Re: can't redirect console output (regression)

Thanks for the offer. At this point, though, I'm still wondering how it is that it works for the hello world example, but not for my app. As stated above, the sdkconfig files are nearly identical (I have to build my app in release mode due to size constraints), and the partition table is identical....

Re: how can I get wifi rssi at faster rate

Hi Red_A3, My question is: How can I access (pass my own values) to the other config parameters " using Arduino IDE "? Namely, I'm targeting the bssid and channel parameters. Is that possible to be done without recompiling (rebuilding) the esp-idf arduino library (after passing those parameters in t...

Re: can't redirect console output (regression)

Unfortunately, using v3.3 yields the same (erroneous) behavior for my app as did v3.3-rc. That's interesting, maybe I'm wrong about exactly when the regression was introduced (I didn't test any v3.3 revisions at all.) If you'd like a temporary patch to fix it on either v3.3 or v4.0 branch, let me k...

Re: can't redirect console output (regression)

1. As I mentioned above, this all came about when I tried to migrate to IDF release/v4.0. When I returned to release/v3.3, however, the problem persisted. I had assumed that the release/v3.3 branch was immutable at this point, but perhaps I was mistaken. If it isn't immutable, which IDF should I us...

Re: Allocate 2 buffers in specific address at different memory banks

I think that i need to enable the i2s module with "periph_module_enable(PERIPH_I2S0_MODULE);" before i change any i2s module registers. Correct. Not every piece of code here is controlling I2S module (for example, GPIO Matrix configuration), but it can't hurt to do this as a first step. "periph_mod...

Re: can't redirect console output (regression)

I'm able to reproduce this with release/v4.0 branch and these settings and also setting flash to DIO mode: Custom: UART1, TX= GPIO10, RX=GPIO9, These pins are also known as SD2 and SD3 and are connected to the internal flash chip when using Quad I/O modes. Some fixes for SPI flash performance went i...

Re: lwip accept => error 23 (Too many open files in system)

but in general, calling lwip_close after recv returned -1 should be enough to close the socket? Yes, this will close the socket at the ESP32 end. Of course, it only works if recv returns -1 first (ie the other end has closed the socket and isn't holding it open, or some packet loss meant the RST pa...

Re: lwip accept => error 23 (Too many open files in system)

Hi Torsten, LWIP has a limit of the maximum number of sockets in the system. ENFILE (23) will be returned if this limit is reached: https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/kconfig.html#config-lwip-max-sockets The solution may be to either increase this limit in the projec...

Re: Non-LWIP Compilation

Maybe I misunderstand - how am I going to get lwip to compile along-side mine if tcpip_adapter's involved? Should I specifically be using the esp_idf's tcpip_adapter.h but my own tcpip_adapter.c? Yes, you can still replace tcpip_adapter component with your own - and make whatever changes you need, ...
