I'm a noob on electronics and I've been trying to send data from a Circuit Playground Express to a Raspberry Pi with a 433MHz rf link kit. I followed a Rasperry Pi tutorial with the rpi_rf.py library and worked well. Later tried rewriting the library to include Circuit Playground Express libraries for digital output instead of the Rpi GPIO, however, although I have made various tests to prove the existence of the data, the receiver is not finding any signal from the transmitter. Is it possible that the Circuit Playground Express is just not capable of doing this? Or am I just not trying the right way? Thanks in advance.
