GPIO4 LED blinks when BLE advertise

[NeDh_4602711]

Hello,

I am using WICED STUDIO 6.2 with CYBT-343026-01. and I have used GPIO4 to drive 1 LED. But the problem is that. When BLE starts its advertising it blinks LED automatically and I haven't used GPIO4 anywhere in code but still, it blinks. Is it possible to use that pin dedicatedly for other purposes?

I have tried by GPIO_OUTPUT_DISABLE to disable but it still blinks.

Thanks in advance.

Thanks and regards,

Neeraj Dhekale.

Hello NeDh_4602711 ,

I can see by default WICED_P04 is defined as PUART RX in platform files of CYBT-343026.

Is this the same pin you are talking about ?

If then please change as per your requirement.

Yes. But instead of WICED_P04 we are using WICED_GPIO_04 and expecting it should not blink.

Please check about WICED_GPIO_04.

Thanks and regards,

Hi NeDh_4602711 ,

Same pad is muxed with GPIO_4 and few other pins. So please recheck if you are using the same pins in your application or platform file.
