Using Soft AP

Q&A Forum › Category: ESP32 › Using Soft AP

David Huisman asked 3 years ago

Hi,
I see in the ESP32 and Micro Python courses you mention Soft AP mode but the examples are all showing the nodes in Station mode and require use of router.
Do you have example project using ESP32 with Software AP that enables mobile phone to connect to it without wifi network available? My app is simple, I have just want to be able to enter data on the phone and have the ESP32 transfer the data to my micro controller via ESP32 serial port and a message sent back as acknowledgement.

Hi David.
We have the tutorial that DK suggested to create a soft AP using MicroPython: https://randomnerdtutorials.com/micropython-esp32-esp8266-access-point-ap/

I followed the tutorial for burning the uPython firmware into the ESP32. (I am using ESP32 WROOM-U connected using TXD, RXD and Ground to PC via TTL Uart adaptor)
The program does the Erase ok to 100% then never starts the burn but comes up with com error.

I put module into pgm mode by pulling PGM pin LOW and then pull enable Low and High again

Hi David.
What ESP32 model are you using?
Are you using an ESP32 CAM?

I am using ESP32-WROOM-U.

I managed to get it programmed using the pytool utility.
Now it is programmed but never establishes the ap for some reason, just see the dots being printed while it tries. What can prevent the module from setting up the AP? It was working initially from Arduino code ok.

Did you solve your problem already? Or do you still have issues?
Can you share your code with us?
Do you have any peripherals connected?

I had to use ESP Flash tool and that worked. However, The device no longer creates an access point. It just prints the dots while waiting for establishment. What could cause that?

Hi David.
I have no idea why it doesn’t work if you say it was working before with Arduino IDE, but not with MicroPython?
Can you share your code with us?
With this information it is very difficult to find out what can be the problem.
