I found the problem.
The CH340 chip, which the D1 card uses, had a problem with the 5.5 kernel module that now uses the CH341.
I upgraded my kernel to 5.6 and even using the CH341 module, communication has improved.

Re: Strange characters with picocom
Trying to solve the problem, I installed Ubuntu on a Virtual Machine inside my Arch Linux.
And to my surprise, in Ubuntu, in a Terminal, I ran Picocom, and it worked without problems.
So I think it's not a hardware problem, it could be something with Arch's USB driver.
What can it be then?

Strange characters with picocom
Hi! I need help with a problem. I am using a D1 R32 board, it is the one that has the shape identical to an Arduino UNO. I work on Arch Linux, and use Picocom to receive the results of the serial output. Everything was fine, until the exit became unreadable with strange characters. W (6�) cpu_start:...

Help with BTree
Hello I am implementing a database with BTREE on ESP32. I read and reread the documentation and still remained many doubts. I saw that BTREE is very limited. But if anyone has an example could indicate me. I need to know how many records are in the database, and how to delete records per record. Is ...

Re: OTA of micropython code on ESP32?
Thanks, I saw this post.
However this is not what I am looking for, because there are file updates, downloading on github, also making an esp32 be an FTP server.
But what I only want is my ESP32 to download files from an FTP server on the internet, that's all.
That simple.
Does anyone have an example?

Re: OTA of micropython code on ESP32?
Hi!
Would you have any code that would download files from an FTP server?
I've been studying this for a long time and I can't move forward.
Thank

OTA simple concepts.
Hi! I searched the forum and elsewhere for OTA documentation for both firmware and code updates, but I didn't find anything that would make me understand how it works. I have never used OTA, so it seems unintelligible to me. Can someone tell me about OTA documentation, or explain to me simply how it...

Re: Store data temporarily.
Thank you for your attention. Helped me a lot. Power is not important as it has the device turned on with vehicle power all the time. So I will start to use the list, because I will have several data, ie several columns for each row, and this will be the best option. It had not occurred to me to sto...

Store data temporarily.
Hello people! I would like you to help me decide which way to use to store temporary data on an ESP32. I will be collecting the GPS location every 5 seconds, and would like to save this data to ESP and after checking the GPRS connection is active, just send it to my webserver. So I guarantee the loc...
