Hi, nice project. I am testing it on ESP8266/Nodemcu v3.
There is a problem. When it finds updates, it starts downloading them and…gives an error. It doesn’t download anything, but it deletes the old file. The other problem is that it “finds” an update without me putting the program.py file on the server. The error it gives is the same:

Completed 5 cycles, checking for updates
There is an update available
Download an update
Backtracking (last last call):
File “main.py”, line 63, in
File “urequests.py”, line 116, in get
File “urequests.py”, line 60, in request
OSError: [Errno 103] ECONNABORTED

The firmware is the latest version, but I tested it with another and the result is the same.
The only difference from the example given is that my server is on a local computer, not a Raspberry. I don’t think that matters in this case.

Regards,
Nikolay Alexandrov

Thank you for you regular messages you send out about IoT subjects.

Hello,
I’ve been reading your article about MicroPython OTA updates via PHP server.

https://randomnerdtutorials.com/esp32-esp8266-micropython-ota-updates/#more-109647

Can I ask if you have tried this technique with a Raspberry Pi Pico-W ??
Do you know if there is a fundamental reason why the technique couldn’t be applied to a Pico-W?

Kind regards, David (Dempster)

Hello
Do anyone have idea about OSError: [Errno 12] ENOMEM.
This occurs when esp32 sending the urequest to the php api.
Seems like it related to no sufficient memory according to my google.

Hello.
Do you have idea why it always say ‘unable to reach internet’.
I tried to send get request to the php by using browser, it’s working.
If I tried to print out the exception, using print(Exception), it is [Error no 12] ENOMEM.

Here is a link to some good info on securing PHP servers: https://docs.php.earth/security/intro/#use-https

Meant to reply to David before…

Thanks!

Main gives the error: ValueError: unknown config param (on line 42)

line 42: station.config(reconnects = 5)

This line seems to be the culprit. If I comment it out, the code works fine with all print statements firing when they should. Not sure if I really need the 5 reconnects.

You can have a file “doit.php”. In this file there are yours procedures to check the origin url, the mac address of the module, etc. to perform actions according to a code transmitted by $_GET. You can also add encryption of transmitted data.
