Erratum 11838 related to encryption key size applies to Bluetooth core specification v4.2, 5.0 and 5.1. The erratum is mandatory for CC26x0 or CC13x0 and CC26x2 or CC13x2 devices. This erratum does not impact CC254x devices because CC254x devices implement the Bluetooth core specifications v4.0.
For CC26x0 or CC13x0,
For CC26x2 or CC13x2, an update has been made in the BLE5-Stack version 2.01.02.00 released within the SIMPLELINK-CC13X2-26X2-SDK version 4_10_00_78. If you are using an SDK version prior to 4_10_00_78, you are required to migrate to a newer SDK version.
Both for CC26x0 or CC13x0 and for CC26x2 or CC13x2, some extra test evidence or test report can be required for the qualification process to prove the erratum 11838 has been implemented. Users can find this extra material on E2E [24]. For CC26x2 or C13x2 devices, the BLE5-Stack 2.2.x.x released within the SIMPLELINK-CC13X2-26X2-SDK version 4.40 and later is qualified with TCRL 2020-1. Therefore, no extra test evidences or test reports for erratum 11838 are required.
