Hi,

I have a BQ Aqueris E5 HD (Ubuntu Edition). I want to detect that  
phone as a GSM modem (to send AT commands) in my ubuntu 15.10 desktop.  
I have tried the following:

My detect_usb script:

vendor=$1
product=$2
cat <<EOF > /etc/usb_modeswitch.d/mobile
DefaultVendor= $vendor
DefaultProduct= $product
TargetVendor= $vendor
TargetProduct= $product
MessageContent="5553424312345678c00000008000069f030000000000000000000000000000"
#MessageContent="55534243f4fa00000000000000000600000000000000000000000000000000"
#MessageContent="5553424356fb00000000000000000600000000000000000000000000000000"
EOF
service modemmanager restart
service udev restart
rmmod option
rmmod usb_wwan
rmmod usbserial
usb_modeswitch -I -W -c /etc/usb_modeswitch.d/mobile
sleep 2
modprobe usbserial vendor=$vendor product=$product
sleep 2
modprobe usb_wwan
sleep 2
modprobe option
sleep 2
vndr=`printf "%x" $vendor`
prdt=`printf "%x" $product`
echo "$vndr $prdt" > /sys/bus/usb-serial/drivers/option1/new_id



Executing lsusb command on the device shows as follows:

Bus 004 Device 004: ID 2a47:0c02 <------- This apparently is the  
device (no name)
Bus 004 Device 003: ID 0781:5590 SanDisk Corp.
......
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 004: ID 2188:0ae1

Executed the above detect_usb script as follows:

detect_usb 0x2a47 0x0c02

After this, the following message was displayed in /var/log/syslog:

Also trying to send AT commands to the modem (detected as  
/dev/ttyUSB0), fails. The following demo script from python-gsmmodem  
is used:

!/usr/bin/env python

"""\
Demo: handle incoming SMS messages by replying to them

Simple demo app that listens for incoming SMS messages, displays the  
sender's number
and the messages, then replies to the SMS by saying "thank you"
"""

from __future__ import print_function

import logging
import sys

PORT = "/dev/ttyUSB%s" % (sys.argv[1])
BAUDRATE = 9600
PIN = '<My PIN>' # SIM card PIN (if any)

from gsmmodem.modem import GsmModem

def handleSms(sms):
print(u'== SMS message received ==\nFrom: 0\nTime:  
1\nMessage:\n2\n'.format(sms.number, sms.time, sms.text))
print('Replying to SMS...')
sms.reply(u'SMS received: "01"'.format(sms.text[:20], '...' if  
len(sms.text) &gt; 20 else ''))
print('SMS sent.\n')

def main():
print('Initializing modem...')
# Uncomment the following line to see what the modem is doing:
logging.basicConfig(format='%(levelname)s: %(message)s', level=logging.DEBUG)
modem = GsmModem(PORT, BAUDRATE, smsReceivedCallbackFunc=handleSms)
modem.smsTextMode = False
modem.connect(PIN)
print('Waiting for SMS message...')
try:
modem.rxThread.join(230**31) # Specify a (huge) timeout so that it  
essentially blocks indefinitely, but still receives CTRL+C interrupt  
signal
finally:
modem.close();

if __name__ == '__main__':
main()

It returns something as follows:

# python sms_handler_demo.py 0
Initializing modem...

Traceback (most recent call last):

File  
"/usr/local/lib/python2.7/dist-packages/gsmmodem/serial_comms.py",  
line 140, in write

Any idea what could be wrong?

Thanks and Regards,
