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...

Re: esp32 internal temperature sensor

Thank you for sharing your experience, I am very grateful.
I will do what you indicated, I will be estimating the temperature by comparison, then in practice I will reach more accurate values.

Thanks for the help, hug!

Re: esp32 internal temperature sensor

Yes, I saw it in the datasheet. But I had doubts, because at a temperature much lower than 125 ° C some plastic materials melt. But this temperature of 125 ° C is the internal temperature, and this is what I will be monitoring. I have this concern, because my device will operate on vehicles, and veh...

Re: esp32 internal temperature sensor

Thanks for the answer. I got the same result I was getting. I was confused, because the result was 140 ° F or 60 ° C, so I wondered, what will this temperature be like? it is very hot, and the ambient temperature I am at is 19 ° C or 66.2 ° F. I want to control the temperature of the device, so be w...

esp32 internal temperature sensor

I can not read the internal sensor temperature of esp32. For I do not know which unit of measure is the integer value that I am receiving. The [esp32.raw_temperature ()] command returns a value that I convert to Kelvin, Celsius or Fahrenheit, but no value of the result makes sense. How do I convert ...
