DIO3 in JN5169 is not accessible

[rajardeshna]

Hi,

I want to use DIO3 in JN5169 chip for LED indication, but I can't able to change it's state. Other DIOs are accessible and I'm able to change their state.

I have read this in datasheet: "DIO3/RFTX is asserted when the radio is in the transmit state and similarly, DIO2/RFRX is asserted when the radio is in the receiver state"

What does it mean?

If you are using a high power module and have enabled this in your application by calling vAHI_HighPowerModuleEnable or vAppApiSetHighPowerMode then DIO2 and DIO3 on the JN5169 are used to control the external PA/LNA and so should not be used for any other purpose. Otherwise they should be available for you to use to control an LED.
