it cannot be the case. Simply "free" comand outputs just a 5 digit number + prefix, which eats 212 bytes here is a captured output wp01:: 21612 wp01:: 21400 wp01:: 21188 wp01:: 20976 wp01:: 20764 wp01:: 20552 wp01:: 20340 wp01:: 20128 wp01:: 19916 wp01:: 19704

I have an application built with esp-idf v 5.1.2 on ESP32-WROOM-32 where I redirect all messages (logs, printfs, …) over TCP, to a server running ncat. So I have my own functions: my_log_vprintf(), my_printf(), my_fputs() which capture the output and send it to tcp, or to serial console, or disregar...

This is what i did. I replaced one of gptimers with an esp_timer. Looking on Lx6 brief about the interrupts, it says "support for up to 32 interrupts" and its configurable. Do you have any info about xtensa configuration flavour in esp32 different chips? Not sure if pinning could help. I can pin a t...

I have an application where i need to use the 4 gptimers. For all of the timers i have an alarm interrupt enabled declared this way static bool IRAM_ATTR x_timer_callback(gptimer_handle_t timer, const gptimer_alarm_event_data_t *edata, void *args) { ... return high_task_awoken == pdTRUE; } if all 4 ...

Looks like brownout detector triggered.
Maybe the power supply of your board dosen't provide enough current.

You don't need to change anything. @MicroController pointed you to the right places. Here is a small example bool wifi_join(const char *ssid, const char *pass, int timeout_ms) { int bits = 0; if(isConnected()) wifi_disconnect(1, NULL); wifi_config_t wifi_config = { 0 }; strlcpy((char *) wifi_config....

Looks OK!
Not sure if you have a Serial.begin(); in your setup code.
If you have it and still not working, then try the usb cable.
Either you cut it and solder directly D+/D- and GND wires, or let it as it is, remove R46, R47 and place R18, R19 and plug it in the connector.

How do you know you are able to load the code? Maybe its an issue with the way you generate rts/cts signals. I would try to use directly internal USB/JTAG i/f on pins 19/20. If i understood correctly your schematic, it just need a small rework. This way you eliminate usb/uart bridge and be sure esp3...

What do you plan to run on esp32, mqtt client or broker?
If esp32 is the client, then mosquitto is pretty good.
I use this combination esp32 client - mosquitto (running on ubuntu) since more than a year and its quite reliable.

Wiring looks ok, assuming you correctly identified the beginning of each motor winding. However i wouldnt let DRV8825 inputs unconnected, even they are internally pulled down. I cannot say how accelstepper library works, but arduino loop() function it loops forever. Hence setSpeed() and runSpeed() a...
