UART1 in DATA_MODE, so I can't stop my programm


#1

UART1 in DATA_MODE. my q287 don’t understand AT-commands, how can I fix it?


#2

There is a “1 sec pause, +++,1 sec pause” signal to switch back to AT mode.


#3

I havn’t understand… I’ve tryed to stop programm with “at+wopen=0”, but nothing happenings. What exectly i must to do in my terminal?

There are several ways to do that :

  1. On reset there’s a timeout until the dwl app is started , and there your modem might understand at+Wopen=0 ; if you can’t do that by hand try making a program in something like java , c# or anything that should send “at+wopen=0\r\n” at 100 ms ,
    connect your modem to a computer and start the program to do it’s job.
    If this fails you have another possibility :
  2. You can erase the dwl application , but this will be a bit more complicated .
  • Connect the BOOT signal to 10k resistor and then to GND .
  • Connect ur device to the computer
  • Download & Install DwlWin , mark erase open-at application , choose ur com port and start the program and after that reset several times the wavecom device.
