It is a service release for version, which resolves several important items. The list of supported features has remained the same as version

Resolved issues

  1. OSPREY_LDB-1691 - Power consumption in Wi-Fi Idle connection (DTIM 1) is currently above target due to missing software optimization
  2. OSPREY_LDB-1513 - Device will not connect to an AP in ‘mixed mode’ security since WPA (TKIP) is not supported


  1. Updated values for ETSI/FCC INI files
