I am using SmartRF Studio 7 to control CC2541. If I measure the sensitivity in BLE mode or in Proprietary mode with High Gain or Standard Gain, I get very different results. I use the same packet and just change the LNA gain. When using the BLE mode; High Gain has better sensitivity than Standard Gain which I would expect. When using Proprietary mode, High Gain always has lower sensitivity than Standard Gain?? Not sure why.
thanks
