Command Structure¶

The common options of the call and dispatch commands are documented here. The specific command structure is shown below.

tinkerforge call master-brick [<option>..] <uid> <function> [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The call command is used to call a function of the Master Brick. It can take several options:

• --help shows help for the specific call command and exits
• --list-functions shows a list of known functions of the Master Brick and exits

tinkerforge dispatch master-brick [<option>..] <uid> <callback>¶

Parameters:	<uid> – Type: String <callback> – Type: String

The dispatch command is used to dispatch a callback of the Master Brick. It can take several options:

• --help shows help for the specific dispatch command and exits
• --list-callbacks shows a list of known callbacks of the Master Brick and exits

tinkerforge call master-brick <uid> <function> [<option>..] [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The <function> to be called can take different options depending of its kind. All functions can take the following options:

• --help shows help for the specific function and exits

Getter functions can take the following options:

• --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Setter functions can take the following options:

• --expect-response requests response and waits for it

The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

tinkerforge call master-brick <uid> get-rs485-error-log¶

Output:	crc-error – Type: Int, Range: [0 to 216 - 1]

Returns CRC error counts of the RS485 communication. If this counter starts rising, it is likely that the distance between the RS485 nodes is too big or there is some kind of interference.

tinkerforge call master-brick <uid> set-rs485-configuration <speed> <parity> <stopbits>¶

Parameters:	<speed> – Type: Int, Unit: 1 Bd, Range: [0 to 232 - 1] <parity> – Type: Char, Range: See symbols <stopbits> – Type: Int, Range: [1 to 2]
Output:	no output

Sets the configuration of the RS485 Extension. The Master Brick will try to match the given baud rate as exactly as possible. The maximum recommended baud rate is 2000000 (2MBd). Possible values for parity are 'n' (none), 'e' (even) and 'o' (odd).

If your RS485 is unstable (lost messages etc.), the first thing you should try is to decrease the speed. On very large bus (e.g. 1km), you probably should use a value in the range of 100000 (100kBd).

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after configuration.

The following symbols are available for this function:

For <parity>:

• rs485-parity-none = n
• rs485-parity-even = e
• rs485-parity-odd = o

tinkerforge call master-brick <uid> get-rs485-configuration¶

Value	Description
0	DHCP
1	Static IP
2	Access Point: DHCP
3	Access Point: Static IP
4	Ad Hoc: DHCP
5	Ad Hoc: Static IP

If you set connection to one of the static IP options then you have to supply ip, subnet_mask and gateway as an array of size 4 (first element of the array is the least significant byte of the address). If connection is set to one of the DHCP options then ip, subnet_mask and gateway are ignored, you can set them to 0.

The last parameter is the port that your program will connect to.

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after configuration.

It is recommended to use the Brick Viewer to set the WIFI configuration.

The following symbols are available for this function:

For <connection>:

• wifi-connection-dhcp = 0
• wifi-connection-static-ip = 1
• wifi-connection-access-point-dhcp = 2
• wifi-connection-access-point-static-ip = 3

Parameters:	<encryption> – Type: Int, Range: See symbols <key> – Type: String, Length: up to 50 <key-index> – Type: Int, Range: [1 to 4] <eap-options> – Type: Int, Range: See symbols <ca-certificate-length> – Type: Int, Unit: 1 B, Range: [0 to 1312] <client-certificate-length> – Type: Int, Unit: 1 B, Range: [0 to 1312] <private-key-length> – Type: Int, Unit: 1 B, Range: [0 to 4320]
Output:	no output

Sets the encryption of the WIFI Extension. The first parameter is the type of the encryption. Possible values are:

Value	Description
0	WPA/WPA2
1	WPA Enterprise (EAP-FAST, EAP-TLS, EAP-TTLS, PEAP)
2	WEP
3	No Encryption

The key has a max length of 50 characters and is used if encryption is set to 0 or 2 (WPA/WPA2 or WEP). Otherwise the value is ignored.

For WPA/WPA2 the key has to be at least 8 characters long. If you want to set a key with more than 50 characters, see set-long-wifi-key.

For WEP the key has to be either 10 or 26 hexadecimal digits long. It is possible to set the WEP key_index (1-4). If you don't know your key_index, it is likely 1.

If you choose WPA Enterprise as encryption, you have to set eap_options and the length of the certificates (for other encryption types these parameters are ignored). The certificates themselves can be set with set-wifi-certificate. eap_options consist of the outer authentication (bits 1-2), inner authentication (bit 3) and certificate type (bits 4-5):

Option	Bits	Description
outer authentication	1-2	0=EAP-FAST, 1=EAP-TLS, 2=EAP-TTLS, 3=EAP-PEAP
inner authentication	3	0=EAP-MSCHAP, 1=EAP-GTC
certificate type	4-5	0=CA Certificate, 1=Client Certificate, 2=Private Key

Example for EAP-TTLS + EAP-GTC + Private Key: option = 2 | (1 << 2) | (2 << 3).

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after configuration.

It is recommended to use the Brick Viewer to set the Wi-Fi encryption.

tinkerforge call master-brick <uid> refresh-wifi-status¶

Output:	no output

Refreshes the Wi-Fi status (see get-wifi-status). To read the status of the Wi-Fi module, the Master Brick has to change from data mode to command mode and back. This transaction and the readout itself is unfortunately time consuming. This means, that it might take some ms until the stack with attached WIFI Extension reacts again after this function is called.

tinkerforge call master-brick <uid> set-wifi-certificate <index> <data> <data-length>¶

Parameters:	<index> – Type: Int, Range: [0 to 1311, 10000 to 11311, 20000 to 24319, 65534 to 216 - 1] <data> – Type: Int Array, Length: 32, Range: [0 to 255] <data-length> – Type: Int, Unit: 1 B, Range: [0 to 32]
Output:	no output

This function is used to set the certificate as well as password and username for WPA Enterprise. To set the username use index 0xFFFF, to set the password use index 0xFFFE. The max length of username and password is 32.

The certificate is written in chunks of size 32 and the index is used as the index of the chunk. data_length should nearly always be 32. Only the last chunk can have a length that is not equal to 32.

The starting index of the CA Certificate is 0, of the Client Certificate 10000 and for the Private Key 20000. Maximum sizes are 1312, 1312 and 4320 byte respectively.

The values are stored in the EEPROM and only applied on startup. That means you have to restart the Master Brick after uploading the certificate.

It is recommended to use the Brick Viewer to set the certificate, username and password.

tinkerforge call master-brick <uid> get-wifi-certificate <index>¶

Parameters:	<index> – Type: Int, Range: [0 to 1311, 10000 to 11311, 20000 to 24319, 65534 to 216 - 1]
Output:	data – Type: Int Array, Length: 32, Range: [0 to 255] data-length – Type: Int, Range: [0 to 32]

Returns the certificate for a given index as set by set-wifi-certificate.

tinkerforge call master-brick <uid> set-wifi-power-mode <mode>¶

Parameters:	<mode> – Type: Int, Range: See symbols, Default: 0
Output:	no output

Sets the power mode of the WIFI Extension. Possible modes are:

Mode	Description
0	Full Speed (high power consumption, high throughput)
1	Low Power (low power consumption, low throughput)

The following symbols are available for this function:

For <mode>:

• wifi-power-mode-full-speed = 0
• wifi-power-mode-low-power = 1

tinkerforge call master-brick <uid> get-wifi-power-mode¶

Output:	mode – Type: Int, Range: See symbols, Default: 0

Returns the power mode as set by set-wifi-power-mode.

The following symbols are available for this function:

tinkerforge call master-brick <uid> get-wifi-buffer-info¶

Output:	overflow – Type: Int, Range: [0 to 232 - 1] low-watermark – Type: Int, Unit: 1 B, Range: [0 to 1500] used – Type: Int, Unit: 1 B, Range: [0 to 1500]

Returns informations about the Wi-Fi receive buffer. The Wi-Fi receive buffer has a max size of 1500 byte and if data is transfered too fast, it might overflow.

The return values are the number of overflows, the low watermark (i.e. the smallest number of bytes that were free in the buffer) and the bytes that are currently used.

You should always try to keep the buffer empty, otherwise you will have a permanent latency. A good rule of thumb is, that you can transfer 1000 messages per second without problems.

Try to not send more then 50 messages at a time without any kind of break between them.

If the root_ip parameter is set to all zero then root_subnet_mask and root_gateway parameters are also set to all zero and DHCP is used for IP address configuration. Otherwise those three parameters can be used to configure a static IP address. The default configuration is DHCP.

If the router_bssid parameter is set to all zero then the information is taken from Wi-Fi scan when connecting the SSID as set by set-wifi2-mesh-router-ssid. This only works if the the SSID is not hidden. In case the router has hidden SSID this parameter must be specified, otherwise the node will not be able to reach the mesh router.

The group_id and the group_ssid_prefix parameters identifies a particular mesh network and nodes configured with same group_id and the group_ssid_prefix are considered to be in the same mesh network.

The gateway_ip and the gateway_port parameters specifies the location of the brickd that supports mesh feature.

To apply configuration changes to the WIFI Extension 2.0 the save-wifi2-configuration function has to be called and the Master Brick has to be restarted afterwards.

It is recommended to use the Brick Viewer to configure the WIFI Extension 2.0.

tinkerforge call master-brick <uid> set-spitfp-baudrate-config <enable-dynamic-baudrate> <minimum-dynamic-baudrate>¶

Parameters:	<enable-dynamic-baudrate> – Type: Bool, Default: true <minimum-dynamic-baudrate> – Type: Int, Unit: 1 Bd, Range: [400000 to 2000000], Default: 400000
Output:	no output

The SPITF protocol can be used with a dynamic baudrate. If the dynamic baudrate is enabled, the Brick will try to adapt the baudrate for the communication between Bricks and Bricklets according to the amount of data that is transferred.

The baudrate will be increased exponentially if lots of data is sent/received and decreased linearly if little data is sent/received.

This lowers the baudrate in applications where little data is transferred (e.g. a weather station) and increases the robustness. If there is lots of data to transfer (e.g. Thermal Imaging Bricklet) it automatically increases the baudrate as needed.

In cases where some data has to transferred as fast as possible every few seconds (e.g. RS485 Bricklet with a high baudrate but small payload) you may want to turn the dynamic baudrate off to get the highest possible performance.

The maximum value of the baudrate can be set per port with the function set-spitfp-baudrate. If the dynamic baudrate is disabled, the baudrate as set by set-spitfp-baudrate will be used statically.

New in version 2.4.6 (Firmware).

tinkerforge call master-brick <uid> get-spitfp-baudrate-config¶

Output:	enable-dynamic-baudrate – Type: Bool, Default: true minimum-dynamic-baudrate – Type: Int, Unit: 1 Bd, Range: [400000 to 2000000], Default: 400000

Parameters:	<communication-method> – Type: Int, Range: See symbols
Output:	timeout-count – Type: Int, Range: [0 to 232 - 1]

Returns the timeout count for the different communication methods.

The methods 0-2 are available for all Bricks, 3-7 only for Master Bricks.

This function is mostly used for debugging during development, in normal operation the counters should nearly always stay at 0.

The following symbols are available for this function:

For <communication-method>:

• communication-method-none = 0

Output:	no output

Sets the baudrate for a specific Bricklet port.

If you want to increase the throughput of Bricklets you can increase the baudrate. If you get a high error count because of high interference (see get-spitfp-error-count) you can decrease the baudrate.

If the dynamic baudrate feature is enabled, the baudrate set by this function corresponds to the maximum baudrate (see set-spitfp-baudrate-config).

Regulatory testing is done with the default baudrate. If CE compatibility or similar is necessary in your applications we recommend to not change the baudrate.
