Compiling esp-idf opens lots and lots of (source) files, and the antimalware tries to scan all of them. I think you can add the esp-idf directory to the do-not-scan-on-access-list; if I recall we have a bit in the esp-idf documentation about that.

- Topic: [SOLVED] UART response too late
- Replies: 9

The UART by default waits until a certain number of bytes have come in or a timeout happens before it tells the software to process the data it received. (The reason is because it would result in a lot of overhead if the UART would poke the processor for every byte.). You can change this by setting ...

I think technically they are snapback devices instead of clamping diodes, the idea is the same. However, officially we do not advise putting any voltage over what's stated in the datasheet on the GPIOs. For the few hundred millivolt, however, you could make a small resistive divider (1K/10K or so) a...
Hm, I initially thought that the library maker might automatically switch to HSPI if VSPI is full, getting to a total of max 6 devices, but on second thought that does not make sense. Without looking at their code, I can't tell what's up there.
The MAC is globally unique and not random, as it's given out sequentially to each ESP32/ESP8266/.... Espressif (and on a higher level, the IANA and the companies that bought address blocks from them) make sure that there are no devices with the same MAC anywhere in the world.

Additionally, most APIs in esp-idf are re-entrant; you should not have to use vTaskSuspendAll at all. (And if you think you need to use it anyway, use mutexes instead - the ESP32 has a fair amount of things running in the background, and stopping them all with vTaskSuspendAll is like using a cannon ...
