I have two problems with Q2687 and Developer Studio.
Q2687 is not responding.
It does’n respond to AT commands on any port.
DwlWin does not work - it can’t connect to the module either via USB or UART1
I put the Q2687 in the “off” state and set the BOOT mode. Then I start the DWLWin and turn on the module. No results though.
Is there a way to do a “factory reset” or upload the firmware/bootlader again in this situation? How?
I get an error each time I try to upload my application through the Developer Studio:
Due to following reasons the file can't be loaded: DWL file read overflow
What does that actually mean, and how to fix it? I’ve tried to reset the Developer Studio and PC, but with no results.
Than you in advance for any help.
Shortly after RESET it is possible to send some AT commands through the USB.
To almost all of them the modem responds: ERROR
The only difference I have noticed are:
AT+CFUN=1 (it restarts the modem)
AT+WDWL responds with +WDWL: 0
