Hello.
How can I decode signal 1527?
Can Ldmicro be used?
Please, can I get help?
Thanks

Ihor and others, with those simple transmitters / receivers you have to pay a little attention.

I also experimented with this and at one point I had a lot of problems opening my car with my remote control.

As it turned out, that 433 transmitter was always ON and disturbed the entire environment, because the UART port is at rest on 5v so that the transmitter always broadcasts (without data).

It is better to invert the signal on both sides with an NPN transistor.

CMT2150 + Encoder 1527, CMT2210 (by Andrea)
Hello. Thanks for the quick response!
Please look at the photo, I use the CMT2150 transmission chip + 1527 encoder. The CMT2210 chip for the receiver.
How can I acquire the packets transmitted by the chip and pair the signal?
