Cool! But is there a way to use a mp3 file as input instead of microphone? I'd like to do something like phone-bot for my home

Juan_Antonio · July 3, 2023, 10:23pm

The easiest answer would be to send the .mp3 file

yeet · July 3, 2023, 10:25pm

send mp3 as text and then playback it at remote device?

Juan_Antonio · July 3, 2023, 10:29pm

One idea would be to convert the file to Base64 and send it using UDP, I haven't tried it with large files.

Juan_Antonio · July 3, 2023, 10:33pm

Try

Jhon_Hermes_Hernande · July 4, 2023, 1:58pm

i want use in network wan over internet not in lan, one idea

Juan_Antonio · July 4, 2023, 4:07pm

I haven't tried it, but maybe opening the port of a local network (NAT) can be achieved.

Jhon_Hermes_Hernande · July 4, 2023, 8:21pm

I did it

yeet · July 4, 2023, 10:12pm

125kb file is too large even when at base64 (it isnt sending)

edit: 64kb is still too big

yeet · July 6, 2023, 1:21am

what did you do to achieve this?

Jhon_Hermes_Hernande · July 6, 2023, 2:24am

What he said @Juan_Antonio i did it, i mounted server and not found the devices

yeet · July 6, 2023, 3:29am

ok, i interpreted your "I did it" as success

Juan_Antonio · July 6, 2023, 8:20am

Another idea would be to install an FTP server on a PC.

yeet · July 6, 2023, 7:40pm

great idea! but the is one problem with your extension (ftp) it causes a dx compile error

Juan_Antonio · July 6, 2023, 8:13pm

I can "Build" p174C_extension_FTP.aia

yeet · July 6, 2023, 10:13pm

compiling p174C_extension_FTP.aia works

but when i try to compile udp+ftp app (removing ftp builds the app) i get this:

What does it mean? "compile udp+ftp app (removing ftp builds the app)"

I can compile with extensions UDP and FTP
