OOK with RFM69HCW: Sample sketch?

by drfritz142 on Sat Jan 19, 2019 5:06 pm

Hi there, I need to send an OOK or ASK signal @ 433.42 kHz. I want to control my window shades which "listen" to an RF remote sending OOK signals @ 433.42 MHz. If it were the “normal” 433.92 MHz I would have used a simple 433 MHz RF module. But at 500kHz away from the center frequency the receiver which I want to talk to doesn’t get anything anymore. I am pretty sure I can use this RFM69HCW module to set the exact frequency as I like to 433.42 MHz to match that of the receiver. The question that remains: is it possible to send simple ON/OFFs pulses using this module? I see in all the sample sketches I have looked at only these “packets”… Probably I am blind... can you help? Thanks in advance.
