It sounds like maybe the beacon gating of the TX queue is not functioning?

It just meant the initial NF calibration during interface setup didn't complete very quickly, so it's delaying the CCA load (as the values needed aren't yet available.) The initial NF calibration can sometimes take quite a bit longer than 10ms. Adrian
