Likely solution, in that case: wire an 10uF capacitor between your EN and GND pins. The power supply is likely coming up slower than the duration of the reset signal as generated by the on-pcb RC network, leading to issues. I did that. The ESP boots and the AP is visible, but I can't connect to ESP...

What type of capacitor do I need to use ? Any type should work. I've soldered a 10uF capacitor on the ESP32: the DevKit V4 Wroover-B between EN and GND and the ESP finally boots. I have tried powering the ESP using 5V and then 3V3. In both cases the AP is visible but I can't connect to it. I still ...

On the boot issue: Does it boot when you momentarily connect EN to GND? Yes, it does. And after it boots I can also connect to EPS's AP; so it works as intended, but only after briefly connecting EN to GND. A drone battery should have enough current to deal with esp32 current spikes in WiFi mode bu...

I am continuing an issue that I have opened here: https://github.com/espressif/esp-idf/issues/7127 Development Kit: ESP32 Wemos Module or chip used: ESP-WEOOM-32 IDF version: v4.2.1 Build System: [Make|CMake|idf.py] Compiler version: xtensa-esp32-elf-gcc (crosstool-NG esp-2020r3) 8.4.0 Operating Sys...

Do you have enabled PSRAM? It is wrover module and pins 16, 17 are used by PSRAM. It is the Wrover-B, yes. But I have no idea if the PSRAM is enabled. How do I check that ? I have changed the pins to: #define RXD2 22 #define TXD2 23 void setup() { Serial.begin(115200); Serial.println("Started."); S...

I would like to implement the TF02-Pro with the ESP32. I know that it works with Arduino so I've assumed that it will work with ESP as well. Board: Wrover-B Devkit 4. The TF02-Pro has 4 wires defined as: red +5V, black GND, green TX, white RX. I have connected them as follows: Sensor 5V to ESP 5V; S...

Hello. Have you ever made this work on the ESP32 ?

Don't connect 5V circuits to the esp32. You will need to use a level shifter.

Reading through CubePilot documentation it seems like the ports operate at 3V3
