I just finish building a local server on Raspberry Pi 3 B+, from Blynk app, I can register new account, connect to the local server and send out the email for authorization code.
I do have a project that was working fine when using Blynk hosted server. The same project will not work when I switch to local server.
Here is what I did when switch from cloud to local:
add the below to current project (my local server IP)
char server = "192.168.1.20";
Add the “server” to the end like
Blynk.begin(auth, ssid, pass, server);
when running the compile, nothing output on the serial monitor
By remove the word “server” then serial monitor can display the output result as it is now using Blynk cloud server
Blynk.begin(auth, ssid, pass);
What did I do wrong? please help.
