Dipole Antenna Elixir Project! ๐ป
- Listen to a Flex Radio TCP stream
- Parse VITA49
- Based on antenna/frequency turn on/off relay switch via Raspberry Pi GPIO
- Relay switch dictate dipole mode on antenna
This is for my Dad ๐
We are both HAM radio operators ๐
FLEX_IP
known IP address of the Flex RadioFLEX_RPI
if the server is running on a RPI with GPIO
- You do not need to define the FLEX_RPI var but you can set it to 0 or 1.
- 1 being that GPIO is on the system and the wiringPi
gpio
CLI is available for use. - 0 means no, and not defining it means no as well.
Example use on a rpi:
FLEX_IP=10.0.0.192 FLEX_RPI=1 mix run --no-halt
- Unexports all pins
- Exports mode out for BCM pin 17
- Opens TCP
:gen_tcp
connection to flex - Send a recieve all msg to flex with
:gen_tcp
(need to CLRF msg string) - Recursive loop recv with
:gen_tcp
- Parses recv msg to check for antenna and frequencies
- Based on antenna/frequency turn on/off relay switch via Raspberry Pi GPIO
Forever!
