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

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. ---
