(New) - is mark for new interpretation of this status code, may be repeated codes, because we have different interpretation from different sources of some codes
| Status | Status Hex | Description | Explanation |
|---|---|---|---|
| 0 | 0x00 | BLE_HCI_STATUS_CODE_SUCCESS | Everything ok!:) |
| 1 | 0x01 | BLE_HCI_STATUS_CODE_UNKNOWN_BTLE_COMMAND | |
| 1 | 0x01 | CONNECTION_PRIORITY_HIGH | (New)Connection parameter update - Request a high priority, low latency connection. An application should only request high priority connection parameters to transfer large amounts of data over LE quickly. Once the transfer is complete, the application should request BluetoothGatt#CONNECTION_PRIORITY_BALANCED connection parameters to reduce energy use. |
| 2 | 0x02 | BLE_HCI_STATUS_CODE_UNKNOWN_CONNECTION_IDENTIFIER | |
| 2 | 0x02 | CONNECTION_PRIORITY_LOW_POWER | (New)Connection parameter update - Request low power, reduced data rate connection parameters. |
| 3 | 0x03 | GATT_WRITE_NOT_PERMITTED | GATT write operation is not permitted |
| 5 | 0x05 | BLE_HCI_AUTHENTICATION_FAILURE | Insufficient authentication for a given operation |
| 6 | 0x06 | BLE_HCI_STATUS_CODE_PIN_OR_KEY_MISSING | |
| 6 | 0x06 | GATT_REQUEST_NOT_SUPPORTED | The given request is not supported |
| 7 | 0x07 | BLE_HCI_MEMORY_CAPACITY_EXCEEDED | |
| 7 | 0x07 | GATT_INVALID_OFFSET | A read or write operation was requested with an invalid offset |
| 8 | 0x08 | BLE_HCI_CONNECTION_TIMEOUT | Could not establish a connection in specified period. Maybe device is currently connected to something else? |
| 8 | 0x08 | GATT_INSUFFICIENT_AUTHORIZATION | Insufficient authorization for a given operation |
| 12 | 0x0C | BLE_HCI_STATUS_CODE_COMMAND_DISALLOWED | |
| 13 | 0xD | GATT_INVALID_ATTRIBUTE_LENGTH | A write operation exceeds the maximum length of the attribute |
| 15 | 0xF | GATT_INSUFFICIENT_ENCRYPTION | Insufficient encryption for a given operation |
| 18 | 0x12 | BLE_HCI_STATUS_CODE_INVALID_BTLE_COMMAND_PARAMETERS | |
| 19 | 0x13 | BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION | Remote device has forced a disconnect. |
