Command
AT+WIOW=2,0
Reset I/O (number 2)
By default (e.g., after a reset), the I/O ports configuration is set by the +WIOM command.
This command is allowed only on a GPIO not allocated by an Open-AT embedded application or
for bus operations.
When the BT chip is switched on, the GPIO5 is not available anymore.
Up to ten I/O ports are available. The <index> value is between 0 and 9.
