Can't Find WiFi after uploading the Code

[Reel18]

Hi, Please Help.
I'd like to ask about the wifi of ESP32 missing after uploading the original ESP32RET code (I can't find the WiFi on my laptop)
The Board I'm successfully uploading the code with no error was:

1. ESP32 Wroom32
2. LilyGo T-Display (ESP32 Wroom32 also)

and I failed to upload the code to ESP32 S3 to try out more, there's was an error
(error: 'class HardwareSerial' has no member named 'setTxTimeoutMs'; did you mean 'setRxTimeout'?)

after finish uploading, from the instructions I should see the WiFi from my Network, connect to it and I choose connection over WiFi on SavvyCAN.
.

From the videos I saw on YouTube. After the Wi-Fi is connected, the network connection IP should be filled automatically (http://192.168.4.1/).

is there something from with my procedure or anything else?

You will need to make sure that it is actually set to create the wifi AP like you are expecting. You can use the Arduino IDE's serial monitor to check this. Connect to the serial port at 1 megabaud (1000000) which should be an option in the list of speeds. Then send a ? followed by a line ending (CR, LF, CR/LF) and you should get a menu. From there you can see what sort of wifi it is attempting. Maybe it is trying to connect to an AP instead of making one. You can set it however you'd like by sending commands (such as PASSWORD=secretpassword!)

The S3 is supported but it's a different chip so you need to actually select an S3 chip from the boards manager in the IDE. This compiles it differently so it supports that chip.
