Hi, I have received the training model from Vtraining but ti does not work.
I am not even sure of what it should appear when the camera sees one of the objects i have trained. I have a good accuracy. Here is the boot.py I have, tell me what I can do to see if the camera is detecting something.

Thanks

Hi, is there any variable that identifies the device core2?
In that case, how could I get that identifier in UiFlow?
Thanks

Thank you @felmue I´ll try to use that.

hi again @felmue
Do you think there is any sense in using this in python "wifiCfg.wlan_sta.ifconfig()" setting the ip parametres inside the parenthesis?

hi @felmue
but that example only works for Arduino connection? I would like to do it in python.

Hi,

How can I set a static IP to the device when I connect it to a wifi network ?

Thanks.

Hi,
Is there any way to change the image of the screen that appears when you turn the device on?
It now shows a second of a uiflow logo and i would like to change it into my own logo. Any help?
Thank you!

Maybe there is a parmeter left in the code because I´ve tried to connect to the public server with the code and it happens the same

Hi @ajb2k3 @felmue
I have been working with the configuration you told me to connect with HiveMQ cloud with ssl. Now, using it I have seen an error. It does not subscribe to the topics a need to. See an easy example.

Here, when I press the button, the message "vamos" is send and it appears in the broker topic "hola" as it has to. But the button does not turn red. If I use the MQTT configuration block instead of the one that execute the code to connect it to a public server it all works properly, but I need to do the same in the private server with the ssl.
Thanks for your help.

Hi,
I am working with M%stack core2 and UiFlow and I am trying to work with the messages I receive from my MQTT server. From MQTT I receive a message like this {"itcrpc": "1.0", "user": "ITC-SCRIPT", "destination": "prueba", "method": "getStationStatus", "result": {'tag': 'Punto_A@00', 'type': 'STATION', 'status': {'sscc_occupation': None, 'occupation': True, 'dimensions': '1100;1250;1750', 'priority': 15, 'wait_replenish_pallet': False, 'replenish_pallet_type': 'euro', 'remove_pallet': False}}, "id": 1}.

And I would like to access to 'occupation' but in UiFlow I do not know how to do it. This is what I got. Thanks for the help!.

Hi again and I hope this is the last one.
Now I have discovered another thing. Due to the bug that skip 2 characters of the message you publish when you are working with Qos2 in UiFlow, if the message you are sending is less than 2 characters the server seems to do not even receive the message. So try to always send a message longer than 2 characters when you use the Qos2 in UiFlow.

Another thing M5Stack should fix is that you do not really send a QoS 2 message when you send it, it sends a QoS 1 as maximum.

Ok guys,
I have seen where is the problem. Last week messsages with QoS 2 did not work and I told to m5stack support team. Maybe they are now working on it as now if you put QoS 0 or Qos 1 it works with HiveMQ as always. I hope they fix that soon and we can work with Qos2.

@felmue Hi,
I used the new publishing method with Qos in UiFlow with HiveMQ last Friday and it worked perfectly I do not understand why today it does not work.

Hi,
Is there anyway to set a wifi password longer than 63 bytes in m5stack core2?
Thank you.

Hi,
I´m using the new MQTT function it has been included recently which allow you to change the Qos of the message you sent. There are 2 main problems, when you choose the Qos=2 it sends a Qos=1 message instead of 2. It also sends the message cleaning the first two characters of the message you are sending.
Anyone knows a solution?

@ajb2k3 oh... ok, thank you. I am asking the support team. Let´s see if they know something about it .

Hi,

I am working with M5stack core2 in UiFlow and I am trying to save messages in the EZ DATA function available on UiFlow. The problem is that after the first message it saves the device get stucked and stops working. Any solution?

Thanks

Is there any way to connect the M5 Stack core 2 device with a SQL server in UIFlow or Python?

Hi @felmue @ajb2k3

It finally works. Thank you so much guys for everything. Now I need to change the Qos of the messages I publish to 2, but I think UiFlow does not have that function implemented yet and will add in a future version.
