I've been working on a project of automating my Carrier 42QTD018R8S Air Conditioner in order to be able to control it from HomeAssistant IO. As I have kernel 4.19, I followed this link in order to install and configure LIRC. My AC IR remote is Carrier RG56N/BGEF. I managed to record signals using irrecord, but when i tried to send for example ON code using irsend; Here is the circuit for IR transmitter. I could see the IR LED blink through my smartphone, but my AC didn't turn on. Does anyone have any suggestions as to what should I try to do in order to properly send the code to control the AC?
