How does the Tx power impact the scanning and connection with a peripheral?
In detail, say if the peripheral can advertise at a Tx power of 4, 0 or -4 dB, then will it depend on the central's maximum(or device manufacturer's default value) of Tx power when it scans for the peripheral or not.
If the central can not exceed a power of 0dB, then does it make logical sense to have the peripheral advertise at a power of 4dB?
Also, we know how to manipulate the power for a peripheral, but are we allowed to change the same for a Central(an Android or iOS device)?
