PicoW [Errno 113] ECONNABORTED <class 'OSError'>

CircuitPython version and board name

Adafruit Circuit Python 9.2.8 dated 07/02/2025 on PicoW

Code/REPL

I have a wireshark dump I can upload to a private location if you would like. I'm pretty sure the issue is in the network stack, and not the code.

Behavior

[07/02/2025 21:18:22] ERROR InfluxWriter._send_request(body=tempmon,sensor=otext temp=68.30) Exception: [Errno 113] ECONNABORTED <class 'OSError'>

Description

So I have a device that I'm using. It has a LCD display, and a TMP102 thermometer.

It continuously polls the thermometer and once per minute makes an HTTPS POST request to place the data on a server.

I frequently get:

[Errno 113] ECONNABORTED <class 'OSError'>
[Errno 113] ECONNABORTED <class 'OSError'> socket_resolve_host() returned -2
[Errno 104] ECONNRESET <class 'OSError'>

For example, 20:12:39 failed, 20:13,and 20:14 succeeded, and 20:15:40 failed.

This was happening with 9.2.6 as well. Also, the issue happens in two different environments with quite different AP's, networks, etc.

I don't have the error message, but at one point I had a crash message where the kernel itself crashed, and the pico was locked up.

I have another one running an ancient micropython version, and it just works. Is there any hope for this ever working?

Additional information

When it starts failing, I see a lot of SYN, SYN/ACK retransmits between the two hosts. I'm also seeing ARP requests for the Pico's address from the router, but there aren't any corresponding replies.

I can provide you with the tcpdump capture file if you would like. It has both successful, and failing connection cycles.

Could you try 10.0.0-alpha.7? Also make sure all the CircuitPython libraries are up to date.

A wireshark trace may be helpful, but a small test program that we can run to reproduce the may be the most helpful. Are you talking to the same server in both network environments? Is it a local server?

We use the same library to talk to the CYW43 co-processor that MicroPython uses. In fact, it was developed by them: https://github.com/georgerobotics/cyw43-driver. We may be ahead or behind of the library version compared with your MicroPython instance. Maybe check the open and closed issues there to see if anything sounds similar to your problem.

My apologies. I went through and updated all of the libraries, try 10 alpha 7, and it seems to be working as expected now.
