    • RE: I want to communicate data with M5stack Core2 and COM.Sigfox.

      @felmue Thank you.
      I tried your sample. I succeeded in compiling.
      But I can't write to core2 since yesterday.

      Displayed "A fatal error occurred: Failed to connect to ESP32: Timed out Waiting for packet header"

      Both of the Core2 I have are like that. Did my Core 2 break?
      I just wrote a sketch.

      Thank you.

    • RE: I want to communicate data with M5stack Core2 and COM.Sigfox.

      @felmue
      Thank you for suggestion Felix. And Sorry for my late reply.
      I tried Serial2.println("AT$SF=" + msg );.
      or Serial2.println("AT$SF= + msg ");.

      and Serial2.write("AT$SF= + msg ");.
      or Serial2.write("AT$SF=" + msg );.

      But I couldn't communicate.
      If you have new tips, I would love to try.

      Thank you.

    • I want to communicate data with M5stack Core2 and COM.Sigfox.

      Hello. I bought M5stack Core2 and COM.Sigfox. I want to use this for data communication.
      I was able to register the module in the sigfox backend. But I can't communicate or call back.
      When I use M5stack Basic and COM.Sigfox,I can do data communication and callbacks.
      Is there something wrong with my sketch?

      #include <M5Core2.h>
      
      void setup() {
       M5.begin(true, false, true);
       Serial2.begin(9600, SERIAL_8N1, 13, 14);
       Serial.begin(9600);
       }
      
      void loop() {
       int val = 11223344;
       String msg = String(val, HEX);
       Serial.print( msg);  Serial.println(" msg ");
       Serial2.print("AT$SF=" + msg);
       Serial.print("AT$SF=" + msg);  Serial.println(" AT$SF= msg ");
       delay(15*1000);
      }

    • How to use COM.X Sigfox with M5Stack and M5Core2

      Hello.
      I purchased M5stack Basic and Core2.
      I want to connect COM.X Sigfox to this and communicate with sigfox.
      So I installed the Arduino IDE, USB serial driver, board definitions and libraries on my PC. And
      I tried to write a sample sketch to get ID / PAC information to M5stack.

      M5stack Basic was successful.

      The following error message was displayed on M5stack Cors2.

      File "esptool.py", line 3682, in <module>

      Serial port COM3

      File "esptool.py", line 3675, in _main

      File "esptool.py", line 3329, in main

      File "esptool.py", line 263, in init

      File "site-packages \ serial \ __ init__.py", line 88, in serial_for_url

      File "site-packages \ serial \ serialwin32.py", line 62, in open

      serial.serialutil.SerialException: could not open port'COM3': WindowsError (2,'\ x8ew \ x92 \ xe8 \ x82 \ xb3 \ x82 \ xea \ x82 \ xbd \ x83t \ x83 @ \ x83C \ x83 \ x8b \ x82 \ xaa \ x8c \ xa9 \ x82 \ xc2 \ x82 \ xa9 \ x82 \ xe8 \ x82 \ xdc \ x82 \ xb9 \ x82 \ xf1 \ x81B')

      Failed to execute script esptool

      When Basic is connected to the PC, it is connected to com3 in Device Manager, but when Core2 is connected, it is com7. Something is wrong.

      What should I do? please tell me. Thank you.
