Issue sending negative code

[kiki51]

Hi

I use rpiutils tools to send and receive code over 433mhz with my remote/plug.

I use it under home assistant to power on /off my plug. It replace my remote.

I have buy another set of remote and plug ( otio model. Ref 09ha2) which works fine.
But when I use rfsniffer command to find the remote code sent by the remote, the result is a negative code like : -1094193664.

After that I use codesend with this code and the sniffer return :
Received 13102592.

So I can’t send a negative code, it’s translate like a positive code. And it doesn’t work.

Can you help me to solve this trouble?
Thanks.
Sorry for my bad English.
Eric

The reason for the negative values is called "integer overflow". Your transmitter sends a code higher than the current data type (signed integer) can store, its like you want to count to 6 with 1 hand. You can count to 5 and then you have to start again for 5 to 6. Here its a signed int [-2147483648, +2147483647], just a bigger number.
