MQTT Reset ?

Question

In the release notes for the IOT SDK (which as the MQTT examples) it says: "Once BLE link is disconnected, lwIP example applications no longer get a global prefix. The only way to start using the examples with the global prefix again is to restart the application." I need to disconnect the BLE link but must also preserve some application settings through the reset. 
 Thanks for the help.

Found a workaround. If I modify the linker file to this: 
 MEMORY
{
 FLASH (rx) : ORIGIN = 0x1f000, LENGTH = 0x61000
 /* Save area for config data */
 CONFIG(rw) : ORIGIN = 0x20002800, LENGTH = 0x0100
 RAM (rwx) : ORIGIN = 0x20002900, LENGTH = 0xd700
}
 
 SECTIONS
{ 
 .mysaveBlock 0x20002800 (NOLOAD) :
{
 KEEP(*(.mysaveBlock))
} > CONFIG
 
 } 
 and then define the variable I need to save as: 
 PEG_CONTROL __attribute__((section (".mysaveBlock"))) pegControl;
 
 This area (256 bytes) is NOT cleared on RESET and so retains my values.
