no that is not the issue a 8bits board can talk to 32bits by serial without issue - esp32 is sensitive and ony work on gpio pins with 3.3v - are your rx /tx pins using 3.3v or 5v from your printer board ? |

Yes, I am aware of the 3.3V and 5V voltage issue with the RX and TX pins. Initially, I used a voltage divider to lower the voltage for the ESP32, but unfortunately, this didn't establish communication. To ensure voltage compatibility, I subsequently utilized a logic level converter, but the communication issue between the two devices persisted. |

you connect to which uart on your board ? the one used by USB also ? |

I connected to the same pins as instructed in the tutorial (https://esp3d.io/esp3d/v3.x/installation/wiring/index.html#creality-cr10-ender-3-board). The connection to the UART of the board is confirmed to be correct because, using my logic analyzer, I can observe the Marlin startup message. |

are you using same baud rate as Marlin ? |

I would the suggest to find a USB/Serial adapter like these : https://www.aliexpress.com/w/wholesale-ftdi-adapter.html If ok then do same with your esp32 and send [ESP420] or [ESP800] this will also allow you to be sure the pins are functionnal That would help to debug your issue |

Yes, I just tried using a USB/Serial module, but unfortunately, no data is coming from the printer's board. Interestingly, the ESP is responding perfectly. What's strange is that I'm not seeing anything in the serial console of the Arduino IDE, yet my logic analyzer detects the startup message from the Marlin firmware. I'm still in the process of testing various methods to send data to the printer and receive a response. However, this ongoing issue leads me to suspect that the problem might indeed stem from the board itself. As a next step, I'm considering purchasing a new board. |

Ok so if the issue is not actually linked to ESP3D , I think issue can be closed, that said if you found a solution on your board let us know, so we can add the method to : https://esp3d.io/esp3d/v3.x/installation/wiring/index.html |

Issue: Communication Problem Between ESP32 and Ender 3 (V1.1.4) (Bit Size Compatibility)
Description
I am encountering difficulties in establishing communication between an ESP32 module and my Ender 3 printer with a V1.1.4 board. I suspect that the issue might be related to the differences in working bit sizes – the Ender 3 operates on 8 bits, while the ESP32 is a 32-bit device. This GitHub issue is to seek help, insights, and solutions to address this bit size compatibility problem.
