing results. display_Footer() is called at the end also in Xiron plugins and no reset happens.

[couin3]

You got it right. pbuffer should not be manipulated by plugins directly. Hence all the display_XXX funcs (there's a standardisation theme too).

Those kind of wild resets may be due to (p)buffer overrun, I've seen that before...

[zoomx]

Got reset after this 20;44;Auriol;ID=56;TEMP=0001;BAT=OK;

That seems a spurios signal decoded this way

[couin3]

Running latest v4.0 branch (Head) I can reproduce the issue with my own TX3 sensor (LaCrosse 046)

[couin3]

Found out that AVR is more restrictive with string size... I have some files to consider!

[couin3]

This issue should be solved. "v2.0" is now a stale branch.(and v3.0 soon will) Please use Master or V4.0 branches for now.

v4.0 beta (Head) tested OK with this settings :

• Arduino Nano
• RX plugins : 001, 004, 043, 046, 254
• TX plugins : 004
• PLUGIN_MAX 5
• PLUGIN_TX_MAX 1
