Hello everyone, does anyone know how I can connect my M5Stick V to my M5Stack Fire using serial communication? These are a part of the codes I use.

Stick-V

import time
from machine import UART
from fpioa_manager import fm

fm.register(35, fm.fpioa.UART2_TX, force=True)
fm.register(34, fm.fpioa.UART2_RX, force=True)
uart = UART(UART.UART2, 9600)

while(True):
uart.write("Hello World!\r")
time.sleep(1000)

Stack-Fire

#include <M5Stack.h> // needed for my board M5Stack

HardwareSerial m5stack_uart(2);

void setup()
{
M5.begin();

Serial.begin(9600); ;
m5stack_uart.begin(9600, SERIAL_8N1, 16, 17);
//Serial2_.flush();
Serial.println("Hola");
m5stack_uart.println("Hola");

}

void loop()
{
m5stack_uart.println("@");
if (m5stack_uart.available()) {
String s = m5stack_uart.readString();
Serial.println(s);
}

if (Serial.available()) {
String s = Serial.readString();
m5stack_uart.println(s);
}

}

Hello everyone, I have a problem with my M5StickV, reading the model (kmodel) from SD memory. The system returns the following error, when accessing the SD memory.

['flash']
['ding.wav', 'startup.jpg', 'freq.conf', 'boot.py']

Traceback (most recent call last):

Hello I recently bought a M5stick V and I'm trying to program it using the Maix Pi IDE. I have updated the device firmware, but I couldn't get it to connect. Someone knows how to do this, or there is another micro python programming IDE for this device.

Hello everybody, I have a problem, I'm trying to send a wav file using the "urequests" library, but I can't do it. I use a M5GO (FIRE) and micro-piton returns the following error:

TypeError: object with buffer protocol required

Any one knows how I can solve this?.

This is my code:

    url = "http://server_addres/wav_file"
    fin = wave.open('/sd/temp.wav', 'rb')
    
    file_to_send= {'file': ubinascii.b2a_base64(fin)}
    header={"content-type":"audio/wav", 'file': ubinascii.b2a_base64(fin)}
    
    # data=file_to_send,
    
    try:
        r = urequests.post(url,  headers=header)
        print (r.text)
    finally:
        print("Close...")
        fin.close()

Hi, I solved a similar problem by flashing the camera again. I downloaded the firmware located in: https://github.com/m5stack/esp32-cam-demo. To flash the camera I used this software https://www.espressif.com/sites/default/files/tools/flash_download_tools_v3.6.4.rar.

Once has been downloaded the tool it has 4 options, I used the option 3 and I configured the tool as show in the image:

I hope this helps you.
