FTDI to USB cable: the selected serial port does not exist or your board is not connected

Development Tools IDE 1.x

Hello. I am trying to upload code using an FTDI to USB cable. The code is the OTA Web Uploader code that lets me utilize the ESP32-WROOM-32 wifi chip on the board that lets me upload code wirelessly. The FTDI cable is connected to the ftdi pins on my Fluxamasynth 32 module. For some reason, the Arduino IDE program is not recognizing the FTDI to USB cable i am using. My guess is that the cable is faulty, or I chose a wrong board that doesnt work with my cable:

I have no experience what-so-ever with ESP32 boards.

You have selected COM3 from the tools menu; does that port disappear from the tools menu when you remove the TTL-to-USB converter? If not, it's not your FTDI adapter.

If yes, you can try the loopback test by disconnecting the cable from the board and connecting RX and TX of the cable. That should give you the indication if the adapter is OK or not.

And that's how far I can help, I think.

Make sure that the ground wire of the FTDI cable, the black wire, is on pin 6 of the FTDI connector of the Fluxamasynth. The yellow wire is the RX which should line up with pin 2 and the orange wire is TX which should line up with pin 3. I think the supplied connector is configured how you want it just make sure the black wire goes to pin 6.
