System (system)#

The commands and events in this class can be used to access and query the local device.

Commands#

system_get_bt_address#

This command can be used to read the Bluetooth public address used by the device.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_get_bt_address_rsp_t *gecko_cmd_system_get_bt_address();

/* Response id */
gecko_rsp_system_get_bt_address_id

/* Response structure */
struct gecko_msg_system_get_bt_address_rsp_t
{
  bd_addr address
}

system_get_counters#

Get packet and error counters

Command#

Response#

struct gecko_msg_system_get_counters_rsp_t
{
  uint16 result,
  uint16 tx_packets,
  uint16 rx_packets,
  uint16 crc_errors,

}

system_get_random_data#

This command can be used to get random data up to 16 bytes.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_get_random_data_rsp_t *gecko_cmd_system_get_random_data(uint8 length);

/* Response id */
gecko_rsp_system_get_random_data_id

/* Response structure */
struct gecko_msg_system_get_random_data_rsp_t
{
  uint16 result,
  uint8array data
}

system_halt#

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

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

Command#

Response#

API#

/* Function */
struct gecko_msg_system_halt_rsp_t *gecko_cmd_system_halt(uint8 halt);

/* Response id */
gecko_rsp_system_halt_id

/* Response structure */
struct gecko_msg_system_halt_rsp_t
{
  uint16 result
}

system_hello#

This command does not trigger any event but the response to the command is used to verify that communication between the host and the device is working.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_hello_rsp_t *gecko_cmd_system_hello();

/* Response id */
gecko_rsp_system_hello_id

/* Response structure */
struct gecko_msg_system_hello_rsp_t
{
  uint16 result
}

system_reset#

This command can be used to reset the system. It does not have a response, but it triggers one of the boot events (normal reset or boot to DFU mode) depending on the selected boot mode.

Command#

Command does not have response#

API#

/* Function */
void *gecko_cmd_system_reset(uint8 dfu);

/* Command does not have response */

Events generated#

system_set_bt_address#

This command can be used to set the Bluetooth public address used by the device. A valid address set with this command overrides the default Bluetooth public address programmed at production, and it will be effective in the next system reboot. The stack treats 00:00:00:00:00:00 and ff:ff:ff:ff:ff:ff as invalid addresses. Thus passing one of them into this command will cause the stack to use the default address in the next system reboot.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_set_bt_address_rsp_t *gecko_cmd_system_set_bt_address(bd_addr address);

/* Response id */
gecko_rsp_system_set_bt_address_id

/* Response structure */
struct gecko_msg_system_set_bt_address_rsp_t
{
  uint16 result
}

system_set_device_name#

This command can be used to set the device name. Currently it is possible to set the name which will be used during the OTA update. The name will be stored in persistent storage. If the OTA device name is also set in gecko configuration, the name stored in persistent storage is overwritten with the name in gecko configuration during device boot.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_set_device_name_rsp_t *gecko_cmd_system_set_device_name(uint8 type, uint8 name_len, const uint8 *name_data);

/* Response id */
gecko_rsp_system_set_device_name_id

/* Response structure */
struct gecko_msg_system_set_device_name_rsp_t
{
  uint16 result
}

system_set_tx_power#

This command can be used to set the TX power. It returns the power that was set. If the GATT server contains a Tx Power service, the Tx Power Level attribute of the service will be updated accordingly.

NOTE: This command should not be used while advertising, scanning or during connection.

Command#

Response#

API#

/* Function */
struct gecko_msg_system_set_tx_power_rsp_t *gecko_cmd_system_set_tx_power(int16 power);

/* Response id */
gecko_rsp_system_set_tx_power_id

/* Response structure */
struct gecko_msg_system_set_tx_power_rsp_t
{
  int16 set_power
}

Events#

system_boot#

This event indicates the device has started and the radio is ready. This even carries the firmware build number and other SW and HW identification codes.

Event#

API#

/* event id*/
gecko_evt_system_boot_id

/* event structure*/
struct gecko_msg_system_boot_evt_t
{
  uint16 major,
  uint16 minor,
  uint16 patch,
  uint16 build,
  uint32 bootloader,
  uint16 hw,
  uint32 hash
}

system_external_signal#

This event indicates external signals have been received. External signals are generated from native application.

Event#

API#

/* event id*/
gecko_evt_system_external_signal_id

/* event structure*/
struct gecko_msg_system_external_signal_evt_t
{
  uint32 extsignals
}

system_awake#

This event indicates that the device has woken up from sleep mode.

NOTE: Stack does not generate this event by itself as sleep and wakeup are managed in applications. If this event is needed, the application should call function gecko_send_system_awake() to signal stack to send this event.

Event#

API#

/* event id*/
gecko_evt_system_awake_id

/* event structure*/
struct gecko_msg_system_awake_evt_t
{
}

system_hardware_error#

This event indicates that hardware related errors occurred.

Event#

API#

/* event id*/
gecko_evt_system_hardware_error_id

/* event structure*/
struct gecko_msg_system_hardware_error_evt_t
{
  uint16 status
}

system_error#

This event indicates errors.

Event#

API#

/* event id*/
gecko_evt_system_error_id

/* event structure*/
struct gecko_msg_system_error_evt_t
{
  uint16 reason,
  uint8array data
}
