I've found CyBle_SetTxPowerLevel(0) in a program called Proximity Bonding, peripheral. It's purpose is to reduce the advertising transmitter power to such a low level that in order to bond a central device must be placed within a cm or two of it. This seems to work sometimes and not so much at other times.
I've been unable to find any documentation that talks about the parameter "0". All I've found are indications (enum) that the value can be from 0x01 through 0x07.
Is the use of "0" legit and, if so, what does it really mean?
Thanks for your help,
Dennis
