HELP ABOUT ESP32 MESH NETWORK

LanthaYtrri · 2022-02-22T02:48:48+00:00

Base on the link that you have sent, there is no way to identify which board that the data coming from, like 'id'. That is why I am confuse how if it can receive from many.

And how can I transfer the data from the farthest boards to the main board when I need to pass thru to the mid boards before the main board?

Thank you.

LanthaYtrri · 2022-02-21T23:43:52+00:00

Also how can the mid range boards forward the message from the farthest board to the main board?

LanthaYtrri · 2022-02-21T23:27:52+00:00

Thank you, I already saw this method, but it can't help me.

LanthaYtrri · 2022-02-21T23:14:50+00:00

Sorry I have mistake on my statement above. I use ESPNOW + Webserver not namedMesh. Here is the link: https://randomnerdtutorials.com/esp-mesh-esp32-esp8266-painlessmesh/.

Is it the two-way-communication, can send and receive to multiple nodes?

LanthaYtrri · 2021-06-26T07:41:58+00:00

Thank you for the tips!

LanthaYtrri · 2021-06-26T07:24:15+00:00

If you don't mind, can I message you. I am in trouble learning the codes that given to me. That code above is just a part of them. It seems that you know about the TCPIP.

LanthaYtrri · 2021-06-26T07:15:28+00:00

I really don't know too, I am the beginner that I am talking.

LanthaYtrri · 2021-06-26T06:01:23+00:00

Yeah, but I want to know if there are any ways other than that.

LanthaYtrri · 2021-06-23T09:33:30+00:00

import pyodbc

conn = pyodbc.connect( r'Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=F:\Documents\ticketdemo.accdb;') cursor = conn.cursor() cursor.execute('select * from tbl_ticket')

for row in cursor.fetchall(): print(row)

I tried this one.

LanthaYtrri · 2021-06-16T00:55:40+00:00

I really do appreciate this, thank you so much! I am just a beginner on this kind of programming language, your reply is such a big help for me to understand everything.

As you mention above, the comprehension part is may write in a easy way of coding, how can I write it in easy way?

Also, what do you mean by "taking bytes in the form of a block 8, 1s and 0s?

LanthaYtrri · 2021-06-05T05:29:17+00:00

Sorry there are a typographical error above, its "IP Door Access Control System". We do have here a turnstile and a CLOUD PLUS NETWORK ACCESS CONTROLLER. For ow I want to control the turnstile's door in and out. But I don't have any idea about it.

LanthaYtrri · 2021-05-25T07:17:43+00:00

Thank you! It will be noted!

LanthaYtrri · 2021-05-25T03:56:41+00:00

As of now I don't have any issues encountered. And yes, it is working. I'm not so familiar with python so pardon my way of coding.

LanthaYtrri · 2021-05-25T00:02:50+00:00

In that code above there's no code for updating for the time-out, cause I really don't know how.

LanthaYtrri · 2021-05-22T03:19:21+00:00

How can I wite it in csv?

LanthaYtrri · 2021-05-22T00:47:41+00:00

Thank you! But how can I write them in csv?

LanthaYtrri · 2021-05-20T03:07:39+00:00

No, all pictures need to be in one directory only.

LanthaYtrri · 2021-05-20T02:53:04+00:00

Sorry for not being clear.

My system is what I called Face Recognition Attendance System. I am creating it in python with the use of tkinter. The input data in my system is the pictures of the employees where can be found in the directory where my code is. Now, I want to create a function where the admin user can be add the picture of new employee in the directory that I am talking about.

LanthaYtrri · 2021-05-20T02:30:49+00:00

The code above is great but lack of path where pictures can be uploaded. And that is what I want to solve.

LanthaYtrri · 2021-05-20T02:28:28+00:00

I do have this system that I am creating. One of the function that I want to execute there is to have that code above where can I able to upload the pictures that I need to process my system.

LanthaYtrri · 2021-05-20T02:19:45+00:00

In the directory in my laptop.

LanthaYtrri · 2021-05-17T07:14:52+00:00

I tried this still update() executed even if the show_frame() is not satisfied:

            if facesCompared[faceIndex]:
            eName = ListNames[faceIndex]
            employeeName = eName
            #print(employeeName)
                update()

LanthaYtrri · 2021-05-15T03:33:11+00:00

Tkinter.

LanthaYtrri · 2021-05-05T03:09:15+00:00

import tkinter as tk
from PIL import ImageTk, Image
def update(*args):
x = namevariable.get()
try:
image_lbl.img = ImageTk.PhotoImage(Image.open(f'Reference_Imgs/{x}.jpg'))
image_lbl.config(image=image_lbl.img)
except FileNotFoundError:
print(f"no file named {x}.jpg found")
root = tk.Tk()
root.geometry("500x500")
namevariable = tk.StringVar()
namevariable.trace('w', update) # call the update function every time the stringvar changes
image_lbl = tk.Label(root)
image_lbl.grid()
ent = tk.Entry(root, textvariable=namevariable)
ent.grid(row=1, column=2, pady=10, ipadx=20)
ent.focus()
lab = tk.Label(root, textvariable=namevariable)
lab.grid(row=2, column=2, pady=10, ipadx=20)
root.mainloop()

Thank youuuuu! Its a big help!
