Hi guys
I'm trying to read weather data from api.open-meteo.com . I know this should work , since I did it using Arduino IDE . When I try using Flowcode v10 and ESP32_wroom32 , can't connect to the server . Tested on local network using "TCP Terminal" as server on my laptop and esp32 it will connect and send the GET request .
Any reason why can't connect to open-meteo ?
Help please
Thank you

Re: Connecting and reading data from api.open-meteo.com
Hello,
Your connecting to HTTPS "https://api.open-meteo.com/" on Port 80. I beleive this should maybe be 443.
Or try connecting to the non encrypted HTTP version instead "http://api.open-meteo.com/" on Port 80.

Hi Ben
Should be http and port 80 , unfortunately no luck . Don't know what Arduino does different .
This is definitely to much for my brain .
Thanks

Hi
From looking at your chart I assume you have issue when the Network Comms component tries to connect. If that fails it won't matter what your api string consists of.
I might be wrong as it has been a while since I last used, but I'm pretty certain you don't need to include "HTTP://" in NetworkComms address. I can (if I rember correctly) connect with just numerical address 123.456.789.123 or a variable such as "abc.com"
Regards

Hi
Further to above you seem to be sending out "debug" info over UART2
After you open a socket you send out "Connecting" then attempt to connect using NetworkComms1.
If you the sent out the value of "socket" over UART2 immediately after, you would get notification of success/failure which may help you debug further.
If you cannot connect it doesn't matter what you send later.

Hi
There is no attempt from esp32 to connect to the server if I use "api.open-meteo.com" . After I used ping command to find out the ip address , witch at this time is "94.130.142.35" , the result is using port 80 and 443 :
"HTTP/1.1 400 Bad Request
Server: nginx"
<html>
<head><title>400 Bad Request</title></head>
<body>
<center><h1>400 Bad Request</h1></center>
<hr><center>nginx</center>
</body>
</html>
From what Google is saying , this site accept connections only using his web address api.open-meteo.com .
Maybe is something wrong in the code of the networkcomms esp32 component ?
Need an idea on how to test that .
Need some suggestion's please .
Thank you
