Decoded signal is recognized fine by probe, but not by device

Hi there,

I am scratching my head around this one. Thanks in advance for any tips, I’m lost.

Issue

• Objective: Control a TV set from Arduino with IRlib2.
• Remote signals are decoded fine by IRlib2 on Arduino
• A probe on another Arduino acknowledges that the signal is decoded and resend alright.
• TV is ignoring the signal.

Process

Step 1 - On Arduino 1, I decode fine the signals from a Sony TV remote (see console logs bellow).

Step 2 - On Arduino 2, I send the decoded signal to Arduino 1, as a probe. Arduino 1 recognized the exact same signal that originates from the remote. Hence I deduct that both decoding and sending of a specific signal work fine and mimic the remote.

Result

From Arduino 2, I send the same signal to the TV set. Signals are ignored by the TV set, despite being recognized correctly by Arduino 2 to mimic exactly the remote.
