Hello,
The data sheet for BlueNRG-MS specifies the tx power from -18 dBm to +8 dBm. However, the data sheet from SPBTLE-RF, which embeds the BlueNRG-MS, specifies the maximum tx power as +4 dBm.
Where does the 4 dB loss come from? Does this mean, that the real tx power range for the SPBTLE-RF goes from -22 dBm to +4 dBm?
Is it correct, that the SPBTLE-RF uses the JOHANSON P/N 2450AT18A100 antenna (see FCC document), which would result in an antenna gain of -0.5 dBi?
