## Detailed Description

## Function Documentation

## ◆ ble_activity_end_notify_cb_register()

void ble_activity_end_notify_cb_register | ( | void(*)(ble_gap_actv_role_t e_role, uint8_t index) | callback | ) |

Register BLE activity end notification callback function.

Parameters

  [in] | callback | function pointer of BLE activity end notification function.

Note
  param[in] of callback: e_role - the role of activity,gap_activity_role_t for possible roles. param[in] of callback: index - The index parameter is interpreted by role. If role is GAP_ACTIVITY_ROLE_ADV, it's the index of Advertising. If role is GAP_ACTIVITY_ROLE_CON, it's the index of Connection. For all other roles, it should be ignored. Callback will be called by BLE ISR when the BLE activity ends every time. It should be realized as simlpe as you can. You'd better to define it in the RAM space It's not suitable for ISO activities.

## ◆ ble_activity_start_notify_cb_register()

void ble_activity_start_notify_cb_register | ( | void(*)(ble_gap_actv_role_t e_role, uint8_t index) | callback | ) |

Register BLE activity start notification callback function.

Parameters

  [in] | callback | function pointer of BLE activity start notification function.

Note
  param[in] of callback: e_role - the role of activity, gap_activity_role_t for possible roles. param[in] of callback: index - The index parameter is interpreted by role. If role is GAP_ACTIVITY_ROLE_ADV, it's the index of Advertising. If role is GAP_ACTIVITY_ROLE_CON, it's the index of Connection. For all other roles, it should be ignored. Callback will be called by BLE ISR when the BLE activity starts every time. It should be realized as simlpe as you can. Notice: You must define the start callback in the RAM space to avoid hardfault. It's not suitable for ISO activities.

## ◆ ble_hci_uart_register()

void ble_hci_uart_register | ( | uint8_t | id,
|  | hci_uart_call_t * | api
| ) |  |

Register UART instance for HCI.

Parameters

  [in] | id | Instance index.
  [in] | api | Pointer to the struct of function pointers for HCI UART.

## ◆ ble_idle_time_notify_cb_register()

void ble_idle_time_notify_cb_register | ( | void(*)(uint32_t hs) | callback | ) |

Register BLE idle time notification callback function.

Parameters

  [in] | callback | function pointer of BLE idle time notification function.

Note
  param[in] of callback: hs - the idle time of BLE in half slot (312.5μs). Callback will be called by BLE ISR to notify the rest idle time if there are some BLE activities. It should be realized as simlpe as you can. It's not suitable for ISO activities.

## ◆ ble_rf_match_circuit_get()

ble_rf_match_circuit_t ble_rf_match_circuit_get | ( | void |  | ) |

Get the resistance value of the RF match circuit (unit: ohm).

Returns
  The resistance value (ohm) of the RF match circuit according to the board (ohm). BLE_RF_MATCH_CIRCUIT_25OHM: 25 ohm. BLE_RF_MATCH_CIRCUIT_100OHM: 100 ohm. Others: invalid.

## ◆ ble_rf_match_circuit_set()

void ble_rf_match_circuit_set | ( | ble_rf_match_circuit_t | e_ohm | ) |

Set the resistance value of the RF match circuit (unit: ohm).

Note
  This function should be called before BLE stack init.

Parameters

  [in] | e_ohm | The resistance value (ohm) of the RF match circuit according to the board. BLE_RF_MATCH_CIRCUIT_25OHM: 25 ohm. BLE_RF_MATCH_CIRCUIT_100OHM: 100 ohm. Others: invalid.

## ◆ ble_rf_tx_mode_get()

ble_rf_tx_mode_t ble_rf_tx_mode_get | ( | void |  | ) |

Get the RF TX mode of LP or ULP.

Returns
  BLE_RF_TX_MODE_LP_MODE: LP Mode. BLE_RF_TX_MODE_ULP_MODE: ULP Mode. Others: Fail.

## ◆ ble_rf_tx_mode_set()

uint8_t ble_rf_tx_mode_set | ( | ble_rf_tx_mode_t | e_rf_tx_mode | ) |

Change the RF TX mode of LP or ULP.

Parameters
