Hi All, I'm trying to get FauxmoESP running on an ESP8266 with my Alexa and am having some troubles. The sample sketch compiles and appears to run alright (it connects to my home network) but when I try to discover via the Alexa app no new devices are found. Below is my configuration:

Alexa: Amazon Fire TV Cube (2nd Gen I think), connected to router via ethernet cable. Board: Adafruit Huzzah ESP8266 Breakout, connected to 2.4GHz WiFi Arduino IDE 1.8.13 (Windows Store 1.8.42.0) ESP8266 Core: 2.4.2 (also tried 2.7.4 with no luck) FauxmoESP V3.1.1 ESPAsyncTCP current as of 10/26/2020 lwIP variant set to "v1.4 Higher Bandwidth" For code, I started the sample fauxmoESP_Basic. I added #define DEBUG_FAUXMO Serial and removed 3/5 devices based on other peoples issues. Below is the serial output.

}

No resolution yet, but I wanted to note a couple findings.

In the example above, then the Echo requests a list of devices, the JSON string that is being returned is > 4000 bytes. When ESPAsyncTCP sends this (via lwIP), it gets split into a couple packets, as expected, however it is being truncated at the limit returned by tcp_sndbuf(_pcb), which in my case is a bit under 3000 bytes. The remaining ~1000 bytes is simply truncated.

Note that there might be more than one issue currently, and I'm just reporting on one that I have clearly identified.

@jenniferlee1818

I think I follow what you mean, and this could indeed be an issue. Good idea. I'll have a look and think about it and let you know shortly.

@pvint specifically how about a unique id that contains, rather than 000001, 000002, etc., a datetime with milliseconds. I think that would solve my problem. Not sure about others.

The way the code is structured that's not a trivial change (not really a big deal, but too big of a deal for this evening!)

If you want to give it a try, edit fauxmoESP.cpp and around line 127 you'll see:

    snprintf_P(
        buffer, sizeof(buffer),
        FAUXMO_DEVICE_JSON_TEMPLATE,
        device.name, mac.substring(6).c_str(), id, 
        device.state ? "true": "false",
        device.value
    );

Try changing line 127 to something like:

device.name, mac.substring(6).c_str(), id + 1000,

This is just as an experiment (sorry, I'm getting too tired to try myself now!), and it would be interesting to see if it gets around the issue you're having.

@pvint yes, thank you I'll try it.

I didn't find much time for testing during the week, but spend quite a while with this today. So far, it looks pretty promising. I was using the Master branch code without any change. This is on ESP8266/NodeMCU v0.9 and with Echo Dot 2G. Discovery seems to work stable. The only issue I came across is that one about old devices that appeared again. I narrowed it down to some extent: In the past, I did a "Remove all" in the Alexa app, but it seems that this was the issue. When I remove all, they come back with discovery (but with old names, instead of new ones). Now if I just remove selected ones (e.g. my device ID 2 and 5 because I gave them new names) and do discovery again, then it seems to work perfectly fine. I was able to discover and control 8 devices using fauxmoESP

@pvint the discoveryIssue works for me, and found old devices names too; No problem to delete them, thanks!

Appreciate the feedback everyone. Also please note that the discoverIssue branch has been merged to master.

I just ran into this issue as well. The Alexa app won't recognize my device. (I don't own any Echo hardware to try)

So, I updated the firmware to that from 15 days ago: https://github.com/vintlabs/fauxmoESP/issues/126 (doesn't fix it)

Then I tried the suggested code change: https://github.com/vintlabs/fauxmoESP/issues/120#issuecomment-725668624 (doesn't fix it)

I added #define DEBUG_FAUXMO_VERBOSE_TCP true but still only get the below output:

[WIFI] Connecting to Pik_Mob .....
[WIFI] STATION Mode, SSID: Pik_Mob, IP address: 192.168.10.139
[MAIN] Free heap: 247684 bytes

I'm available to test any code fixes.

I can confirm the same as @societyofrobots. Yesterday I switched everything off. i.e. router, access points all ESP fauxmo devices and Alexa hardware devices and then switched them all back on. All of a sudden the discovery started working again. Today discovery is not working again. I am currently experimenting with 2 ESP devices and changing the names of the fauxmo devices i.e. fauxmo.addDevice("tester 1") then changing to fauxmo.addDevice("tester 2"); and re-sending to device. Not sure what is going on exactly, but happy to try things out. I am currently using the latest committed code.

Delete your old devices via the Alexa App (I found the Web version alexa.amazon.com worked the best) and try discover again.

I removed all fauxmo devices using alexa.amazon.com (thanks for mentioning that btw as it is much easier than asking alexa all the time 👍 ). I also removed a sonos device as a test to see if discovery re-found it. The result of web triggered 'discover devices' was that the sonos was found again, but zero fauxmo devices were found. I rebooted the fauxmo devices and tried discovery again and still no joy.

Update: Just tried again and eveything has been discovered including old device names which are no longer in any fauxmo code I have. All I did was to restart 'discover devices' via alexa.amazon.com and then 10 seconds in I restarted one of the fauxmo ESP devices. Strange behaviour, some kind of caching perhaps in local router or echo devices? Anyhow, I can now get back to project. Still happy to try out any suggestions, as I dont think I have seen the last of this issue.

Update: The discovery is still temperamental. I have also noticed a few duplicates being found. For example I have defined 8 devices on one ESP8266 using Fauxmo and I have ended up with 10 in the Alexa app (2 duplicates). I wonder if the unique ID/naming is somehow registering duplicates on a restart or during a re-discovery pass? Will continue to post any findings.

@pvint What version should we be testing with? I started seeing issues with Discovery again this evening.

If I were to offer a bounty to have this issue resolved asap, would any developer be interested in tackling this?

Ideally I'd like to use this software for a lock, and the user would be requested for their pin.

I am now getting stack dumps when I ask Alexa to discover devices. ESP8266 D1 Mini R1

The sketch I used to generate this stack was working fine with introduction of the 3.1.2-RC1 version, until last night. I started seeing these stack dumps while working on making modifications.

The stack dumps only start after I asked Alexa to discover new devices. The first dump occurs close to the end of Alexa's discovery cycle. At that point the ESP reboots continuously after the first stank dump. The dumps stop immediately when I unplug the Alexa Echo.

If I leave the Echo alone, don't unplug it. but instead I unplug the ESP so I can read serial monitor. When I plug the ESP in again the stack dumps start almost immediately and the ESP continues to reboot. ??Alexa running a muck??

I've been able to reproduce an issue this morning. It's not happening every time, but I feel like there's an order of operations that could make it reproducible every time.

Here's two different failure modes I have had this morning:

Both of them seem to be after the Echo device does repeated requests to GET /api/2WLEDHardQrI3WHYTHoMcXHgEspsM8ZZRpSKtBQr/lights HTTP/1.1

Still looking, but it looks like something is writing to invalid memory at or before client->onDisconnect([this

Since adding a bunch of debug statements (and subsequently removing them), I am no longer able to reproduce the issue on any of 4 different ESP8266 boards and with Gen2 and Gen3 Echo devices.

I'll try again a bit later, but if anyone can let me know how they are getting it to crash please let me know!

I'm not getting normal Exception # dumps. But I am getting 2 different dumps. The first dump right after Alexa Discovery and a different dump after ESP reboots.

First Stack Dump:


User exception (panic/abort/assert)

Interesting. I'm still completely unable to get a crash.

@ddweber456 - Can you try the following please:

Use this minimal sketch (along with a credentials.h like the examples)


#include <Arduino.h>
#ifdef ESP32
#include <WiFi.h>
#else
#include <ESP8266WiFi.h>
#endif

include "fauxmoESP.h"

// Rename the credentials.sample.h file to credentials.h and // edit it according to your router configuration

include "credentials.h"

fauxmoESP fauxmo;

define SERIAL_BAUDRATE 115200

define DEVICE_NAME "Aardvark"

// ----------------------------------------------------------------------------- // Wifi // -----------------------------------------------------------------------------

void wifiSetup() {

// Set WIFI module to STA mode
WiFi.mode(WIFI_STA);

// Connect
Serial.printf("[WIFI] Connecting to %s ", WIFI_SSID);
WiFi.begin(WIFI_SSID, WIFI_PASS);

// Wait
while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(100);
}
Serial.println();

// Connected!
Serial.printf("[WIFI] STATION Mode, SSID: %s, IP address: %s\n", WiFi.SSID().c_str(), WiFi.localIP().toString().c_str());

}

void setup() {

// Init serial port and clean garbage
Serial.begin(SERIAL_BAUDRATE);
Serial.println();
Serial.println();

// Wifi
wifiSetup();

fauxmo.createServer(true); // not needed, this is the default value
fauxmo.setPort(80); // This is required for gen3 devices

fauxmo.enable(true);

fauxmo.addDevice(DEVICE_NAME);

}

void loop() {

// fauxmoESP uses an async TCP server but a sync UDP server
// Therefore, we have to manually poll for UDP packets
fauxmo.handle();

}


Edit `libraries/ESPAsyncTCP/src/DebugPrintMacros.h` and uncomment the following lines:
```C
#define DEBUG_ESP_ASYNC_TCP 1
#define DEBUG_ESP_TCP_SSL 1
#define DEBUG_ESP_PORT Serial

Then post the serial output along with the backtrace.

Thanks!

Interesting note: I just reconnected the ESP and it immediately after reboot started giving the stack dumps. I didn't capture the dumps but I'm sure I can reproduce it it helpful. When I unplugged the ECHO the dumps stopped.

When I unplugged the ECHO the dumps stopped.

Very strange, and interesting.

Also interesting that although the two crashes look different, they both are occurring right after [ASYNC_TCP] _recv[2]: 130, PBUF_FLAG_PUSH

I'll do some digging.

Thanks David

I'm a bit stumped right now - can you set, in fauxmoESP.h:

#define DEBUG_FAUXMO                Serial
#define DEBUG_FAUXMO_VERBOSE_TCP    true
#define DEBUG_FAUXMO_VERBOSE_UDP    true

and reproduce the crash again?

If You like, You can use this library in attached.. that works for me.

I can't get the esp32 discovered by alexa app. I am trying with fauxmoESP_Basic.

Is there any secret to make it work ?

If You like, You can use this library in attached.. that works for me.

@adbensi The library you spoke of was not attached. If you have something workiing right now, I sure some people would be interested. thanks

Same here. Discover of esp32 did not work. Please share some working tipps with us 👍

I am not currently able to reproduce a fault using either ESP32 nor ESP8266.

If you're still having issues, please be sure to test with the latest master branch in git or the release 3.1.2-RC1. (The libraries in Arduino and PlatformIO are both out of date and I am working on getting them updated).

@ddweber456 : For your particular case, one thing that I have noticed is that it looks like you have a few devices broadcasting on SSDP (Example: SERVER: Linux/4.4.120 UPnP/1.0 Cling/2.0). Would you be able to quiet them down for a test? Obviously, if that is somehow causing an issue that needs to be addressed, but it might be some more info.

I don't have a Linux server. I'm not a network guy, but isn't this packet normal SSDP, universal plug and play traffic? I see several HOST: 239.255.255.250:1900 generated packets from various SERVER: from time to time.

I have removed all other ESPs from my LAN and I still can't get Alexa to discover. I will be happy to continue generating logs and stack dumps, whatever you need, when your ready for them. (I can't test the hard reset issue until Alexa starts doing discoveries correctly, I just don't have that knowledge base) thanks

Linux Kernel 4.4.120 is quite old and speaks for a router or nas

@ddweber456 That's cool - offhand I don't know what it is either, but like @thosoo says, it sounds like a router or something. No biggie, just thought it was worth a shot to fish for more info. Appreciate the help (and the offer for more!)

I'll dig back into this in the morning.

Thx @pvint , I'll try master branch today. My issue was I used latest platformio lib... Hope my issues are solved by using master instead. I'll report later today 👍

This packet might also be a FireTV stick. The example there looks quite the same. https://developer.amazon.com/docs/fire-tv/dial-integration.html

Good find! Yes, I do have a couple fireTV sticks.

Update: 12-9-20 16:40GMT Thinking that the FireTV stick maybe a contributing factor to the discovery issue I turned off ALL Alexa controlling devices, FireTV, Echo Show, Fire Tablet.... Only device left running is the Echo Dot Gen 2. Stack dumps and reboots are still occuring with "User exception 'Abort called' stack dump" for the first dump and a "User exception 'Panic umm_malloc.cpp:458 umm_malloc_core' stack dump at PBUF_FLAG_PUSH and subsequent reboot. I'm sure I reproduce the stack dumps, just ask.

Do I need an echo dot to have my esp discovered ?

I have tried everything that was suggested here but with no success on getting my esp discovered with the Alexa app.

@pvint I may be WAY off base with this, but I noticed the following release notes for the Alexa Voice Service (AVS) Devise SDK https://developer.amazon.com/en-US/docs/alexa/avs-device-sdk/overview.html I don't know if or how Fauzmo and Philips Hue interact with this SDK, but these the release dates look very suspicious to me. I started having discovery issues in June. Just a thought? maybe not?

@ddweber456 That is interesting. We don't actually use the SDK, we're just emulating Philips Hue, but no doubt there is a connection in the version updates. (also, I found it interesting that there was an update yesterday - I actually saw one of my Dots doing something last night while I was on a call)

Could you do me a favour, David? Would you mind creating a new issue for the problem that you're having? It seems like a very specific case, and I think it would be better to deal with it separately.

I take it you are still able to discover new devices OK?

Yes, I just did a fresh test with both an ESP32 and an ESP8266, and both worked fine.

@kbssa I just did it with my Alexa app on my android and it worked fine (I should disconnect all of my Echo devices and test again to be sure though)

Before I open a new issue, let me know if you see anything wrong with the library versions I'm using. Sketch you gave the the other day.

I have been using IwIP "v2 Higher Bandwidth", I switch to "v2 Lower Memory" No Success! Switch to IwIP "v1.4 Higher Bandwidth" Discovery SUCCESS! I'll do some more testing with different Echo Dots and the App and different sketches and post an update.

Update:: I was able to discover devices with Dot Gen2, Dot Gen3 and the Alexa app (screen add device only).
It appears to be as expected.

I'm assuming the use of IwIP v1.4 vs v2 depends on the flash memory chip? Maybe I just have an older version flash chip.

Good news!

Interestingly, I always needed "Higher Bandwidth" before (never seemed to matter if it was 1.4 or v2) - I must have been experimenting with something and set it to "lower memory".

@pvint any news about needing of having an echo dot for get the esp discovered by Alexa app ?
