Re: Override lwipopts.h

Which settings? I am trying websocket app that sends 1k of data every 100ms, and I see data stops sending at some point. I'm not sure but maybe I ahave problem with Maggie algorithm... From Wikipedia Applications that expect real-time responses and low latency can react poorly with Nagle's algorithm...

Re: Simple profiler for IDF Monitor

Very nice tool! :!: Thanks!
Can you show printf line where you print micros() - I think this is needed for profiler to properly read time diferences?

Re: WIFI_MODE_APSTA Sample

I am looking into arduino sample for esp32. There is: #define WiFiMode_t wifi_mode_t #define WIFI_OFF WIFI_MODE_NULL #define WIFI_STA WIFI_MODE_STA #define WIFI_AP WIFI_MODE_AP #define WIFI_AP_STA WIFI_MODE_APSTA So I can assume there is AccessPoint mode Station mode and AcccessPoint and Station mod...

PWM interruts when duty is changed

Hi, I am trying 20kHz pwm on arduino esp32. My source code is https://github.com/zhivko/BleVogaLifter-esp32-DRV8703Q/blob/master/src/Server.ino and the result of changing PWM is seen as gap in pwm. Please see recorded video of pwm signal from above sismple example - PWM is still interrupted: https:/...

Re: ESP32 Minimum Hardware

Schematic for minimal hardware with resistors on gpio0, and EN and buttons would be much appreciated (plan to use it with USB to logical level RX/TX adapter).
Anybody has this schematic?

Re: Loading image via JTAG adapter

Flashing over JTAG would be really neat. Using 2 cables is not fancy ;).
@ESP_Angus: do you see this could be implemented in near future? I think it would help the platform to become mature and allow users to easier catch all this possible nasty bugs thata could happen during devel cycle.
