BLE Feature Bitmap#
This section provides a reference to the Bluetooth Low Energy (BLE) feature bitmap in the boot configuration.
Macros#
BLE number of attributes,.
BLE number of GATT services.
BLE number of peripherals.
BLE Tx power index.
BLE powersave options Bit 24 for BLE_DUTY_CYCLING Bit 25 for BLR_DUTY_CYCLING Bit 26 for BLE_4X_PWR_SAVE_MODE For BLE_DISABLE_DUTY_CYCLING, BITs 24-26 are set to be zero.
Number of Centrals.
GATT SYNC BIT.
0 for 9113 compatible; 1 for enabling 9116 BLE-compatible features.
Extention valid to use Extended custom feature bitmap.

SL_SI91X_BLE_PWR_INX#
#define SL_SI91X_BLE_PWR_INXValue:
(power_index)

Note
Give 31 as BLE TX power index (e.g.,: 31<<16) This variable is used to select the BLE TX power index value. The following are the possible values. Default Value for BLE Tx Power Index is 31 Range for the BLE Tx Power Index is 1 to 75 (0, 32 index is invalid) 1 - 31 BLE -0DBM Mode 33 - 63 BLE- 10DBM Mode 64- 75 BLE - HP Mode.
Bits 16 - 23 are used to set PWR_INX
