AT firmware 2.4.0 on ESP32-C3 - Frequent WiFi disconnections

Open jaygitdev opened this issue 2 years ago • 2 comments

I am using an ESP32-C3 DevkitM-1 with AT FW version 2.4.0 and I'm having frequent dropped connections when transferring data. Below are the AT Commands I'm sending:

AT+CWMODE=2      // STA Mode
AT+CWSAP="esp32test","Aaaaa11111",5,3   // login, pw, channel 5, 3 max connections
AT+CIPMUX=1  //
AT+CIPSERVER=1,443,"SSL"  // SSL connection on socket 443

I'll then connect to the webserver, login to 192.168.4.1 in my browser and, it will confirm a connection is made.

I'll then send it:

AT+CIPSEND=0,321 // Send 321 chars

I'll receive a ">" and then send it:

HTTP/1.1 200 OK
Content-Type: text/html
Connection: close

<!DOCTYPE HTML>
<form method="post" enctype="multipart/form-data">
 <div>
   <label for="file">Choose file to upload</label>
   <input type="file" id="file" name="file" multiple>
 </div>
 <div>
   <button>Submit</button>
 </div>
</form>
</html>

This effectively will send it a navigation box and an upload button for me to stream data from a phone (or other device) to the ESP32 for display over the UART.

I sent it a 10 MB file and it loses connection while sending the file and essentially stops transferring data (though it will occasionally pick back up again and then stop again). I've tried it with multiple baud rates (921600, 115200, 57600) and the issue still persists. I've tried it in mode 1 and 3 as well with no luck. I've used the same AT commands on the ESP32-S2 Saola-1 and the issue does not seem to be present. This seems to point to an issue with either the hardware or the firmware.

I've tried this on multiple units, even ordered a new batch to try it on a different batch and the issue is reproducible. With future support going from the S2 to the C3, this is very concerning as the latest firmware seems to be unable to keep a stable connection.

Any suggestions/insight would be greatly appreciated!

@jaygitdev could you please enable debug log and ssl logs to see what happened.

  • ./build.py menuconfig -> Compent config -> Log output -> Default log verbosity -> Verbose
  • ./build.py menuconfig -> Compent config -> mbedTLS -> Enable mbedTLS debugging -> Set mbedTLS debugging level -> Verbose

I apologize for the late response, I didn't see this come in.

In the past, I have just used the binaries so my system wasn't previously setup for this. I was setting up my system and ran into some issues and I'm not sure how to resolve them prior to testing the suggestions you provided.

I went to [https://docs.espressif.com/projects/esp-at/en/release-v2.4.0.0/esp32c3/Compile_and_Develop/How_to_clone_project_and_compile_it.html# ] to follow the steps there. I started by installing esp-idf and successfully ran the hello_world example as suggested.

I then tried to install the dependencies for esp-at while using build.py and got the following:

At this point, I'm not really sure what to do or how to install esp-at to be able to setup the build command as you suggested.

I realize this is a different problem than the original problem, but I'll need to resolve this issue before I can setup the project as you suggested (unless you're able to either provide binaries for me to test or run the initial described problem with the 2.4.0 binaries from the ESP32-AT page). Ideally, I'd like to get this working so I can test this moving forward.

Any help you can give me would be appreciated. Thanks!
