MQTT Reset ?

[Jim]

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. --jim schimpf

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.
