Does the mode of the dongle change? Do you get the target USB ID?

You can check with "lsusb".

[jianwei]

yes.at last i used the below script
# ZTE MF192

DefaultVendor= 0x19d2
DefaultProduct=0x1517

TargetVendor= 0x19d2
TargetProductList="1518,1519"

MessageContent="5553424312345678000000000000061b000000020000000000000000000000"

NeedResponse=1

1. mode-switch successfully
2. but run the gprs-chat,found some error when run "ATDT *99#"

# cat /var/modem_debug
rAT

AT+CPIN?
+CPIN: SIM PIN

OK
ATH
OK
ATE1
OK
AT+CGDCONT=1,"IP","orangeciweb"
OK
ATDT*99#

who know the reason. thank u very much

Try ATD instead of ATDT.

If that does not work, you may be using the wrong port. Usually, there is more than one ttyUSB port.

If you post the full output of "sudo lsusb -v -d 19d2:1581" we can check which is the right one.

ZTE 192 dongle:

when set the AT+CPIN="1234" >/dev/ttyACM0 in the gprs-chat ,return error.

who know the reason why can't set the AT+CPIN="1234" into the ZTE 192 dongle.


Thank u

[Josh]

You can try to 'escape' the quote marks:

AT+CPIN=\"1234\"
