5.3.2 Backup procedure
In case the nominal upgrade mode is not possible (due to critical corruption on
the flash memory), a backup procedure is also available. It requires a
WAVECOM specific software to download the firmware file into the modem.
This tool has to run on a PC connected to the serial bus of the modem.
The necessary signals to proceed with the downloading are: Rx, Tx, RTS, CTS
and GND.
Prior to running the WAVECOM downloader, the modem has to be set in
download mode.
For this, the BOOT signal has to be set to low while powering ON (or reseting)
the modem.
Advise : To reduce the time of the download, it’s possible to change the speed
of the serial link at 115200 bits/s. for that, you have to execute the AT
command below :
1) AT+IPR=115200
2) AT+WDWL
3) file transfer
4) AT+CFUN=1 (reset of the module)
Make attention that after the last command, the serial link will be by default at
9600 bits/s.
