OS upgrades can be done by the user!

os-upgradeFrom OS v3.06D, upgrades can be done by the user oneself, using IQRF IDE v4.30 (menu Tools – Change IQRF OS Wizard) or higher. Downgrades (down to v3.06D or higher) are possible as well. Whole process is very simple and this short article shows you, how to do it.



  • Just start IQRF IDE version 4.30 and newer.

  • Use Tools → Change IQRF OS Wizard.
