uses when scanning for available devices (inquiry) or when establishing new
connections to other devices (paging).
In this way, the working range within which remote 750-644 I/O modules or
Bluetooth
connection has been successfully established, the transmission power can again be
automatically adjusted to the needs (see "SetMaxTXpower" command).
The "defaultTXpower" parameter is always equal to or less than the
"maxTXpower" parameter (value between 0 and 20 dBm).
Mobile Devices
If the "defaultTXpower" is significantly less than the "maxTXpower", mobile
devices can easily increase the distance from one another when communication is
stable. When rebooting or the connection is lost, the devices may be unable to
reconnect.
