Graphics, sound and multimedia • Sending IR commands to a Thomson Android based TV fails

Hello,

I have an IR receiver and an IR transmitter attached via GPIO to my pi 5.

Using a Yamaha IR remote control my setup based on 'ir-ctl' works. I can learn a code and send it successfully to my AV receiver.

With the same setup using a Thomson TV (Android TV based) IR remote control it's not working --- the TV does not react. Protocol at the end of this post.

What could be the reason for this?

Regards

Josef
