[solved] No data on dash board since update

[jmpratt]

I updated the firmware to 1.18.2.r0 and everything works fine but no data is displayed in the dashboard widgets. The Data page shows that all my signals are being received, just no graphs on the Dashboard. The Configuration page says my activation token has expired. Is that the cause?

Hi Jason, we're going to take a look at this. Can you "live updates" when you receive your signals on Data page?

Can you go to the Dashboard page, reload the browser, open your web browser console and send us a screenshot, please?

Expired activation token is standard behavior. This token is used only when a device is being added to Pybytes by firmware updater. Activation token expires after one hour.

@jirkakrepl I beg your pardon:

But i have similar issue: the data seems to be recived as is shown in the table, but the graphs is not displayed i send the screenshoot.


Thank you

Hi @nervencid, thank you for letting us know.

From the main table, it seems to me that data you receive from signal might be in the array.
How does your send_signal function look on your device? Are you sure you're sending float dataType from Python code, please?

@jirkakrepl Hello and thank you for your answer there is my code:

# Import what is necessary to create a thread
import _thread
from time import sleep

# Increment index used to scan each point from vector sensors_data
def inc(index, vector):
    if index < len(vector)-1:
        return index+1
    else:
        return 0

# Define your thread's behaviour, here it's a loop sending sensors data every 10 seconds
def send_env_data():
    idx = 0
    sensors_data = [0, -0.2, -0.5, -0.7, -0.8, -0.9, -0.9, -0.9, -0.8, -0.6, -0.4, -0.2, 0, 0.3, 0.5, 0.7, 0.8, 0.9, 0.9, 0.9, 0.8, 0.6, 0.4, 0.1]

    while (pybytes):
        pybytes.send_virtual_pin_value(False, 1, sensors_data[idx])
        idx = inc(idx, sensors_data)
        sleep(10)

# Start your thread
_thread.start_new_thread(send_env_data, ())

Hi, @nervencid

thank you for your code and reporting this issue. Please change your function send_virtual_pin_value to sendSignal. Documentation is also now updated: https://docs.pycom.io/pybytes/dashboard.html

here's the whole code:

# Import what is necessary to create a thread
import _thread
from time import sleep

# Increment index used to scan each point from vector sensors_data
def inc(index, vector):
    if index < len(vector)-1:
        return index+1
    else:
        return 0

# Define your thread's behaviour, here it's a loop sending sensors data every 10 seconds
def send_env_data():
    idx = 0
    sensors_data = [0, -0.2, -0.5, -0.7, -0.8, -0.9, -0.9, -0.9, -0.8, -0.6, -0.4, -0.2, 0, 0.3, 0.5, 0.7, 0.8, 0.9, 0.9, 0.9, 0.8, 0.6, 0.4, 0.1]

    while (pybytes):
        pybytes.send_signal(1, sensors_data[idx])
        idx = inc(idx, sensors_data)
        sleep(10)

# Start your thread
_thread.start_new_thread(send_env_data, ())

We broke send_virtual_pin_value function (we're going to fix it). It sends values, but they are inside one element array like [-0.8].

I created this screenshot to illustrate that. We're going to fix send_virtual_pin_value function. For now, use send_signal, please.

@jirkakrepl Hello again:

I rewritted the code and works fine thank you:

But you must specify that into:

pybytes.send_signal(1, sensors_data[idx])

where the "1" is for "Signal" parameter on pybytes and no the name

This the code that i used (the comments are in Spanish)

#ANTES DE TODO VERIFICAR QUE EL DISPOSITIVO ESTE AGREGADO A PYBYTES
#Importamos las librerias necesarias para crear un hilo
import _thread
from time import sleep

#Definimos una funcion que va recorriendo el vector continuamente
def inc(index, vector):
    if index < len(vector)-1:
        return index+1
    else:
        return 0

# Define your thread's behaviour, here it's a loop sending sensors data every 10 seconds
def send_env_data():
    #Indice inicial
    idx = 0
    #Datos sinteticos a enviar
    sensors_data = [0, -0.2, -0.5, -0.7, -0.8, -0.9, -0.9, -0.9, -0.8, -0.6, -0.4, -0.2, 0, 0.3, 0.5, 0.7, 0.8, 0.9, 0.9, 0.9, 0.8, 0.6, 0.4, 0.1]

    #Mientras estemos conectados a pybytes enviamos los datos
    while (pybytes):

        '''
        ENVIAMOS DATOS:

        El numero '1' corresponde a la etiqueta 'Signal' (y no 'Name') en la plataforma PYBYTES
        cuando es creada dicha 'Signal' verificar que coincida antes de enviar los datos
        '''
        
        pybytes.send_signal(1, sensors_data[idx])
        #Incrementamos o reiniciamos el indice para recorrer el arreglo
        idx = inc(idx, sensors_data)
        sleep(10)

# Iniciamos un nuevo hilo
_thread.start_new_thread(send_env_data, ())

@jirkakrepl Thanks for the response. I updated my code with the new command and it works fine.
