If you find the answer please post it. I am very interested in this as well.

Does Lilygo make anything that will receive 5G? I know espressif had announced a C5 chip that will do it but I have no idea when it will actually be available.

If not any suggestions?

Anyone know what the PIN # that I should use to read the voltage in an app is on the TTGO unit?

Is there anything special I have to do in order to use an external antenna that is connected to the ufl connector on the board?

I connected an external antenna and saw virtually no difference in the range.

Thanks

I have received more TTGO with cases and they program fine. Looks like I got a defective unit.

The T-3 has a ufl connector.

I connected an external antenna and saw virtually no difference in the range.

Is there something else I have to do to get an external antenna to do.

Case looks nice. Does it give you access to the 3 buttons on the S3?

I have several TTGO bare bones chips and can upload with no issues.

I just bought several of the TTGO with the case. On all of these the USB port is never seen so I cannot upload anything to them.

I am on a Mac (11.6.1, Big Sur) and have also installed the CH9102_Mac_Driver.

What am I missing here?

@teastain Thank you very much. That fixed my problem.

For some reason, Serial.print() does not send anything to the serial port.

I also tried the Hothead example. It has serial.print() statement but they don't do anything.

Any ideas?

I found the problem.

I forgot the S3 uses a different TFT_eSPI library.

Once I restored the old library things are working.

I had a project using TTGO and it worked.

I then had a project using the T3, I updated the Arduino settings and it worked.

I am now trying to go back to the TTGO, I set the board to ESP-32 Dev Module but the program just continuously resets.

I am sure there is something else I need to change in the settings b (probably around memory) but I can't get it to work.

My TTGO is 16 MB.

I have attached a screenshot of my settings.

Thanks

Just wondering if it is possible in the code to determine what kind of device (i.e., display size) is being used?

Also is it possible to get the NIC or unique serial number of the device?

If so, please post the code on how to do the above.

Thanks

I am really new to all of this and I think I have a simple question to answer. I am using the TTGO module.

Everything is working fine but I would like to have a larger display.

Is there anyway to connect a larger LCD display via the pins?

If not is there a different ESP32 board I should use and connect an external display?
