I have an RCA/Curtis RTU4300 4k tv that I lost the remote to, and I tried 5 different universal remotes with no luck, and an internet search has shown that I am not alone. In the manual, all I get is that it is NEC protocol with a universal remote code of A05F and then a 2 digit hex for each button, such as 5F for Power. I attached a screenshot of the manual.
I can not figure out how to use this, and I can’t find info anywhere, as it all seems to deal with learning the codes from a regular remote, but not making them once the remote ihas already done a runner…,. I THIINK that I just put my code in front of the hex, such as “A05F 5F” for power, then convert to decimal? However, I get a 10 line number using the yamaha nec to decimal converter.
I am trying to do a universal remote with an ESP8266 to control my tv for now and maybe expanding in the future. How do I go about doing this? Primarily I just need volume, menu, direction buttons and some number keys to get into advanced factory settings. Thanks!
