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!
