I have a WROVER-B and I am trying to use GPIO32,33,34 and 35 as buttons. So when I press the button, it should put the pin to LOW. The problem is that GPIO 34 and 35 are always LOW. #define RST_BUTTON 33 #define Input_1 32 #define Input_2 34 #define Input_3 35 pinMode(RST_BUTTON, INPUT); pinMode(Inp...

Hello. I am trying to use the following event handler : static void wifi_event_handler(void* arg, esp_event_base_t event_base, int32_t event_id, void* event_data) { wifi_event_ap_staconnected_t *event; wifi_event_ap_stadisconnected_t* evente; switch (event_id) { case SYSTEM_EVENT_AP_START: ESP_LOGV(...

Hello @GeorgeFlorian1 hmm, not sure what's happening here. Are there any errors in the log? Have you tried another power source, like an USB adapter or power bank? Thanks Felix I don't have other power sources. I can power up the ESP using an USB cable or using a 5V from the Flight Controller. I go...

Hello @GeorgeFlorian1 the ESP32 Wrover-B module has PSRAM, which requires GPIO 16 and 17 so you cannot use those for anything else. Thanks Felix I've moved to GPIO 18 and 19. These are connected to the drones RX and TX pins respectively. The measured voltages on these pins is 3v3. I am powering the...

Have you examined the source to determine under what conditions it might be stopped? What source ? I don't know what else to examine or do. In the latest attempt I've build and flashed the project using the esp-idf python tool and I am powering the ESP via the USB. Maybe it's because I tried using ...

Board: ESP32 Wrover-B DevKit v4 I am struggling to connect to an ESP32-Wrover-B's softAP. I have PIN 17 and PIN 19 acting as TX, respectively as RX. They are connected to a CubeOrange flight controller as I am trying to establish a serial communication. And whenever they are connected, the softAP wo...

I just compiled the project for my board using the ESP-IDF extension on VSCode, but I still have the same problem. I cannot connect to the AP. I can't connect with the PC nor the mobile phone. Sorry for asking a dumb question, but since you haven't mentioned any details... the posted code they have...

Did you compile it for your platform, or did you just flash the precompiled binary? The binaries were compiled and tested on a DOIT ESP32.

I have used the precompiled binaries. Huh, so that can cause issues ?
I will try to compile it for the board that I am using.
Thanks.

I am trying to use https://github.com/DroneBridge/ESP32 on a ESP32-Wrover-B I've flashed it using esp-idf-v4.2.1. I am trying to connect to the ESP's AP with my phone but it doesn't work. I keep getting the same two error messages on my phone: Couldn't authenticate connection Couldn't get IP address...
