So I've been having a similar problem, see this forum post and issue #3686 . Maybe we can compare notes. I have an example project here that might help for debugging and sharing information. Regarding the sample rate calculation, note that using the APLL is explicitly (but not super clearly) warned ...

This question relates to issue #3686 . I am trying to use the I2S direct-from-ADC functionality, operating in stereo. I'm using the Wemos Lolin D32, which uses the ESP32-WROOM-32, developing on Ubuntu 18.04. My IDF version is v3.3-beta2, but it requires hacking on the IDF a bit to expose the necessa...

Sorry, not sure why BBCode isn't working there, it was not disabled.

I'm trying to debug a I2S/ADC application. I'd like to inspect the I2S registers to make sure they don't change, in particular the I2S_RX_SHORT_SYNC, I2S_TX_SHORT_SYNC, I2S_RX_MSB_SHIFT and I2S_TX_MSB_SHIFT registers. The following code just sets them and reads them straight back: [Codebox] void app...

I realised later this was a pointless exercise since this enables DNS client calling code, not server. Still, now I know.

Arg, I needed to define DNS_LOCAL_HOSTLIST as well! Putting this in the component or main CMakeLists.txt does the trick:

Not even this seems to work (in the top level CMakeLists.txt, same one that has the project() def): component_get_target(LWIP_NAME lwip) message(STATUS "LWIP target name: ${LWIP_NAME}") target_compile_definitions( ${LWIP_NAME} PUBLIC DNS_LOCAL_HOSTLIST_IS_DYNAMIC ) It sets the macro for my source fi...

I would like to add the ESP device itself to LWIP's local list of DNS entries. To do this I need to enable "dns_local_addhost()" by defining the "DNS_LOCAL_HOSTLIST_IS_DYNAMIC" macro (see lwip/dns.h). But I can't figure out how to do this via CMake. It can't be done via sdkconfig.defaults because ES...

...we haven't seen any 5 minutes inactivity state after getting disconnection event. But you can do wifi connect API again on disconnect event. Let me clear if i am wrong or misunderstood anything. I think this is what you are misunderstanding. It is not after the disconnect event. It takes 5 minut...

Just want to add: I also found this very confusing. The documentation starts off by showing how to add your own unit tests in a component, but it turns out it's only meant for ESP-IDF's internal components, so who exactly is the documentation targeting?

That aside, how could I achieve this via CMake?
