Have you tried to send SMS using U3G modens? In this topic I will show a example how to send SMS using U3G modens in FreeBSD.<\/p>\n

<\/p>\n

FreeBSD has built in support for this device, just add<\/p>\n

u3g_load=”YES”<\/p><\/blockquote>\n

to your \/boot\/loader.conf and reboot or issue:<\/p>\n

kldload u3g<\/p><\/blockquote>\n

as root.<\/p>\n

Here’s sample Python script to read SMS data. It uses pySerial.<\/p>\n

[code language=”python”]<\/p>\n

# encoding: utf-8
\nimport serial
\nimport time
\nimport types<\/p>\n

# converts UCS2 to UNICODE
\ndef ucs(t):
\nw = ""
\nfor i in range(len(t)\/4):
\nw += unichr(int(t[i*4:i*4+4],16))
\nreturn w<\/p>\n

# sends AT command to modem and receives result
\ndef at(k):
\nglobal ser<\/p>\n

ser.write(k+"\\r")
\nbuf = ""
\nwhile buf[-6:] != "\\r\\nOK\\r\\n":
\nbuf += ser.read(1)
\nbuf = buf[len(k)+3:].split("\\r\\n")[:-2]
\nreturn buf<\/p>\n

# reads SMSes from modem and prints it on screen
\ndef getSMS():
\nsms = at("AT+CMGL=\\"ALL\\"")
\nwhile len(sms) >= 2:
\nmeta = sms[0].split(",")
\nidx = meta[0][6:].strip()
\nsender = ucs(meta[2][1:-1])
\nw = ""
\ndata = ucs(sms[1])
\nsms = sms[2:]
\nprint "From: %s\\nContent:\\n%s\\n—" % (sender,data)
\nkomenda("AT+CMGD="+idx)<\/p>\n

# change your port below
\nser = serial.Serial("\/dev\/ttyU0.0",115200,timeout=5,rtscts=True)
\nser.open()
\nat("AT")
\n# at("AT+CPIN=****") # enter PIN if you have one
\nat("AT+CMGF=1") # puts modem in text mode
\nat("AT+CPMS=\\"SM\\"") # change SMS storage
\nat("AT+CSCS=\\"UCS2\\"") # change encoding
\nwhile True:
\ngetSMS()
\ntime.sleep(0.5)<\/p>\n
