Function Documentation#

sl_bt_system_hello#

sl_status_t sl_bt_system_hello ()

Verify whether the communication between the host and the device is functional.

NOTE: This command is available even if the Bluetooth stack has not been started. See sl_bt_system_start_bluetooth for description of how the Bluetooth stack is started.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_start_bluetooth#

sl_status_t sl_bt_system_start_bluetooth ()

If the Bluetooth on-demand start component is not included in the application build, the Bluetooth stack is automatically started when the device boots up. In this configuration, the on-demand start command is not available and the command returns the error SL_STATUS_NOT_AVAILABLE.

When the Bluetooth on-demand start component is included in the application build, this command is used by the application to request starting the Bluetooth stack when the application needs it. If the command returns a success result, the stack starts to asynchronously allocate the resources and configure the Bluetooth stack based on the configuration passed at initialization time.

The Bluetooth stack cannot be restarted while it's still stopping after issuing the command sl_bt_system_stop_bluetooth. If sl_bt_system_start_bluetooth is called when stopping is still on-going the command returns the error SL_STATUS_INVALID_STATE. The application must wait for the sl_bt_evt_system_stopped event before attempting to restart the stack.

Successful start of the stack is indicated by the sl_bt_evt_system_boot event. The configured classes and Bluetooth stack features are available after the application has received the sl_bt_evt_system_boot event. If starting the Bluetooth stack fails, the error is indicated to the application with the sl_bt_evt_system_error event.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

Events

  • sl_bt_evt_system_boot - Triggered when the Bluetooth stack has succesfully started and is ready to accept commands from the application

  • sl_bt_evt_system_error - Triggered if the command to start the Bluetooth stack was accepted but the asynchronous starting of the stack has failed

sl_bt_system_stop_bluetooth#

sl_status_t sl_bt_system_stop_bluetooth ()

If the Bluetooth on-demand start component is not included in the application build, the Bluetooth stack is automatically started when the device boots up. In this configuration, the stop command is not available and the command returns the error SL_STATUS_NOT_AVAILABLE.

When the Bluetooth on-demand start component is included in the application build, this command is used by the application to stop the Bluetooth stack when the application no longer needs it. This command gracefully restores Bluetooth to an idle state by disconnecting any active connections and stopping any on-going advertising and scanning. Any resources that were allocated when the stack was started are freed when the stack has finished stopping. After this command, the BGAPI classes other than System become unavailable.

Stopping the Bluetooth stack with this command is asynchronous and the completion is indicated by the sl_bt_evt_system_stopped event. The application can use the command sl_bt_system_start_bluetooth to restart the stack any time after it has received the sl_bt_evt_system_stopped event. If the application needs to stop the Bluetooth stack immediately, use the command sl_bt_system_forcefully_stop_bluetooth. That command can also be used to immediately complete the asynchronous stopping if the command sl_bt_system_stop_bluetooth has not completed in expected time period.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_forcefully_stop_bluetooth#

sl_status_t sl_bt_system_forcefully_stop_bluetooth ()

If the Bluetooth on-demand start component is not included in the application build, the Bluetooth stack is automatically started when the device boots up. In this configuration, the stop command is not available and the command returns the error SL_STATUS_NOT_AVAILABLE.

When the Bluetooth on-demand start component is included in the application build, this command is used by the application to forcefully stop the Bluetooth stack when the application no longer needs it. This command immediately stops all active Bluetooth operations such as advertising, scanning, and connections. Active connections are forcefully closed without performing the ACL Termination procedure. This can result in the observation of connection loss or supervision timeout on the remote device. Only use this command for special cases, for example, when stopping Bluetooth with sl_bt_system_stop_bluetooth did not complete in expected time period.

Stopping the Bluetooth stack with this command is immediate and it directly triggers the sl_bt_evt_system_stopped event. Any resources that were allocated when the stack was started are freed. After this command, the BGAPI classes other than System become unavailable. The application can use the command sl_bt_system_start_bluetooth to continue using Bluetooth later.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_reset#

void sl_bt_system_reset (uint8_t dfu)
Parameters
[in]dfu

Enum sl_bt_system_boot_mode_t. Boot mode. Values:

  • sl_bt_system_boot_mode_normal (0x0): Boot to normal mode

  • sl_bt_system_boot_mode_uart_dfu (0x1): Boot to UART DFU mode

  • sl_bt_system_boot_mode_ota_dfu (0x2): Boot to OTA DFU mode

This parameter is ignored on EFR series 2 devices.

Reset the system. This command does not have a response.

On EFR series 1 devices, this command boots into the given mode and triggers one of the boot events (normal reset or boot to DFU mode) depending on the given boot mode.

On EFR series 2 devices, the dfu parameter is ignored and this command always boots the user application. To boot into a DFU mode on series 2, use the Bootloader API bootloader_rebootAndInstall.

NOTE: This command is available even if the Bluetooth stack has not been started. See sl_bt_system_start_bluetooth for description of how the Bluetooth stack is started.

sl_bt_system_halt#

sl_status_t sl_bt_system_halt (uint8_t halt)
Parameters
[in]halt

Values:

  • 1: halt

  • 0: resume

Force radio to idle state and allow device to sleep. Advertising, scanning, connections, and software timers are halted by this command. Halted operations resume after calling this command with parameter 0. Connections stay alive if the system is resumed before connection supervision timeout.

Use this command only for a short time period (maximum few seconds). Although it halts Bluetooth activity, all tasks and operations still exist inside the stack with their own concepts of time. Halting the system for a long time period may have negative consequences on stack's internal states.

NOTE: The software timer is also halted. Hardware interrupts are the only way to wake up from energy mode 2 when the system is halted.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_set_tx_power#

sl_status_t sl_bt_system_set_tx_power (int16_t min_power, int16_t max_power, int16_t * set_min, int16_t * set_max)
Parameters
[in]min_power

Minimum radiated TX power. Unit: 0.1 dBm. For example, the value 10 means 1 dBm.

[in]max_power

Maximum radiated TX power. Unit: 0.1 dBm. For example, the value 10 means 1 dBm.

[out]set_min

The selected minimum radiated TX power. Unit: 0.1 dBm

[out]set_max

The selected maximum radiated TX power. Unit: 0.1 dBm

Set the global minimum and maximum radiated TX power levels for Bluetooth. This returns selected power levels that are radiated from the antenna at TX. The transmitter power at antenna pin will apply the RF TX path gain to match this setting. RF TX path gain can be set in the Bluetooth configuration. If the GATT server contains a TX power service, the TX Power Level attribute will be updated with the selected maximum power level.

A selected power level may be different than the requested value because of Bluetooth feature restrictions or the device's radio characteristics. For Bluetooth connections, the maximum radiated TX power is limited to 10 dBm if Adaptive Frequency Hopping (AFH) is not enabled.

The minimum TX power setting is used by LE power control. It has no effect in Bluetooth stack if the LE power control feature is not enabled. However, the application may still use this setting for other purposes, e.g., setting the minimum TX power for DTM transmitter test.

The minimum and maximum radiated TX power levels can also be configured in the Bluetooth configuration and passed into the Bluetooth stack initialization. By default, the minimum radiated TX power level is configured to -3 dBm and the maximum radiated TX power level to 8 dBm.

NOTE: Do not use this command while advertising or scanning. Furthermore, the stack does not allow setting TX powers during connections.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_set_identity_address#

sl_status_t sl_bt_system_set_identity_address (bd_addr address, uint8_t type)
Parameters
[in]address

Bluetooth identity address in little endian format

[in]type

Enum sl_bt_gap_address_type_t. Identity address type. Values:

  • sl_bt_gap_public_address (0x0): Public device address

  • sl_bt_gap_static_address (0x1): Static device address

Store the device's Bluetooth identity address in persistent storage using NVM keys. The address can be a public device address or a static device address. The stack returns an error if the static device address does not conform to the Bluetooth specification.

The new address will be effective in the next system reboot. The stack will use the address in the NVM keys when present. Otherwise, it uses the default Bluetooth public device address which is programmed at production.

The stack treats 00:00:00:00:00:00 and ff:ff:ff:ff:ff:ff as invalid addresses. Therefore, passing one of them into this command will cause the stack to delete the NVM keys and use the default address in the next system reboot.

Note: Because the NVM keys are located in flash and flash wearing can occur, avoid calling this command regularly.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

Parameters
[in]data_len

Length of data in data

[in]data

Data to write

Write data into the system data buffer. Data will be appended to the end of existing data.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_get_counters#

sl_status_t sl_bt_system_get_counters (uint8_t reset, uint16_t * tx_packets, uint16_t * rx_packets, uint16_t * crc_errors, uint16_t * failures)
Parameters
[in]reset

Reset counters if the parameter value is not zero.

[out]tx_packets

The number of successfully transmitted packets

[out]rx_packets

The number of successfully received packets

[out]crc_errors

The number of received packets with CRC errors

[out]failures

The number of radio failures, such as aborted TX/RX packets, scheduling failures, and so on.

Get packet and error counters. Passing a non-zero value also resets counters.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.

sl_bt_system_set_lazy_soft_timer#

sl_status_t sl_bt_system_set_lazy_soft_timer (uint32_t time, uint32_t slack, uint8_t handle, uint8_t single_shot)
Parameters
[in]time

An interval between how often to send events in hardware clock ticks (1 second is equal to 32768 ticks).

The smallest interval value supported is 328, which is around 10 milliseconds. Any parameters between 0 and 328 will be rounded up to 328. The maximum value is 2147483647, which corresponds to about 18.2 hours.

If time is 0, removes the scheduled timer with the same handle.

[in]slack

Slack time in hardware clock ticks

[in]handle

Timer handle to use, which is returned in timeout event

[in]single_shot

Timer mode. Values:

  • 0: false (timer is repeating)

  • 1: true (timer runs only once)

Deprecated . Use the sleeptimer component (in platform services category) for timers. Because the sleeptimer does not support a timer with slack yet, the Bluetooth stack will continue to support this command until another component provides the functionality.

Start a software timer with slack. The slack parameter allows the stack to optimize wakeups and save power. The timer event is triggered between time and time + slack.

Multiple concurrent timers can be running simultaneously. 256 unique timer handles (IDs) are available. The maximum number of concurrent timers is configurable at device initialization. Up to 16 concurrent timers can be configured. The default configuration is 4. As the RAM for storing timer data is pre-allocated at initialization, an application should not configure the amount more than it needs for minimizing RAM usage.

Returns

  • SL_STATUS_OK if successful. Error code otherwise.
