Unexpected command: 41

[iker190]

I'm getting "Unexpected command: 41" error each time I start my program, sometimes the program starts correctly but it stops after a few hours (~2h). After that if I try to start the program again I get the error. I also get the same error when I try the readme example. I tried on a linux desktop computer and on a raspberry pi. I can see that command 41 is not implemented yet but I haven't seen anyone with my same issue. Could be a problem with my home network? What does the 41 command do? Thank you

Which hardware/os do you have? Please also provide your script code.

Hi, I'm using a raspberry pi 3 running Raspbian 9 stretch and Python 3.5.3. Here is my code:

import serial
import yaml
import BlynkLib
from time import sleep

MENU = [[1], [2, 3], [4], [5], [2], [3], [1, 2, 3, 4, 5]]
BLYNK_AUTH = 'my token'
serial = serial.Serial("/dev/ttyACM0", 9600, timeout=1)
blynk = BlynkLib.Blynk(BLYNK_AUTH)

def read_config_file(conf=2):
    with open("config.yaml", "r") as codes_file:
        config = yaml.load(codes_file)
        if conf == 2:
            return config
        if conf == 1:
            return config["configuration"]
        if conf == 0:
            return config["persianas"]

def send_command(cmd):
    if not lock:
        for blind in current_blind:
            command = blind_config[blind-1][cmd]
            print(command)
            serial.write(command.encode())
            sleep(0.1)
            serial.write(command.encode())
            sleep(0.5)

@blynk.VIRTUAL_WRITE(0)
def lock_handler(status):
    global lock 
    lock = int(status[0])

@blynk.VIRTUAL_WRITE(1)
def blind_handler1(sel):
    blind_read_handler1()
    sel = int(sel[0])
    global current_blind
    current_blind = []
    for i in range(len(MENU[sel-1])):
        current_blind.append(MENU[sel-1][i])

@blynk.VIRTUAL_WRITE(3)
def blind_handler2(sel):
    blind_read_handler2()
    sel = int(sel[0])+4
    global current_blind
    current_blind = []
    for i in range(len(MENU[sel-1])):
        current_blind.append(MENU[sel-1][i])

@blynk.VIRTUAL_READ(3)
def blind_read_handler2():
    blynk.virtual_write(1, 0)

@blynk.VIRTUAL_READ(1)
def blind_read_handler1():
    blynk.virtual_write(3, 0)

@blynk.VIRTUAL_WRITE(2)
def command_handler(cmd):
    cmd = int(cmd[0])
    if cmd == 1:
        send_command("up")
    if cmd == 2:
        send_command("down")
    if cmd == 3:
        send_command("stop")

full_config = read_config_file()
blind_config = full_config["persianas"]
setting_config = full_config["configuration"]
current_blind = []
lock = 1

while True:
    blynk.run()

It's been working now for a week without any error. The program remains unchanged.

I am facing the same issue and not solved. I am using NodeMCU ESP8266 and micropython. I get the error Unexpected command: 41 when using blynk: Below is my code ....

import BlynkLib import network import machine

WIFI_SSID = 'HamzaJraiwi' WIFI_PASS = ''

BLYNK_AUTH = ''

print("Connecting to WiFi...") wifi = network.WLAN(network.STA_IF) wifi.active(True) wifi.connect(WIFI_SSID, WIFI_PASS) while not wifi.isconnected(): pass

print('IP:', wifi.ifconfig()[0])

print("Connecting to Blynk...") blynk = BlynkLib.Blynk(BLYNK_AUTH)

@blynk.on("connected") def blynk_connected(ping): print('Blynk ready. Ping:', ping, 'ms')

def runLoop(): while True: blynk.run() machine.idle()

Run blynk in the main thread: runLoop()
