I have a question:
When I analyze the original transmitter and receiver, I can clearly see the transmission (12ms; about 200 bits; 58us H; 58us L). the signal is clear and decodable. Same with HDSDR, clear to see!
With all three RX868 receivers ( no i2c/SPI only DATA_OUT) only a rectangle of 12ms!
D0: RX868 Signal (12ms H)
D2: org. Send unit
D3: org. Receiver unit
Am I doing something wrong?
ELV Empfangsmodul RX868SH-DV, 868,35 MHz | ELV Elektronik | Bauteile / Komponenten | ELV Elektronik
Are the older modules (no SPI) not capable of FSK?
