Re: UDP client does not start to send in AP mode

Firewall !!!

I missed a specific setting for public, non protected networks...

Alas, a stupid way to burn so much time, but at least it's working now.

Greetings

Re: UDP client does not start to send in AP mode

Hello everyone, I installed Wireshark to monitor the UDP traffic. Interesting finding: The ESP32 does start sending messages as soon as the station (my Laptop) has connected. BUT: non of my terminal programs starts displaying these messages before I send a line to the ESP32 (Hercules, YAT, script co...

Re: UDP client does not start to send in AP mode

Dear all, unfortunately I have to revise my last nights reply. If I give the ESP32 a full power cycle (not just make monitor), the connection to the terminal will not work prior to sending a message (e.q "1") to the ESP. I corrected/cleaned the code a bit and post it again here. Does anyone have a c...

UDP client does not start to send in AP mode

Hi to everybody, I have a problem with a UDP client setup: I start a DHCP server, then WIFI in AP mode. Once this is done I start a UDP client in a task. This works all without problems, I can connect to it with my computer, receive an address and start sending UDP messages. The bad thing is: I do n...

Re: WSL Ubuntu & Silabs CP210x => COM Port Problem

Hello Chris, thank you for your answer. I totally agree: if you are serious about it, go native! As I am hobbyist and have all my other computer programs windows based, installing a native Linux is not an option. I tried Msys32 before, this gave the impression of being slow, though I failed to time ...

Re: WSL Ubuntu & Silabs CP210x => COM Port Problem

Hi,

I solved this problem:

finding that the problem was caused by windows, I downloaded another driver.

The one on the SILICON LABS web page does not seem to work.

I now use the one provided by Pololu, which works fine with Windows and WSL Ubuntu.

Sorry for bother you,
hope I helps others.

Re: WSL Ubuntu & Silabs CP210x => COM Port Problem

Hi everybody, I could narrow the Com Port problem a bit down: Driver: Silicon Labs USB to UART Bridge (Version 10.1.4.2290 Date 11/26/2018) a.) setting the driver as COM3 and booting Windows, entering UBUNTU -> Errno 5 on make flash or make monitor b.) setting the driver as COM4 and booting Windows,...

WSL Ubuntu & Silabs CP210x => COM Port Problem

Hi, being new to the ESP-IDF and Linux I hope that my question is worth asking it here. Searching the web I was not able to find a solution: 1.) In Windows 10 64x (1809) my ESP32 (HelTec ESP32) shows up as COM3 (Silabs CP210x_Universal_Windows_Driver) unplugging the device: it disappears In Device M...
