Parameter Storage

Several bearer configuration set can be saved.

Calling twice AT+WIPBR=6,<bid>,1 with the same <bid> will store the last

configuration set.

associated with the bearer <bid> into the FLASH memory.

• AT+WIPBR=6,<bid>,0 is used to free the bearer configuration parameters set

associated with the bearer <bid>.

Executing AT+WIPBR=1,<bid> will open bearer <bid> with default parameters of

the bearer when existing.
