helins.mbus.wired — io.helins/mbus 2.0.0-beta0

Wired meter-bus through the serial port or TCP/IP.

All functions are specified by clojure.spec and might throw in case of IO failure.

When a timeout in milliseconds is given, IO operations will only block for that amount of time when waiting an answer / confirmation from a slave.

close clj

(close connection)

Closes the given connection.

req-ud2 clj

(req-ud2 connection)

(req-ud2 connection primary-address)

Requests user data from the slave and waits for a variable data structure.

Returns nil if a timeout was set and is up.

reset-application clj

(reset-application connection)

(reset-application connection primary-address)

Sends an application reset to the requested slave.

Returns false if a timeout was set and is up, true if everything went well.

send-ud clj

(send-ud connection ba)

(send-ud connection ba primary-address)

Sends user data to a slave.

Returns false if a timeout was set and is up, true if everything went well.

serial-connection clj

(serial-connection path)

(serial-connection path serial-options)

Establishes a Meter-Bus connection on the given serial port.

snd-nke clj

(snd-nke connection)

(snd-nke connection primary-address)

Sends a SND_NKE message to reset the FCB (frame counter bit).

Returns false if a timeout was set and is up, true if everything went well.

tcp-connection clj

(tcp-connection host port)

(tcp-connection host port tcp-options)

Establishes a Meter-Bus connection via TCP/IP.
