Just a few thoughts. I've done a lot of work recently on the AP interface - here is what I found and it may help shed some light on your issue. Check your event callback and see if you are issuing a esp_wifi_connect() in response to an event. If so, you may need to rethink exactly how you do that. L...

Just me 2 cents on your question. Are you in AP only mode or APSTA mode? The events you are getting is from the AP wifi interface. You are seeing clients connect and disconnect to your access point. You can not lose your access point. The event you are asking about is a STA event. Those events are a...

I removed lwip as the stack over in ESP8266 RTOS V3 IDF and ported in a different stack. The function that bridged the stack and the internal wifi transmit required an additional 36 bytes preceding the data (used for wifi headers) and need to be allocated from the DRAM heap (IRAM would cause a crash...

If the buffer passed to esp_wifi_internal_tx() comes from a standard malloc() call, will the buffer be proper aligned and of the correct "CAP" type for the function esp_wifi_internal_tx()?

Thanks

Thanks - found them.

I was looking at some installation guides that suggested they were located elsewhere -- I could not be found.

I followed the Windows Install process where it calls to download and run
esp32_win32_msys2_environment_and_toolchain-20180110.zip

After executing I have a complete msys2 folder but the toolchain was not included.

Nowhere can I find a way to acquire the toolchain to install it.

Help.

Thanks.

Look at esptool.py and see how they program it using the uart. Perform the same protocol via a uart in your external CPU. Besides the uart, you will need some I/O to control reset and I/O manipulation to put the ESP into programming mode. There are also a few C based ESP tools like esptool that are ...
