Re: ESP32 WIFI webclient returns 400 Bad Request

Howdy Paulo, If I may suggest ... can you describe the nature of the error? While posting that "It doesn't work" and posting the source code is ok, it won't be as fruitful to getting you an answer as providing as much description as possible as to what actually happens when you do run the ...

Re: Changing partition size via OTA

I don't believe you can change the partition map using ordinary OTA functions. The partition map is a description of where in flash things are layed out. Within the partition map we can identify a number of flash areas that can be used to serve the purpose of OTA. These are the areas that are overla...

Re: Why each instance of my class consume 20byte of memory at least?

Its an interesting question ... (at least to me). I'm tempted to say that this is simply housekeeping. I think the detailed answer will come from examining a number of areas. The first will be memory management. We should assume that a class instance is carved out of the heap. This then begs the que...

Re: Decode url base64

There appear to be a number of C language routines on Github that claim to be URL decoders ... here is one that was posted 23 hours ago (from this date/time):

https://github.com/swarajsatvaya/UrlDecoder-C

But there appear to be many others.

Re: HTTP server simple example

Are there any settings in the MicroTik router than might have "blacklisted" your ESP32? Perhaps during testing you connected and disconnected too quickly triggering some kind of security routine that has said that your ESP32 is suspicious? If it were me, I'd probably get an un-used ESP32 a...

Re: Sending payload to AWS IOT using MQTT causes an error

In the sample code that you referenced, there is a line in app_main which reads() xTaskCreatePinnedToCore(&aws_iot_task, "aws_iot_task", 9216, NULL, 5, NULL, 1); This says that your task (aws_iot_task) has a stack size of 9K. This is why we are breaking. The solution is to either alloc...

Re: Use of cloud functions ... who are you using and what do you need?

Howdy Deouss and many thanks for taking the time to respond. If I may ask, what are the qualities you are liking of Azure relative to the other players? Is it just price? Are you connecting your ESP32 to an Azure cloud? What protocol does Azure use (MQTT?)? What are you doing with the data when it h...

Re: Sending payload to AWS IOT using MQTT causes an error

I have always found it useful to determine the exact line where an exception is being thrown. An advanced used might use JTAG source level debugging but quick and simple debugging, I sprinkle printf() statements and flush(stdout) into the code. This means that I can see the steps executing each stat...

Use of cloud functions ... who are you using and what do you need?

Howdy folks, As we know, cloud is an important force in our ESP32 world. I view this as the ability for our ESP32s to generate data and make that data available over the Internet. To that end, I envisage a cloud service provider. That provider makes available the capability for the ESP32 to transmit...
