For now, the diversity settings are controlled by 'txantenna', -not- rxantenna. This is because the earlier chipsets had controllable TX diversity; the RX antenna setting twiddles the default antenna register. I'll try sort that stuff out at some point. Call the antenna switch function from the board setup function so scans, channel changes, mode changes, etc don't set the diversity back to a default state too far from what's intended. Things to todo: * Squirrel away the last antenna diversity/combining parameters and restore them during board setup if HAL_ANT_VARIABLE is defined. That way scans, etc don't reset the diversity settings. * Add some more public facing statistics, rather than what's simply logged under HAL_DEBUG_DIVERSITY. For now, the fixed antenna settings behave better than variable settings for me. I have some further fiddling to do.. Obtained from: Atheros
