system.cmd.aux_bus

Abbreviation

sy c x

Access

get/set

Description

Enables or disables the aux_bus which maps to the log bus, acting as an auxiliary command console.

If system.cmd.aux_bus is set to 1 then an additional command console is allocated to the log bus.

The following command sequence shows an example of using this variable. The data bus, UART0, is used in stream mode and the log bus, UART1, is used for receiving logs and sending commands. 

set bus.log_bus uart1
set bus.data_bus uart0
set system.cmd.aux_bus 1
set bus.mode stream
set wlan.ssid <network name>
set wlan.passkey <network password>
set wlan.auto_join.enabled 1
set tcp.client.auto_start 1
set tcp.client.remote_host test.zentri.com
set tcp.client.remote_port 50007
save
reboot

On rebooting, UART0 will send to, and receive data from, the remote TCP server test.zentri.com .

UART1 can be used to receive logs as well as send commands to Gecko OS.

Note that the $$$ break-in sequence can still be used to break in to command mode via UART0. See Serial Interface, Breaking out of Stream Mode .

Arguments

system.cmd.buffered

Abbreviation

sy c b

Access

get/set

Description

Flag to enable/disable buffering of certain command responses. This is intended for use when reading command output by machine. See Serial Interface, Command Protocol .

If enabled, a command's response is buffered and a stream handle along with the response size in bytes is returned.

The host must use the read command to retrieve the command's response data.

Note that if headers are enabled, the header is returned along with the stream handle and response size.

The following commands are buffered if the system.cmd.buffered flag is set:

Stream Type : CMD . See Networking and Security, Network Connections and Streams .

system.cmd.gpio

Abbreviation

sy c g

Access

get/set

Description

When configured, this GPIO is asserted HIGH AFTER Gecko OS issues a command response. It is cleared (i.e. set LOW) on the start of the next command.

Note : The system.cmd_gpio is triggered only for commands FROM the serial bus. Commands from other sources such as the remote terminal and REST API have no effect.

This makes sending commands to Gecko OS much easier:

With DMA, the processor has to do little work. The command TX and response RX can be done in the background. An external pin interrupt triggers when the command/response sequence is complete.

system.oob.gpio

Abbreviation

sy o g

Access

get/set

Description

The system.oob variables allow creation of an out-of-band interrupt (OOB) GPIO. This GPIO is asserted whenever one or more of the configured OOB events occurs. It is de-asserted when reading the OOB status register.

Note : OOB events are in most cases related to a corresponding special function GPIO variable. However, the OOB event can be configured without setting the corresponding special function GPIO. For example, the network.status_gpio OOB event can be triggered without setting the wlan.network.status_gpio variable.

Specify the OOB GPIO with the system.oob.gpio variable.

Specify the active level of the OOB GPIO with system.oob.gpio_level .

Specify the events that cause the OOB GPIO to be asserted with system.oob.event_mask .

Specify events that trigger the OOB GPIO only on the rising edge (i.e. when the event is asserted) with system.oob.rising_edge_mask .

Read the events that triggered an OOB interrupt from the system.oob.status variable.

Only one GPIO can be specified as the OOB GPIO. Determine the OOB GPIO by reading the gpio.usage variable or the system.oob.gpio variable.

Events are mapped to the event mask , rising edge mask and status mask as shown in the following table:

OOB Event Name Mask Value
ioconn.status_gpio 0x001
wlan.network.status_gpio 0x002
tcp.server.connected_gpio 0x004
tcp.server.data_gpio 0x008
udp.server.data_gpio 0x010
tcp.client.data_gpio (see tcp_client -g ) 0x020
udp.client.data_gpio (see udp_client -g ) 0x040
http.server.ws_connected_gpio 0x080
http.server.ws_data_gpio 0x100
websocket.client.data_gpio (see websocket_client ) 0x200
HTTP data ready (see http_get , http_post commands) 0x400

See Handling Multiple Clients with OOB Interrupts for details of use.

system.oob.rising_edge_mask

Abbreviation

sy o r

Access

get/set

Description

The mask of events which should trigger the OOB GPIO only on the rising edge (i.e. when an event is asserted). See system.oob.gpio .

If the mask is cleared, then the OOB GPIO is asserted on both rising and falling edges.

For instance, when the module connects, the network status event event is considered asserted. When the module disconnects, the event is considered de-asserted.

For event/mask mapping, see the system.oob.gpio event mask table .

Arguments

<hex mask> Mask is specified in the form 0xHH where H is a hexadecimal digit 0-F.

system.oob.status

Abbreviation

sy o s

Access

get

Description

The mask of triggered events. When an event is triggered, the OOB GPIO is asserted and the status mask is updated with the triggering event. Reading this variable returns a mask of events that caused the OOB gpio to be asserted.

Reading this variable de-asserts the OOB GPIO and clears the status mask.

For event/mask mapping, see the system.oob.gpio event mask table .

If enabled, the Kernel remains in DFU mode on OTA failure. The Kernel periodically re-attempts to OTA based on the system.safemode.console_timeout and system.safemode.sleep_timeout configuration. The Kernel remains in DFU mode mode until the OTA successfully completes or the dfu --exit command is issued.

Notes

This variable is used only for 'pull' DFU (i.e. direct OTA DFU with DMS).

system.security_key

Abbreviation

sy k

Access

set

Description

The system.security_key variable specifies an AES-128 encryption key. This is sometimes referred to as the user key, because the user can set the value of this key. This is distinct from the device key, a hidden key supplied with the Gecko OS device that the user cannot see or set.

The key is stored in a special section of the NVM.

The variable value cannot be read with the get command.

The following commands use this key for encrypting the file saved on flash and set the User Encrypted file flag:

When Gecko OS reads a file with the Encrypted flag set, for internal use (within the device MCU only), it automatically decrypts the file with the system.security_key .

For example, this may take place when Gecko OS:

To decrypt a file with the Encrypted flag set, use one of the following commands, supplying a <security key> argument matching the system.security_key :

To clear system.security_key , set value to none .
