Hey everyone,
So i have this projects where i should be controlling a BLDC motor wirelessly. I should make it at least start and stop just by entering certain character on the keyboard. BTW, im using the latest Teensyduino and a CC1101. As a newbie, i really dont have any idea except that i send something to the receiver as i have two CC1101, and only after the receiver got the data, the program of my BLDC Motor start to run. But after weeks trying to figure out, i am still lost as the data that received (im using the command of Serial.vailable and Serial.read )is always a -1. Just for starting the motor, i might just use the value of -1. But i cant have any other command as it only have "-1" value regardless of what ever i send on the transmitter.
here is my transmitter code
and here is the rx code.
Help this newbie
