Hi all,

I use CC2541 + stack 1.4.2.2, I want to transmitt IR signal.

Is it possible to do that? if not ? Can I do it if I use CC2541?

Thanks,

Hi,
Thank you for the response.
I get source code IR generation on CC253x. Then I ported the IR Driver code for NEC format from the "hal_irgen_NEC.c" file from the "IrGenApp" for CC2533. I am trying to use the code for CC2541 chip. I ported the HalIrGenInitNec(), HalIrGenCommandNec(), HalIrGenDmaIsr(), and startIrGenNec() functions in my simpleBLEPeripheral.c. I called HalIrGenCommandNec(0x04FB08F7) in the SimpleBLEPeripheral_Init(), in while(1) with delay 500ms, I did not see any output in P1_1.

Can you please let me know, where am I wrong or am I missing anything?

Thanks
Tuan
