IRsend to Toshiba AC splitter unit not working. Works with other devices

Other Hardware LEDs and Multiplexing
1

Hello
I have been trying to communicate to a Toshiba AC unit with an IR LED with no luck, But i can communicate with another AC unit and my tv's, sky box and so on basically everything but this Toshiba AC unit. I had to increase the #define RAWBUF from 101 to 230 so i could record the entire signal from the Toshiba AC remote. Once i increased the RAWBUF i was able to get the whole IR message but when i try to send it even 10cms away the AC unit does nothing, such as turn to turn it on and off.

Heres what i got by using IRrecvDumpV2. Could any one help me, I emailed Toshiba and they said that there are not willing to disclose the Braude rate, bit or frequency. No joke its known that Toshiba really dont want people knowing this protocol. I tried send it as seen below, i even used an incrementing code to try many frequencies and braude rates, with the RAW and SAMSUNG type, fyi IRrecvDumpV2 flagged it as SAMSUNG type code but again the unit is Toshiba.

Check the signal with a scope, maybe it's not 38kHz modulated.

Sorted, i just had to give it a length big enough to do it in one transition.
