Help with T-BEAM Install

I had bought this:
Followed this steps here:
So, plugged the device into my machine. I get a flashing blue light. I have the device drivers installed, but it never comes up in the “Ports” under device manager. Has anyone else had this issue?

Hopefully someone who uses windows can help, but yeah - the device should show up as a serial port.

Are there any settings I should click on the board itself? Or just literally plug it in?

I tried another one as well, same result.

hmm - I bet windows doesn’t have a driver for the serial chip in the tbeam.

Can you try installing this:

And report back?

All…was incredible bad luck on my end. I had tried TWO usb cables when I wrote that post.

I grabbed a PS4 controller USB cable and tried it…WORKS!

Moral of the story, make sure your USB cable works with data.



I use the ESPHome-Flasher-1.2.0-windows-x64.exe program to see which port it is on, and then connect via putty. I have 4 config files saved on putty that range from com1 to com4 as the com port number can change…

As well I look for the OnPassKey 6 digit number for the bluetooth pairing. One of my devices was, and is, very picking on providing the OnPassKey, and the other provides it. The two boards I have are the same, but work differently. Oh and the OnPassKey changes on one of the boards occasionally as well.

It takes some work but I can get both boards to work, and they each have a different personallty. I have to bring up the two boards up in a specific order, even though they are the same, and have the same software load.

They do work well when they are working and worth the effort.
