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...

Re: My new PYB Nano board is coming

@nebenzahl Is PYB NANO better than an ESP32? It is different. Generally, the PYB NANo is based on the STM32F401CE, which has less RAM and flash memory than the ESP32. So code size is limited. And there is no WiFi or Bluetooth. BUT, being based on the STM32, timing is much more dependable. If you ha...

Re: My new PYB Nano board is coming

Yes TAOBAO is very complicated for non-chine. You have to find a way to put in Aliexpress, otherwise the number of customers will be very limited. I really want to buy your product and maybe use it in my commercial projects, however it has to be in a channel that I can buy. For me who live in Brazil...
