Sets the maximum number of BLE attributes.

Note

  • Maximum number of BLE attributes is 124.

  • Bits 0 - 7 are used to set MAX_NBR_ATT_REC.

SL_SI91X_BLE_MAX_NBR_ATT_SERV#

#define SL_SI91X_BLE_MAX_NBR_ATT_SERV
Value:
(max_num_of_att_serv)

BLE number of GATT services.

Sets the maximum number of BLE GATT services.

Note

  • Maximum number of services is 10.

  • Bits 8 - 11 are used to set MAX_NBR_ATT_SERV.

SL_SI91X_BLE_MAX_NBR_PERIPHERALS#

#define SL_SI91X_BLE_MAX_NBR_PERIPHERALS
Value:
(max_num_of_peripherals)

BLE number of peripherals.

Sets the maximum number of BLE peripherals.

Note

  • Maximum number of BLE peripherals is 8.

  • Bits 12 - 15 are used to set MAX_NBR_PERIPHERALS.

SL_SI91X_BLE_PWR_INX#

#define SL_SI91X_BLE_PWR_INX
Value:
(power_index)

BLE Tx power index.

Sets the BLE Tx power index value.

  • Default value for BLE Tx Power Index is 31.

  • Range for the BLE Tx Power Index is 1 to 127 (0, 32 index is invalid).

    • 1 - 31: BLE - 0dBm Mode

    • 33 - 63: BLE - 10dBm Mode

    • 64 - 127: BLE - HP Mode

Note

  • Bits 16 - 23 are used to set PWR_INX.

SL_SI91X_BLE_PWR_SAVE_OPTIONS#

#define SL_SI91X_BLE_PWR_SAVE_OPTIONS
Value:
(duty_cycle)

BLE power save options.

Configures BLE power save options.

  • Bit 24: BLE_DUTY_CYCLING

  • Bit 25: BLR_DUTY_CYCLING

  • Bit 26: BLE_4X_PWR_SAVE_MODE

  • For BLE_DISABLE_DUTY_CYCLING, bits 24-26 are set to zero.

Note

  • This feature is not supported in the current release.

SL_SI91X_BLE_MAX_NBR_CENTRALS#

#define SL_SI91X_BLE_MAX_NBR_CENTRALS
Value:
(max_num_of_centrals)

Number of Centrals.

Sets the maximum number of BLE Central devices.

Note

  • Maximum number of BLE Centrals is 2.

  • Bits 27 - 28 are used to set BLE_PWR_INX.

SL_SI91X_BLE_GATT_ASYNC_ENABLE#

#define SL_SI91X_BLE_GATT_ASYNC_ENABLE
Value:
BIT(29)

GATT ASYNC BIT.

Enables asynchronous GATT operations.

Note

  • Default is disabled. When enabled, the response structure will be filled in the Event, which will come later, not in sync with the response for the query command.
