Re: Faster DHCP IP

Thanks for reply. Ok, do you have any idea on how to do the DHCP caching in RTC memory? I have no idea on how to basically set an static IP on the ESP32 with the esp-idf :(

Faster DHCP IP

Hello I'm currently trying to do a HTTP Request as fast as possible after a deep sleep (to consume a as low as possible energy to save battery life). Thus I'm using deep sleep I'm fine with caching informations in RTC memory. Is there a general way to speed up the DHCP negotiation process? (That's c...

ESP32 JTAG Debugging

Hello I'm currently trying to get my ESP32 WROOM on the Devkit connected with an FT2232H FTDI Adapter. I hooked up the 4 JTAG Lines. No Reset. When I try to flash the binary via JTAG I get the following Error. Is this a common fault? I already tried lowering the Speed from 20M to 5M. $ sudo bin/open...

ESP32 WROVER pSRAM Quiescent current

Hello

I'm just asking if and how big the difference of the quiescent current between the ESP32 WROVER and ESP32 WROOM Module should be in deep sleep mode.

Thanks

esp_log_set_vprintf

Hello, I'm trying to redirect the log outputs to my MQTT Server instead of UART0. But I'm not really familiar with the used vprintf, nor did I find this function in the esp-idf github repository. I tried the following to "redirect" it to printf, but just got an Exception while trying: int redirect_l...

Regulator ESP32 Deep Sleep

Just want to ask what you guys use typically for a Regulator for Low Power Applications with the ESP32. I haven't found the "perfect" one yet. Obviously SMD.

UART Debugging Deep Sleep

Hello, I have an CP2102 connected to the TX and RX of the ESP32. Whilst deep sleeping I turn the CP2102 off (No 5V, internal 3.3V regulator thus dead too). The ESP32 still "feeds" the CP2102 through the TX Line of the ESP32. How can I turn off the Debugging UART Peripherie? I already tried to uart_d...

ESP-WROOM-32 esptool fatal error

Hello I'm currently in the process of getting my board up and running. I used a new WROOM module and placed it on my board. My board features an CP2102 Serial converter. I verified a working auto prog circuit (same like on the Espressif Boards) with toggling the pins in Realterm and thus putting the...

Re: UART Timeout doesn't work

hmm, but it doesn't work either with 50, 500, 500 / tickrate.
