Hi there, I tried to update my firmware from 2.000 to 3.001 using RS-232 and it failed, now my device is dead even I can't send at commands. Is there a solution?
My SWinSwup v0.0.1.13 config was
wihtout any program running and autostart disabled.
Hi,
This FW upgrtade changes some setting related to the serial port. That is some ASC0 lines are change to GPIO in the initial setup.
Please, Truy to acces to the module over USB to change the settings of ASC0 to "std" to be able to use the serial port again
Regards

Somewhere over the rainbow!!! Looking for the Oz Land!!!
I encountered the same.
Execute these commands on the serialport;
AT+CSCS="gsm"
AT&W
AT^SCFG="GPIO/****/sync","std"
AT^SCFG="GPIO/****/ASC1","std"
AT^SPOW=1,0,0
AT^SLED=2
AT^SCFG="Serial/Interface/Allocation","1"
AT^SCFG="Gpio/****/DCD0","std"
AT^SCFG="Gpio/****/DSR0","std"
AT^SCFG="Gpio/****/DTR0","std"
AT&W
UPDATE
Also you need programming tool which allows you to upgrade the firmware and JRC seperatly. Bacause of thed changed characterset the tool is not able to install the new JRC.
