Reset

Unlike to other SoftRF Editions, the Dongle stores settings into a dedicated 6 Kbytes EEPROM memory region. Because of this fact, full firmware install/update procedure will not clear these settings.

In order to reset them into default values:

  • download genuine AcSiP S76G factory firmware from this location, then extract the ZIP archive
  • use these instructions as a reference, but
    • substitute that DFU file with s76g_data.dfu from the ZIP and
    • select 2nd 'Target Id' (DATA Memory)

To make sure that the Dongle settings has become cleared - connect it to a terminal emulation software like PuTTY utility or similar:
