For Mode=1: If the main version numbers returned by the AT+WOPEN=2 command do
not match, the command will reply +CME ERROR: 541.

Mode=3 and 4 are only available only if the Open AT embedded application is stopped
(AT+WOPEN=0).

Open AT embedded applications can be resumed with the AT+OPENRES command or
INTERRUPT feature (see +WCFM).

Warning: With Mode 6, any A&D size change will lead to this area format process (this
process will take some seconds on start-up , before the +WIND:3 indication display (up to
1.5 seconds per 64 Kbytes flash sector size can be considered as a maximum; all A&D
cells data will be erased).
