Re: Compatibility between "normal CMake" and ESP-IDF

Hi permal, Edit: build-esp32.sh in examples/build_system/idf_as_lib is hard coded for Ninja, on Linux make is usually the preferred tool. This should also work with make, if you change the shell script. (BTW, you might find that you like ninja - I'm a Linux user and I am 100% converted to it - build...

Re: Will ESP32-WROOM-32U be damaged if operated without an antenna?

Hi Phil, It can be damaged, and for this reason it is not recommended to any enable RF transmission without a suitable antenna connected. Anecdotally, I ran an ESP32 without an antenna connected for a while (without noticing) and it seems to be fine. But this is not a guarantee that all such cases w...

Re: how to fix: OSError: [Errno 71] Protocol error

Hi nobbynobby, Looks like you're doing everything correctly. The errno 71 "protocol error" usually means something went wrong at the USB link. You can try looking in the kernel log (dmesg or "journalctl -k") to see if there are any USB-related kernel errors at the same time flashing failed. I have a...

Re: Recover key from flash encryption

To expand on WiFive's answer, you can set this via: espefuse.py burn_efuse FLASH_CRYPT_CONF 0xF Also, there are a number of other efuses which need to be burned to make the device configuration secure. You can burn these manually, but the recommended approach is to have the device do all of this on ...

Re: Mbed TLS gives error while enabling GCOV

Hi vasu1234,

Can you give some more details about the error you're seeing, please? (ie exactly what are you doing, and exactly what is the ESP32 behaviour.)

Re: ESP32 crashes when try to execute code from IRAM

Hi isaque, Your short binary code looks like it should probably run. - If you capture both the full output of the panic handler (registers) and also print the address of f() before you call it, how does the PC address in the panic handler compare with the address of f()? Is it definitely crashing in...

Re: TLS handshake slow ?

Hi Danny,

There's normally some delay, but 7 seconds is very long! What cipher suite ends up being used for the connection?

Re: ESP32 BUG cause software brick

Damn. Maybe it's not related to core dump then, I was just going on the last log message before it froze. I don't know of anything in particular with this commit, but this is the problem with "Development" versions (-dev) - they have had some basic automated testing but they're not comprehensively t...

Re: Let's talk wifi and TCP

I may be beating a dead horse, but wifi performance in a busy office setting appears to be pretty bad. Hi John, Just to check all the variables: how is 2.4GHz WiFi performance for other devices in the same environment? ie if you connect a PC to the 2.4GHz network (ie same router, same frequency ban...
