Sets up to 254 slave addresses. 0 has a special meaning, it is used as list terminator and not allowed as normal slave address. The address numeration (via num parameter) has to be used ascending from 0. For example: If you use the Chibi Extension in Master mode (i.e. the stack has an USB connection) and you want to talk to three other Chibi stacks with the slave addresses 17, 23, and 42, you should call with (0, 17), (1, 23), (2, 42) and (3, 0). The last call with (3, 0) is a list terminator and indicates that the Chibi slave address list contains 3 addresses in this case.

Function BrickMaster.GetRS485ErrorLog() As Integer¶

Returns:	crcError – Type: Integer, 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.

Sub BrickMaster.SetRS485Configuration(ByVal speed As Long, ByVal parity As Char, ByVal stopbits As Byte)¶

Parameters:	speed – Type: Long, Unit: 1 Bd, Range: [0 to 232 - 1] parity – Type: Char, Range: See constants stopbits – Type: Byte, Range: [1 to 2]

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 constants are available for this function:

For parity:

• BrickMaster.RS485_PARITY_NONE = "n"C
• BrickMaster.RS485_PARITY_EVEN = "e"C

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.

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 SetLongWifiKey().

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 SetWifiCertificate(). 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

Sub BrickMaster.RefreshWifiStatus()¶

Refreshes the Wi-Fi status (see GetWifiStatus()). 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.

Sub BrickMaster.SetWifiCertificate(ByVal index As Integer, ByVal data() As Byte, ByVal dataLength As Byte)¶

Parameters:	index – Type: Integer, Range: [0 to 1311, 10000 to 11311, 20000 to 24319, 65534 to 216 - 1] data – Type: Byte Array, Length: 32, Range: [0 to 255] dataLength – Type: Byte, Unit: 1 B, Range: [0 to 32]

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.

Sub BrickMaster.GetWifiCertificate(ByVal index As Integer, ByRef data() As Byte, ByRef dataLength As Byte)¶

Parameters:	index – Type: Integer, Range: [0 to 1311, 10000 to 11311, 20000 to 24319, 65534 to 216 - 1]

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.

Sub BrickMaster.SetWifiRegulatoryDomain(ByVal domain As Byte)¶

enable – Type: Boolean, Default: false rootIP – Type: Byte Array, Length: 4, Range: [0 to 255], Default: {0, 0, 0, 0} rootSubnetMask – Type: Byte Array, Length: 4, Range: [0 to 255] rootGateway – Type: Byte Array, Length: 4, Range: [0 to 255] routerBSSID – Type: Byte Array, Length: 6, Range: [0 to 255] groupID – Type: Byte Array, Length: 6, Range: [0 to 255] groupSSIDPrefix – Type: String, Length: up to 16 gatewayIP – Type: Byte Array, Length: 4, Range: [0 to 255] gatewayPort – Type: Integer, Range: [0 to 216 - 1]

Requires WIFI Extension 2.0 firmware 2.1.0.

Sets the mesh specific configuration of the WIFI Extension 2.0.

The enable parameter enables or disables the mesh part of the WIFI Extension 2.0. The mesh part cannot be enabled together with the client and access-point part.

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 SetWifi2MeshRouterSSID(). 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 SaveWifi2Configuration() 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.

Sub BrickMaster.SetSPITFPBaudrateConfig(ByVal enableDynamicBaudrate As Boolean, ByVal minimumDynamicBaudrate As Long)¶

Parameters:	enableDynamicBaudrate – Type: Boolean, Default: true minimumDynamicBaudrate – Type: Long, Unit: 1 Bd, Range: [400000 to 2000000], Default: 400000

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 SetSPITFPBaudrate(). If the dynamic baudrate is disabled, the baudrate as set by SetSPITFPBaudrate() will be used statically.

Virtual Functions¶

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

Function BrickMaster.GetAPIVersion() As Byte()¶

Output Parameters:	apiVersion – Type: Byte Array, Length: 3 0: major – Type: Byte, Range: [0 to 255] 1: minor – Type: Byte, Range: [0 to 255] 2: revision – Type: Byte, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

Function BrickMaster.GetResponseExpected(ByVal functionId As Byte) As Boolean¶

Parameters:	functionId – Type: Byte, Range: See constants
Returns:	responseExpected – Type: Boolean

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by SetResponseExpected(). For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.
