How to Use ER Command for erase the flash
This command is to erase the reports restored in the flash memory before.
Once the GSM signal is weak or other reasons that cause that the device is not able to send reports to the server,
the reports will be restored in the flash memory and re-sent later. In some case, you might want to erase those
reports immediately, and then you can use this command. Please make sure that those reports in flash won’t be
needed anymore before you use it.
Setup Format：#<User Name>, <Password>, <Function Mode er>*
Example：#username,0000,er*
Note: Erasing the flash memory takes about 90 seconds, so the reply will be a bit later than that of other SMS
commands. In generally, the reply will be received in 2-3 minutes.
