loaded stock code for esp lxdmxwifi example and in AP mode im getting hard reset and WDT error on reboot

Hello, I am trying to use the WiFi configuration tool with no luck.
I am running the java application in both Windows 10 and MacOs, however it is not working (no devices found).
This is on an ESP8266, not an ESP32.
If however, I try to use the python tool, I am getting an "exception reading packet" on the console log.
I have tried both in AP and Station mode. The wireless connection is working and the DMX changing (I am using "Art-net Controller" on Android)
Thank you for your time.

Hello,
This project is great for me, i want to delete dmx cable between midi foot module and light devices.
But I'm not sure to understand what I'm suppose to do... I have 4 lights with one d1 mini each and one d1 wemos to send dmx of the foot module.

• you say :"you configure one microcontroller to convert DMX to Art-Net in access point WiFi mode" :
  so I put this line :

  strncpy((char*)_wifi_config, CONFIG_PACKET_IDENT, 8); //add ident
  _wifi_config->version = DMXWIFI_CONFIG_VERSION;
  _wifi_config->wifi_mode = LX_AP_MODE;
  _wifi_config->protocol_flags = INPUT_TO_NETWORK_MODE | RDM_MODE;

and you say "Then, you configure another to convert Art-Net to DMX in WiFi station mode. The second Art-Net receiver should be connected to the WiFi SSID created by the first (AP/sending) microcontroller."

so I put this line on the second :
strncpy((char*)_wifi_config, CONFIG_PACKET_IDENT, 8); //add ident
_wifi_config->version = DMXWIFI_CONFIG_VERSION;
_wifi_config->wifi_mode = LX_STATION_MODE;
_wifi_config->protocol_flags = INPUT_TO_NETWORK_MODE | RDM_MODE;

how configure receivers as "converting Art-Net to DMX in WiFi station mode." ?

Could anybody help me please ?

Thanks a lot

Hi Claude,
I'm quietly new to ESP and programming. I was looking for some sketches to build an RGBW Led Light with DMX serial capabilities and after trying different projects I found yours. I had to say it was perfect and quite simple to understand and I really congratulate you!
After that... I was wondering if it could not be more easy to add a Wifi manger to set Wifi settings and Artnet or sACN type of transmission instead of configuration utility? It could be added also, for example, a power sequence to reset it instead of placing things on the hardware... Obviously I'll try by myself to do that but I think it could be added to make it easear to change setting in a simple way.
Thanks a lot!

When I compile to upload on adafruit feather I have error:
'class LX8266DMX' has no member named 'numberOfSlots'

Hi Claude,
sorry, I know, I'm a pain in the ass...
I'm trying "Osram DMX WiFi controller" App to drive my Led light with your library with ESP32. To work you should Poll the Artnet node. When connected to a local network (static mode) Artnet node is found and I can drive my light but in AP mode Artnet node is not found or found as 0.0.0.0 IP Address and I can't control the light.
Is this correct? There's a way to solve this?
I found that also with a PC software (Chamsys for PC) in AP mode the Artnet node found is 0.0.0.0
Knowing in advance my AP IP Address maybe I can set the Artnet node IP Address?

Hi,
I'm using this library with ESP32 and Fastled library. Everything work fine with at maximum 170 led and 1 universe:
for (int i = 0; i < NUM_LEDS; i++) {
leds[i] = CRGB(ESP32DMX.getSlot(i * 3 + 1), ESP32DMX.getSlot(i * 3 + 2), ESP32DMX.getSlot(i * 3 + 3));
}
FastLED.show();
There's a way to use Fastled with multiple universes, with more than 170 Led?

Thanks

Hi

Today I tried the code DMX2WiFi which I have chosen ArtNet protocol but it does not work for me as I have chosen the input signal from FTDI as (Entec Open DMX) do not know where could be the problem ? when you connect a DMX signal LED flashes quickly but on the other device nothing happens.

Hi,
Firts of all very nice project!

I try to use Unicast.

I noticed a problem with some programs. The IP address was not recognised correctly.

The software I use is Lightjams.
The IP address in the programm is recognised as 0.0.0.0 ; When I change it to the correct IP it works.
The problem is when a node disconnects and reconnect the IP is changed to 0.0.0.0 and the system stops working.

I analyzed the problem in DMX workshop and noticed the following:

Artnet Report node:

In the node status and output routing it works ok.

I suspect that the IP is not defined in the node report.
Can I fix this in some way?

hello i have a problem with esp32dmxrdm when i go in station mode

I just changed that in LXDMXWIFIConfig.cpp in line 76
_wifi_config->wifi_mode = STATION_MODE ; // AP_MODE or STATION_MODE
_wifi_config->protocol_flags = MULTICAST_MODE; // sACN multicast mode
// optional: | INPUT_TO_NETWORK_MODE specify ARTNET_MODE or SACN_MODE
// optional: | STATIC_MODE to use static not dhcp address for station
// eg. _wifi_config->protocol_flags = MULTICAST_MODE | INPUT_TO_NETWORK_MODE | SACN_MODE;
strncpy(_wifi_config->ssid, "RIRI-DMX-WiFi", 63);
strncpy(_wifi_config->pwd, "riridmxwifi", 63);

it connect this on another esp32 in ap mode with ssid and pwd, of course with esp32-dmx_rdm

Hi Claude,
I found this problem. Trying to control my light with Aurora DMX (App on Google store) my light start flashing instead of staying always on.
When i tried with other software same result. At the end I discovered that they both use the "Changes only" transmission type. It means that controller only outputs data on changes exept one per second (that's why my light flashes).
This is done to reduce the output data on heavily loaded network.
For better compatibility this could be corrected in the library? Or I have to write corrections needed on my firmware to not have my light flash?

This is kind of 2 issues, but they might be related. I have 2 identical ESP-12N development boards each with it's own MAX485 driver. I am trying to set up one as a transmitter and the other as a receiver. I am using the ESP-DMX example code. I am not using the configuration utility, but instead changing the values in DMXwifiConfig::initConfig. I can get the boards to talk to each other, however I cannot check any debug information on the transmitter.

The only differences between the 2 in code is the following lines.
Receiver:
_wifi_config->wifi_mode = STATION_MODE;
_wifi_config->protocol_flags = MULTICAST_MODE | STATIC_MODE;
Transmitter:
_wifi_config->wifi_mode = AP_MODE;
_wifi_config->protocol_flags = MULTICAST_MODE | INPUT_TO_NETWORK_MODE | SACN_MODE;

I have uploaded the same code onto both boards to check if it was a hardware issue, but it makes no difference. If the board has the flag INPUT_TO_NETWORK_MODE the serial monitor no longer works, just outputs garbage. I also ruled out AP_MODE, the following outputs correctly:
_wifi_config->wifi_mode = AP_MODE;
_wifi_config->protocol_flags = MULTICAST_MODE | STATIC_MODE;
But this does not work for transmitting over the network.

Despite the serial monitor not working, the code appears to be functioning correctly (or at least partially). The transmitter does set up an access point with the correct parameters, and the receiver connects to it instantly. It seems to be dropping frames though.

I am using qlcplus and a DIY OpenDMX USB device that is transmitting at 30 frames/sec. The ESP transmitter LED is blinking steadily when data is present. The receiver LED is completely sporadic, and the DMX data coming out of it is as well. Both units are running at 160 MHZ, and are located ~10cm apart. They are running off the same 2 amp 5v power supply. I have tested using both SACN_MODE and ARTNET_MODE and neither seem to work better. I have not tried unicast yet, and would prefer to stick with multi if possible.

Has a similar setup worked successfully for anyone else? Wondering if there's something that i am overlooking?

EDIT:
Suspecting the dropped frames were an issue with the AP_MODE, I set up a consumer router as an access point and ran both the transmitter and receiver in STATION_MODE. The transmission became much more stable, and is actually usable now. I suspect that there is some overhead in the softAP that is unable to handle DMX.

I still cannot use the serial monitor, but the system is functioning.

Hi

I tested your code and it works perfectly but I am wondering whether it is a configuration utility that acts like a https://github.com/media-architecture/NodeUtil it would be great if they could find multiple devices in a single network, I think it would be useful for a better view and configure devices on the network.

hello claude, i have some problem with esp32-dmx_rdm.
I would like to convert my entry dmx to artnet.
I do not understand : ligne 138 to LXDMXWIFIConfig.cpp
bool DMXwifiConfig::artnetMode(void) {
return ( ( _wifi_config->protocol_flags & SACN_MODE ) == 0 );
}
i tried to change it on:
return ( _wifi_config->protocol_flags & ARTNET_MODE ) ;

but it does not work. still no artnet on the network.

Hi!

First of all, thank you for making this great lib available!

I seems that there's an inconsistent function declaration since the last commit:
prototype for 'void DMXwifiConfig::readFromPersistentStore()' does not match any in class 'DMXwifiConfig'
in the NeoPixel example.

I think
uint8_t readFromPersistentStore(void);
should be
void readFromPersistentStore(void);

in examples/ESP-DMXNeoPixels/LXDMXWiFiConfig.h.

regards
Leonhard

I see that there are many projects, but it is not clear.
I'd like to send dmx siglal 20 meters.
Would be to do a DMX transmitter and one DMX receiver .
It is not clear to me if it adjusts in the projects?
greeting

Hi!
Thanks for making this library available! I tried the ESP-DMX example using an ESP8266 12F.
It does work, however the frame rate seems to be pretty low. Fades are not continuous and stuttering in my test setup. Is this a general limitation of the ESP8266 or is there something wrong with my setup?
Thanks!

Best, Leonhard

Could we get some better documentation? At minimum some better labels for what the examples actually are?

This library seems like it does exactly what I need but the documentation is a joke.

Hi

Please can you tell me how I could add another port to this library, therefore, that I would need to operate more than 512 channels thanks.

Hi!

Using the library today, I had to make changes to

Secondly, after investigating why my ArtNet packets weren't being received
I changed

It seems that INADDR_NONE is equal to -1, not 0.

but, I've previously used this library in late 2017/early 2018 and it worked.

Just wondering if you were aware of this, or it's some misconfiguration on my end

hello claude,
i followed your instructions.i managed to connect with esp-dmx configuration utility
I had to make a mistake because since I upload.impossible to reconnect to esp32 .I have therefore taken your example esp32-dmx-rdm and load in the sp.
but still nothing .esp-dmx configuration utility finds nothing.

I would like to assemble one transmitter and several receivers to transmit only DMX signal
is it possible to implement this on ESP-01S boards?

Hi

Can you please suggest how I define instance Universe - 1 and Subnet - 1, Because I am not entirely sure how can I do thanks.
