What case affect the communication range.

[jhc]

Hi,

I found the communication range using FREERTOS is shorter than which are using non-RTOS.

I know the RADIO TX power and the PHY rate affect the communication range，but there are any other factors could affect the commnunication range?

Thank you!

 Using any RTOS or not should not affect the range of the connection. As you mentioned, it depends on PHY/Radio sensitivity and TX power.

So how can I modify the Radio sensitivity. I am using SDK15.2.

sensitivity is fixed per chip variant and the protocol/PHY selected.

You can configure the TX power though.
