Python/ltrx apis

Overview

Lantronix provides Python modules with APIs to access features of the PremierWave device more easily from your program.

Note that these APIs require firmware version 7.10 or later.

LtrxCellular

Send and receive SMS messages.

from ltrxlib import LtrxCellular

try:
    cell = LtrxCellular()
    print 'calling sendSMS()...'
    cell.sendSMS("1112223333", "Hello!", 0)  # 3rd argument: 0=ASCII 7 bits, 1=ASCII 8 bits, 2=unicode/utf-8

    print 'calling receiveSMS'
    msg = cell.receiveSMS()
    print 'message: ' + msg
 

LtrxDsal

Access to the Digital input/outputs on the device.

from ltrxlib import LtrxDsal

try:
    dsal = LtrxDsal()

    print 'Reading Digital Input 1...'
    state = dsal.readDigitalInput(1)
    print 'state=' + str(state)

    print 'Reading Digital Input 2...'
    state = dsal.readDigitalInput(2)
    print 'state=' + str(state)

    print 'Setting relay to true'
    result = dsal.setRelay(1, True)

    print 'Reading relay 1...'
    state = dsal.readRelay(1)
    print 'Relay is' + state

    print 'Setting relay to false...'
    dsal.setRelay(1, False)
    print 'Reading Relay...'
    state = dsal.readRelay(1,)
    print 'Relay is' + state
  
    print 'Reading temperature...'
    temp = dsal.readInternalTemperature(1)
