BlueCore4-ROM CSP firmware maintains the transmit power to be within the Bluetooth specification
v2.0+EDR limits.
Measurement made using a PSKEY_LC_MAX_TX_POWER setting corresponds to a
PSKEY_LC_POWER_TABLE power table entry of 63.
Class 2 RF transmit power range, Bluetooth specification v2.0+EDR.
To some extent these parameters are dependent on the matching circuit used, and its behaviour over
temperature. Therefore these parameters may be beyond CSRâs direct control.
Resolution guaranteed over the range -5dB to -25dB relative to maximum power for Tx Level >20.
Measured at F0 = 2441MHz.
Up to three exceptions are allowed in v2.0+EDR of the Bluetooth specification. BlueCore4-ROM CSP is
guaranteed to meet the ACP performance as specified by the Bluetooth specification v2.0+EDR.
