CC2540 - Setting Tx Power Steps

Other Parts Discussed in Thread: CC2540

CC254x Champs,

I'm aware of two methods of setting the output power of the CC2540 : HCI_EXT_SetMaxDtmTxPowerCmd and HCI_EXT_SetTxPowerCmd.  These commands are both described in the TI_BLE_Vendor Specific_HCI_Guide.pdf which is available in the docs folder of the SDK install.

Both commands enable the Tx to be set to the same steps: -23, -6, 0, and 4 dbm (CC2540 only).  I'm curious if it is possible to set the Tx power to a power setting in between those listed. For example -2 dbm.

Thanks!
