Hi,

I have websocket client connecting to my websocket server in the cloud to send some data but I cannot get it to connect. I have tried with a Python script and some Chrome websocket plugins and they all work, I can connect, send and receive data. When I try to connect I receive the following two ...

Hi! The schematics in general look ok but there is no antenna, so if you are intending to use this with Wi-Fi or BT/BLE then you are not getting far. I would suggest you using a ESP32-WROOM module or similar. These modules deal already with memories, antennas and all essentials you need to run the ...

Hi,

I'm not able to get my esp to connect to a desired server, it always returns error "HTTP_CLIENT: Connection failed, sock < 0". By doing some research on the esp forums etc I found that people were having problems to make their DNS to work when running the ESP32 on either STA or AP mode.
Now I'm ...

Hi,

I'm trying to implement Modbus over TCP since I saw on the documentation that the TCP mode was already implemented as well as RTU and ASCII. When I tried to configure it I couldn't find any documentation and I read on one of the topics in this forum that back in July you guys were discussing ...

Hi WiFive,

I had no idea espressif had already implemented it. This solves my problem right away!
Thank you very much for your help!

The thing is that when I call INCBIN(arrow_48_left, "arrow_48_left.bin") and I ...

Hi again,

Found the problem. It was my ftdi USB/UART bridge which wasn't very good soldered. I checked the "Establish Serial Connection" page and connect the ESP32 to my computer. I get data but with weird characters. I could distinguished a "June" word but nothing else. Here comes a screenshot. I ...

Hi,

@ESP_Sprite
Thank you for the information. Glad to hear that it already has a bootloader.

@krzychb
I didn't check the "verify serial connection" site, I will do check it out. Also I will try to enter the bootloader manually without the "transistor's circuit". Thank you for your reply

Hi,

I am new to this forum so sorry if this topic already exists.
I am developing a PCB with some sensors and I bought a ESP-WROOM-32 to use to send data to my server. The ESP32 is soldered onto the PCB and all connections are correct but I am not able to flash it. I am using the transistor ...
