I will add a the install guide later. sorry!

Installation

easy mode

hard mode

cd ~
git clone https://github.com/wisehackermonkey/netpirate.git
cd netpirate

balena login
balena push pirateship

balena ssh pirateship pirateradio

/bin/sh ./pi_fm_adv --ps RASP-PI
--wait specifies whether PiFmAdv should wait for the the audio pipe or terminate as soon as there is no audio. It's set to 1 by default.

hack to get text from api to file as characters, to morse code to wave audio file

echo "audio.wav" | entr -c ./pi_fm_adv --ps RASP-PI --wait 1 --audio ./audio.wav
echo "audio.wav" | entr -c cwwav -f 700 -w 20 -o hello_world.wav
echo "sos sos" > morse_data.txt
find . -name "morse_data.txt" | entr -r cwwav -f 700 -w 20 -o hello_world.wav morse_data.txt

find . -name "morse_data.txt" | entr -r echo "file changed"
echo "morse_data.txt" | entr -r echo "file changed"
echo "morse_data.txt" | entr -r cwwav -f 700 -w 20 -o hello_world.wav && echo "file changed"
echo "morse_data.txt" | entr -r | cwwav -f 700 -w 20 -o hello_world.wav && echo "file changed"
echo "morse_data.txt" | entr -r -s "cwwav -f 700 -w 20 -o hello_world.wav ./morse_data.txt"

echo "" > /usr/src/app/PiFmAdv/src/public/morse_data.txt && echo "morse_data.txt" | entr -r -s "cwwav -f 700 -w 20 -o hello_world.wav ./morse_data.txt"

./pi_fm_adv --freq 90.7 --ps RASP-PI --wait 1 --audio ./hello_world.wav 
echo "oran was here" > /usr/src/app/public/morse_data.txt
echo "oran was not here" > /usr/src/app/public/morse_data.txt

testing mp3 file pipe support

sudo apt-get install libmp3lame-dev
make clean 
make LAME=1

didnt work. sad face emoji

adding env for setting radio station frequency

balena envs --fleet pirateship

nevermind i just added it to the docker compose file
