Hi Chen,
It doesn't work (based on my observation of RSSI I get from CC2531 USB packet sniffer, it's -20dBm with only
10 centimeters away from the antenna) .
CC2530 is configured for max TX power TXPOWER = 0xF5 (debugged), but it seems like the PAL/NA is acting
like a pipe (no amplification whatsoever).
Besides macRadioSetTxPower() is a low_level mac function, I think the right API function that should be used
in this case is ZMacSetTransmitPower(TX_PWR_PLUS_19) (don't you think so).
I have the filling i'm missing some sort of aditional compilation flag. Unfortunately I have not much time I can
dedicate to this, so I'm seeking for a quick answer from someone who is already using it (like you).
