5.3.1.4 Set RF Output Power (SGA,<0-8>/SGC,<0-8>)

Format: SGA,<0-8>/SGC,<0-8>

Command SGA and SGC adjust the output power of the RNBD451 module under advertisement and connected state, respectively. The input parameter is an eight-bit hexadecimal value, whose unit is dBm, assigned to the RF TX output power. The valid output power is from -25(0xE7) dBm to 15(0x0F) dBm. The following table provides details about the approximate output power (in dBm) for each parameter value. There can be a variation in output power based on the individual calibration of the module and the enclosure where the module is placed.


Default:	`0A(SGA), 0F(SGC)`
Example:	`SGA,01`	// Set advertisement RF output power to 1 dBm
	`SGC,FF`	// Set connection RF output power to -1 dBm
	`SGA,E7`	// Set advertisement RF output power to lowest
Response:	`AOK`	// Success
Response:	`Err`	// Syntax error or invalid parameter
Note: The PDS stores these parameters. The parameters are effective immediately. The baseband can re-assign the setting if the setting does not match the range from baseband. The set output power value in this command is Effective Isotropic Radiated Power (EIRP) of the module, in other words, RF power from the device (upto 12 dBm) + antenna gain (3dBi) antenna gain.
