After a flash it automatically opens a monitor terminal for my serial debugging. I have temporarily solved the issue by specifying the exact monitor_port COMx value in platformio.ini. For example, the ESP32 board is on COM4, but the monitor_port wildcard is picking COM5. The good news is that this automatically launches the monitor terminal after each flash upload, but it chooses the wrong port for the monitor. I tried specifying the COM port with a wildcard in platformio.ino. But the serial monitor’s monitor_port does not auto-detect and instead I have to type in the COMx port. Platform is espressif32 V1.11.1, building on a lolin_d32_pro board.īoard flashing’s upload_port auto-detect is working correctly. You can quickly switch from the sniffer mode to the manual mode, repeat RS232 communications using our "Replay logs" plugin.I have Platformio IDE 1.10.0 installed on VSCode (WIN10). When studying serial communication protocols, you may want to repeat the same command sequence sent to serial equipment. How can our software help decode serial communication protocol? How can our serial software replace free Portmon?Īpart from Portmon, our software does not show low-level I/O requests but decodes them to a human-readable form. It didn't update for some time and may not work on modern versions of Windows.

Portmon monitors Windows kernel-level I/O packets sent/received between serial port device drivers. You can use the RS232 monitor without any programming skills. The RS232 monitoring tool does not require special knowledge, and students and professionals can use it to test/debug/view serial communication. The program allows you to store the settings for each copy individually. Start several instances of our COM port sniffer and monitor communication with your peripheral devices simultaneously. Using the serial port sniffer mode, you can monitor serial port activity without any cables and additional hardware.
