Re: How to transmit video faster via wifi?

I ran on similar issue with BLE. I had to put a delay between sends.

I guess the question how can I query the remaining memory available ?

Re: BLE Indication crashes

Yakes!, this still don't solve it! It resolve the exception, but the code silently fails, since the "deep_copy" callbacks can't return errors, even though they might fail due to lack of resources ( memory ), they log errors, but the caller can't see the silent error and return "OK&quo...

Re: BLE Indication crashes

Hi there, Since I did not get any answer, I've decided to go deep on this. The issues were with the BT stack. Below are the fixes. I don't know if that is the best way... My expectations were right, and the memory allocator was not checking for errors.... Thanks! The diff is bellow. diff --git a/com...

BLE Indication crashes

Hi all, I am wondering if you could give me some hints on where to look. I am sending packages of around 100 bytes from a set of sensors, and sending them in batches. Most of the time, the ESP32 reboots with an exception. If I place a "delay" of 100ms between indications, it runs for long ...

If I use any std C++ stuff, and I include "stdc++ library, I get this link error: /opt/esp32/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/4.8.5/../../../../xtensa-esp32-elf/lib/libstdc++.a(vterminate.o):(.literal._ZN9__gnu_cxx27__verbose_terminate_handlerEv+0x8): undefined reference to `_im...

Re: After ESP-IDF 1.0...

It is really good to know that the Analog ( read/write ) drivers are about to be merged. I am really looking forward to it.

Thanks for the BLE component, very impressive what was released.

Re: Arduino Dev without Arduino IDE using makefiles

Yes, thanks

Without the SysLink it works!

Thanks to all for the help!

Re: Programming in C++

I've not met any issues with freeRTOS, only noticed a lot of defines ( not as all caps like: THIS_IS_A_DEFINE ) or something like that, which could lead to issues. Only noticed a possible for naming clashes due to all macros. I met issues with the lwip headers. I apologize, I should not have used th...

Re: Programming in C++

There are serious limitations when using C++, specially if you include headers from freeRTOS or lwip components. Some headers in these components have a huge amount of "defines" macros as function names, and they clash with any method name that equates with one of these "defines"...

Re: Arduino Dev without Arduino IDE using makefiles

Thanks to all for the answers. I like the approach of using Arduino wrappers as a "component", since it does not add any extra dependency, and it seems inline with everything else. But, I downloaded bot gits, and inside esp-idf "components" folder, I added a syslink to the "...
