She speaks serial! Let's hook it up to a UART.
Once I have the radio hooked up to a UART I attempt several times to capture data, unable to find the correct baudrate.
Having a hard time guessing the baudrate
Alright maybe there is a better way....
I found this website online and it worked out quite nicely.. https://www.kumari.net/index.php/random/37-determing-unknown-baud-rate
Using my Oscilloscope I was able to measure the shortest burst as suggested in the above link/website. This gave me a reading of about 800.0us in width which should round out to about 1200 baud.
Does she look good now?
Captain, we haz data!

Alright! We're not off to a bad start.
Stay tuned for more.
